Atlas 23: Ahlstrom, E. H. and H. G. Moser. Distributional atlas of fish larvae in the California current region: flatfishes, 1955-1960. Published June 1975. 23 May 2007 References to the data, published in annual ichthyoplankton data reports are given in the introduction to the Atlas. In addition, these data are available in PDF format on the SWFSC web site at http://swfsc.noaa.gov/publications/swcpub/qryPublications.asp, enter "ichthyoplankton" in the Subject line and "California Cooperative Oceanic Fisheries Investigations" in the Title line. Checking the ALL YEARS button will produce the entire list of available data. The report for each year usually is published about 7-9 months after the fall cruise, and includes notes about nomenclature changes, etc. The ultimate goal is to update the old ichthyoplankton identifications to current standards; the database is updated as re-identifications for each cruise are completed.

THE CALCOFI ATLAS SERIES e-
Thisis the twenty third in a series of atlases containing data on the hydrography and plankton from the region of the California Current. The field work was carried out by the California Cooperative Oceanic Fisheries Investigations’, a program sponsored by the State of California under the direction of the State’s Marine Research Committee. The cooperating agencies in the program are:
California Academy of Sciences California Department of Fish and Game Stanford University, Hopkins Marine Station National Oceanic and Atmospheric Administration, National Marine Fisheries Service2 University of California, Scripps lnstitution of Oceanography
CalCOFI atlases3 are issued as individual units as they become available. They provide processed physical, chemical and biological measurements of the California Current region. Each number may contain one or more contributions. A general description of the CalCOFI program with its objectives appears in the preface of Atlas No. 2.
This atlas was prepared by the Data Collection and Processing Group of the Marine Life Research Program, Scripps lnstitution of Oceanography.

Introduction T h i s a t l a s is a c o m p a n i o n v o l u m e to
CalCOFI Atlas No. 17 in that the distribu- tion charts are limited to the six-year period, 1955 through 1960. The former atlas dealt with six common mesopelagic fish larvae; this atlas deals with eight kinds of flatfish larvae. These include five of the family Pleuronectidae, Microstomus pacificus, Glyp- tocephalus zachirus, Lyopsetta exilis, Paro- phrys vetulus and Pleuronichthys spp (predom- inantly P. verticalis); and three of the family Bothidae, Paralichthys californicus, Citharich- thys stigmaeus and Citharichthys spp.
The distributions are from the samples of six ty-nine monthly CalCOFI cruises made dur- ing the years, 1955 through 1960. Collections made on the wide-ranging NORPAC expedi- tion (August 1955) are not included. No surveys were made in November and Decem- ber, 1960. Occurrences on 5509 and 551 1, two multiple occupancy cruises in the south- ern California channel islands region, are
excluded for C. stigmaeus, C. spp, Parophrys vetulus (5509) and Pleuronichthys spp. The abundance of the larvae by month and year is shown in Table 1 ; a dash indicates exclu- sion of the data for that time sequence.
For Citharichthys spp, Citharichthys stig- maeus, and Lyopsetta exilis, distribution charts are arranged on a monthly basis; for Parophrys vetulus, Paralichthys californicus, and Pleuro- nichthys spp, occurrences over a sequence of three successive months are shown in each chart, i.e., January through March, April through June, July through September and October through December. Only one chart per year is presented for Glyptocephalus zachirus and Microstomus pacificus, which summarizes occurrences from April through J ~ i l y of each year, most records of the two .,xcies being limited to these four months.
Distribution charts were prepared for a species when it occurred in five or more collections (monthly) or stations (quarterly). The number of distribution charts prepared for each species is summarized in Table 2; the pagination of the distribution charts is also shown in this table. As is seen in the charts, coverage of the CalCOFI pattern of stations was more extensive during January through July and October, and often was restricted to a portion of the pattern during the remaining four months. Records of larvae not included in distribution charts are sum- marized in Table 3.
The standard CalCOFI ichthyoplankton hauls are described in a number of the earlier CalCOFI distributional Atlases and in Kramer et al. (1972). The average depth of the oblique hauls was approximately 140 meters, depth of water permitting. The tow was taken at a vessel speed of 1% t o 2 knots. A flow meter fastened in the mouth of the net permitted determination of the volume of water strained during a haul. Estimates of abundance of larvae were made comparable between samples by standardizing the counts t o the number under ten square meters of sea surface.

Figure 1 . Speckled sanddab, Cirharichthys stigmaeus (Jordan and Gilbert)
Larvae of the speckled sanddab, Cirharichrhys srigmaeus, Family Bothidae (Figure 1 : Dis- tribution Charts 2-51 )
Larvae of three species of Citharichthys are illustrated in Ahlstrom (1965): 6.5, 10.0 and 14.75 mm specimens of C. stigmaeus; 6.9, 10.0 and 14.5 mm specimens of C. sordidus; 6.2, 9.0 and 15.3 mm specimens of C. xanthostigma. In Citharichthys both eyes become located on the left side of the head (sinistral). Larvae of C. stigmaeus larger than about 6 mm can be positively identified by the lack of two elongated dorsal rays that develop on the back of the head of 5 to 6 mm specimens of the other two species. Larvae of C. fragilis (not illustrated as yet in literature) also develop two elongated dorsal rays.
As noted above, the records of C. stigmaeus are for specimens about 6 mm and larger. Specimens as large as 37 mm are occasionally taken in the plankton, usually offshore. Al-
though specimens of this species were obtained in all months, largest numbers were taken in June and July. C. stigmaeus was commonly taken on 5509 and 55 1 1, when a grid of closely spaced stations were occupied in the southern California channel islands area on lines 83, 85, 87 and 90 out t o station 60; charts are not shown for these special cruises. On cruise 5509 two vessels separately occupied the grid twice, and on cruise 55 11, one vessel occupied the grid twice. The number of occurrences and standardized counts of larvae of C. stigmaeus for these six coverages of the same grid are as follows: 5509-Black Douglas - I, 24 occurrences, 261 larvae; 5509-Black Douglas - 11, 19 occurrences, 243 larvae; 5509- Paolina T - I, 22 occurrences, 194 larvae; 5509-Paolina T - 11, 31 occurrences, 424 larvae; 55 11 -Paolina T - I, 27 occurrences, 191 larvae; 55 1 1-Paolina T-11, 36 occurrences, 278 larvae.

Figure 2. Pacific sanddab, CithurichthJ7.s sordidus (Girard)
Larvae of other sanddabs, Citharichthys spp, Family Bothidae (Figure 2: Distribution Charts 52-1 15)
There are four species of Citharichthys that are common in the California Current region off California and Baja California: C. sordidus, C. stigmaeus, C x a n thostigma, and C. fragilis. All except C stigmaeus develop two elongated, ornamented rays at the beginning of the dorsal fin and two correspondingly long ornamented rays in the pelvic fins; these rays first form on larvae about 5 mm long. Larvae smaller than 5 mm of the four species are so similar in appearance that they cannot be routinely separated and thus are recorded simply as Citharichthys spp. C. stigmueus larvae larger than 6 mm can be separated readily from larvae of the other three species. Larger larvae of all four species can be identified by using a combination of pigment characters and meris-
tic counts. Since the four species have some- what different distributional patterns, the location of capture has t o be taken into consideration when making identifications. C. sordidus and C. stigmaeus are the common species off California and are distributed as far north as Alaska. C. xunthostigma and C. fragilis occur mostly off Baja California and in the Gulf of California. Larvae of C. xanthostigma are sometimes taken off south- ern California but we have no records for C. fragilis from this area.
Larvae of the four species of Citharichthys comprise over 87% of all flatfish larvae taken on CalCOFI surveys. Larvae are collected during all months, but in largest numbers during June, July and August. They occur along the extent of the CalCOFI sampling pattern, most frequently inshore, but with some specimens occurring considerable dis- tances offshore.

Figure 3. Slender sole, Lyopsetru exilis (Jordan and Gilbert)
Larvae of the slender sole, Lyopsetta exilis, Family Pleuronectidae (Figure 3: Distribution Charts 116-143)
The early life history stages of the slender sole have not been described in previous publications. The eggs are relatively large, measuring 1.6 to 1.7 mm in diameter; they are pelagic, lack ornamentation of the outer shell, have homogeneous yolk and lack an oil globule. The newly hatched larva is approxi- mately 5 mm long. The younger stages of larvae have dorsal and ventral margin pigment, some lateral pigment and pigment in the fin- fold posteriorly. Larvae undergoing notochord flexion and early postflexion larvae have myo- septal pigment outlining the ventro-lateral myomeres between the termination of the gut and the developing caudal fin and similar dorso-lateral myosepta1 pigment along the length of the body; pigment develops over the
gut and along the fan of the pectoral fins. In later stage larvae, pigment concentrates into a series of patches along the dorsal and ventral margins of the body and along the lateral line. Metamorphosis occurs between approximately 18 to 22 mm. Lyopsetta has 1 1 or 12 abdominal vertebrae, 42 t o 47 total vertebrae, 72 to 88 dorsal rays, 57 to 66 anal rays, and 19 caudal rays.
Lyopsetta larvae are collected over an extensive area of the CalCOFI sampling pat- tern, from Cape Mendocino, northern Cali- fornia to Pta. Abreojos, Baja California (see inside rear cover). They have been collected every month except October, most commonly during April and May and only occasionally during August through December. Monthly distributions are shown in 28 charts. The largest counts of larvae were obtained in 1956 and 1957, the lowest counts in 1960 (Table 1 ).

Figure 4. California halibut, Paralichthys californicus (Ayres)
Larvae of the California halibut, Purulichthys culifornicus, Family Bothidae (Figure 4: Dis- tribution Charts 144-160)
California halibut have been identified rou- tinely from CalCOFI collections since 1950, although a developmental series has not yet been published. There are larval series of two species of Paralichthys in the literature. Eggs and larvae of the Atlantic species, P. dentatus (L.) were described by Smith and Fahay (1 970); eggs of the northwest Pacific species, P. olivaceus (Temminck and Schlegel) were described by Pertseva-Ostroumova ( 1961) and larvae by Okiyama (1967). Egg diameter of P. dentatu's is 0.90-1.10 mm (mean 1.02 mm) with a single oil globule 0.18 to 0.31 mm in diameter (mean 0.25 mm). Those of oliva- ceus are 0.83 to 0.96 mm, with a single oil globule 0.13 to 0.19 mm. The eggs have an
unsculptured outer shell, homogeneous yolk and a narrow perivitelline space. Eggs of the California halibut average about 0.90 mm in diameter and have a single small oil globule. Larvae of all three species develop about 5 elongated rays at the anterior end of the dorsal fin prior to notochord flexion; the rays of the ventral fins are not elongated as in Citharichthys. Eye migration begins in the California halibut in specimens as small as 8 or 9 mm; the eyes move either to the right or left side of the head, although sinistral specimens are more common. The following meristics are useful in identifying larvae of the Califor- nia halibut: vertebrae 10 + 25 or 26; dorsal rays, 66 to 76, anal rays 49 to 59; caudal rays 18%; gill rakers 7 to 1 1 + 18 to 23. Larvae of Paralichthys are mostly confined to a coastal band from southern California to southern Baja California.

Figure 5. English sole, Parophrys vetulus (Girard)
Larvae of the English sole, Parophrys vetulus, Family Pleuronectidae (Figure 5: Distribution Charts 161 -1 75)
Eggs and early stage larvae were described by Budd (1 940). The eggs are pelagic, trans- parent, lack an oil globule, have a thin unorna- mented shell and a diameter of about 0.9 mm (0.89 t o 0.93 mm). Budd reported that the newly hatched larva was 2.8 mm long, and that larvae reared for 9 days without feeding were 4.0 mm long. The 6.3 mm larva illustrated by Budd from a plankton haul is not that of P. vetulus. The larvae are only moderately pigmented, as can be seen in the illustrations of the 13 and 16 mm specimens. Pigment outlines myomeres (myoseptal) on the tail portion of the body below the lateral line
xv
and is distributed over the anal pterygio- phores, along the ventral margin of the head and gut, and a t the base of the caudal fin. The larvae are quite slender. The larger one illus- trated (16 mm) is in the early stage of metamorphosis with the eye on the left side beginning to migrate. Metamorphosis is com- pleted by about 20 mm SL. Meristic counts which help in identifying postflexion larvae are: vertebrae 42-45 (ave. 43 .9 , dorsal rays 71 to 86, anal rays 54 to 68, and caudal fin rays, 18.
Although larvae of Parophrys were taken in every month except November, the months of peak abundances were March and April and few larvae were taken during September through December.

Larvae of turbots, Pleuronichthys spp, Family Pleuronectidae (Figure 6: Distribution Charts 176-1 95)
Eggs and early stage larvae were described for three species of Pleuronichthys by Budd (1940). Whereas the eggs of most flatfishes have a smooth, unornamented outer shell, those of Pleuronichthys are covered by an hexagonal pattern extending through the en- tire thickness of the membrane. The eggs of the three species described by Budd can be readily distinguished from one another by size alone. The eggs of P. verticalis average 1.07 mm (1 .OO - 1. I O mm) in diameter, those of P. decurrens average 1.44 mm (1.31 - 1.50), and those of P. coenosus average 1.88 mm. The width of each hexagon on the egg shell is about 0.04 mm in all three species. The newly hatched larvae of P. verticalis are 3.16 mm, those of P. decurrens are 3.8 mm
and those of P. coenosus are 5.54 m m SL. All Pleuronichthys larvae are heavily pig-
mented over the head and body except a t the tail portion of the body near the tip of the notochord or the caudal fin. Larvae of P. coenosus also have the finfold heavily pig- mented throughout, but the finfold pigment is less extensive and distinctively different in the other two species.
Although most specimens of Pleuronichthys larvae can be identified t o species, they were not consistently so identified from our Cal- COFI collections. Hence we are reporting on distributions of Pleuronich th y s collectively. In our collections, Pleuronichthys verticalis larvae outnumber those of the other species by perhaps 10 to 1 and all larvae taken off central Baja California are of this species. For this reason, we are including illustrations of a developmental series of P. verticalis (prepared by Barbara Sumida).

Figure 7. Rex sole, Glyptocephalus zachirus (Lockington)
Larvae of the Rex sole, Glyptocephalus tach - irus, Family Pleuronectidae (Figure 7: Distri- bution Charts 196-201 )
Although the larvae of the rex sole have not been described in the literature, they have been known and identified from CalCOFI collections since 1949. Eggs and larvae have been described for two related species, G. cynoglossus from the Atlantic by C. G. J. Peterson (1904) and G. stelleri from the Pacific by Deknik (1 959), Pertseva-Ostrou- mova (1 96 l ) , and Okiyama ( 1963). The larvae of all three species are strikingly similar in appearance and pigmentation. Glyptocephalus larvae can be readily distinguished from larvae of other pleuronectid flatfish by their pigment pattern, high myomere counts, and slender,
-
elongate bodies. They can attain a large size before transformation; it is not unusual to collect larvae of G. zachirus that are between 50 to 70 mm SL. The meristic counts are high for pleuronectid flatfishes, especially the presence of 62 to 65 vertebrae and 21 to 24 caudal fin rays.
During the six-year period covered in this Atlas, there were only 57 occurrences of Glyptocephalus larvae, with all but two of these taken during the months of April through July. In the six distribution charts presented for the species each represents the summation of larvae taken on four cruises, April through July. Most of the specimens were obtained off central and northern Cali- fornia indicating we are sampling the southern end of its spawning range.

Figure 8. Dover sole, Microstomus pacificus (Lockington)
Larvae of the Dover sole, Microstomus pucifi- cus, Family Pleuronectidae (Figure 8: Dis- tribution Charts 202-207)
Hagerman (1952) reported on the biology of the Dover sole. A batch of running ripe eggs measured 2.05 to 2.57 mm (mean 2.33 mm) in diameter. He illustrates a 11.5 mm specimen and includes a photograph of a 26 mm specimen. We have identified eggs from M . pacijicus from plankton hauls and these are similar in size to the measurements given above (Le., 2.04 to 2.26 mm). The yolk is homogeneous and oil globules are lacking. The embryos are well developed before hatching; they have pigmented eyes, larval pectorals and a developed mouth. Newly
hatched larvae are about 6.5 mm long. Larvae become quite deep bodied and can remain in the larval stage until about 50 mm long. A pair of spines develop on the back of the head. Meristic counts aid in identifying larger larvae; these include the caudal count of 21 t o 22 rays, 50 to 53 vertebrae, 94 to 106 dorsal rays and 80 to 88 anal rays. Because of the large size at hatching, characteristic finfold pigment on preflexion larvae as well as distinctive meristics, there is little difficulty in identifying Dover sole larvae whenever sampled. Larvae are taken chiefly during the four-month period, April through July. These months are combined in each of the six distribution charts of Microstomus.

These maps are designed to show essential details of the area most intensively studied by the California Cooperative Oceanic Fisheries Investigations. This is approximately the same area as is shown in color on the front cover. Geographical place names are those most commonly used in the various publications emerging from the re- search. The cardinal station lines extending southwestward from the coast are shown. They are 120 miles apart. Additional lines are uti- lized as needed and can be as closely spaced as 12 miles apart and still have individual numbers. The stations along the lines are num- bered with respect to the station 60 line, the numbers increasing to the west and decreasing to the east. Most of them are 40 miles apart, and are numbered in groups of 10. This permits adding stations as close as 4 miles apart as needed. An example of the usual identifica- tion is 120.65. This station is on line 120, 20 nautical miles south- west of station 60.
The projection of the front cover is Lambert's Azimuthal Equal Area Projection. The detail maps are a Mercator projection.
