At present the Department of Fisheries Engineering follows a syllabus recommended by
ICAR‟s IV Dean's committee headed by Dr. S. L. Mehta from the academic year 2007-08.
The Departments of Fisheries Engineering undertakes various courses of Fisheries
Engineering totaling to 14 credits for the UG program including the Hands-on training
(Experiential learning) and In-plant training.
Initially, the Department started the M.F.Sc. Program in „Fisheries Engineering‟ in the
year 2008-09. However, from the year 2010-11, M.F.Sc. Program in „Fisheries Engineering &

Maharashtra state.
Year of submission: 2010
Name of the Guide: Dr. Ashish S. Mohite
Abstract:
Gill nets for seer fish were operated at the surface or in the column water. PA
multifilament twines having specifications of 210d×2×3 to 210d×12×3 were used according
to the mesh size. The mesh size ranged between 70 to 150 mm. The hanging coefficient of
the gear varied in between 0.40 to 0.67. Hung length and hung depth of each unit varied
from 21.21 to 82.83 m and 6.63 to 11.74 m respectively with the total fleet length of 1098 to
2560 m. Seer fish gill nets were operated in the depth range of 28 to 73 m. PP head rope of 8
mm diameter was used and expanded PVC of 4 to 10 in number per net were used as floats
on head rope. Foot rope and mounting ropes were totally absent. Circular concrete sinkers of
2 to 6 number per unit were attached to the main webbing.
PA monofilament of diameter 0.20 to 0.23 mm and 0.23 mm was used as webbing
material for both drift and encircling type of mackerel gill net respectively. The mesh size
for the mackerel drift gill nets ranged between 52 to 56 mm and for encircling mackerel gill
nets it ranged between 45 to 60 mm. The hanging coefficient of the drift and encircling
mackerel gill net ranged between 0.41 to 0.54 and 0.40 to 0.54 respectively. The hung length
and hung depth of the drifting type of mackerel gill net ranged in between 60.35 to 84.67 m
and 4.50 to 5.69 m respectively. Encircling type had hung length in the range from 38.88 to
76.92 m and hung depth from 8.28 to 17.62 m. The fleet length of drift and encircling
mackerel gill net ranged from 320 to 618 m and 410 to 960 m respectively. The depth of
operation ranged from 10 to 18 m for drift type of mackerel gill net and 18 to 28 m in
encircling type of net. For drift mackerel gill nets PVC of disc shape or plastic round shape
floats of 15 to 40 number per unit were used. For encircling type of net 110 to 140 number
of plastic floats were used. In surface as well as column drift net sinkers of 15 to 26 number
for each unit were used. For encircling type of net oval shape lead sinkers of 50 to 140
number were used.
For pomfret gill net PA monofilaments of 0.23 to 0.32 mm diameter were used as the
material for the main webbing. The mesh size ranged between 100 to 130 mm with the
hanging coefficient of 0.41 to 0.56. Colorless or light green color gill nets were most
commonly used with the hung length and hung depth ranged from 47.25 to 108.57 m and
4.41 to 11.92 m respectively. Pomfret gill nets in Ratnagiri had total fleet length of 182 to
915 m and depth of operation varied between 10 to 55 m. Head rope and foot rope of PP of 3
to 4 mm diameter was used. For surface net operation, 5 to 8 number of floats as well as
sinkers were used and for column net operation two methods of float and sinker arrangement
were used. In the first type 5 to 8 number of floats and sinkers of 10 to 15 number per unit
were used. In the second method, 10 to 15 number of floats and of 5 to 8 number of sinkers
per unit were used.
Shrimp gill net in Ratnagiri was the type of bottom set trammel net with loosely
hung small meshed panel present between two tightly hung large mesh panels. The material
used for inner small mesh panel was of PA monofilament of 0.16 mm diameter and for outer
large mesh panel was of PA multifilament of specification 210d×2×3. Mesh size ranged
from 45 to 50 mm, most common of 46 mm for inner small mesh panel and of 250 to 280
mm for the two outer panels. The hanging coefficient for inner netting panel was 0.42 to
0.49 and for two outer panels was 0.61 to 0.79. Hung length and hung depth of shrimp
trammel nets ranged from 31.64 to 61.82 m and 5.40 to 6.61 m respectively with total fleet
length of 240 to 696 m. The depth of operation ranged from 10 to 18 m. PP head rope and
foot rope of diameter 3 mm were most commonly used and mounting ropes were also
present at both upper and lower side of the main webbing. Disc shape PVC of 46 to 70
number were used as floats on head rope and leads of 60 to 80 in number were used as
sinkers on foot rope.
Main webbing of shark gill nets was fabricated with PA monofilament of 0.50 to 1
mm diameter with mesh size varied from 120 to 200 mm and hanging coefficient of 0.41 to
0.51. Hung length and hung depth for shark gill nets varied from 44.16 to 107.16 m and 5.82
to 9.28 m respectively. The net had a total length of 260 to 456 m and operated at a depth up
to 14 m. Expanded PVC floats of 12 to 20 number and 10 to 18 number of stones were used
as sinkers on 5 to 8 mm diameter of head rope and foot rope respectively.
For capture of sole fish, gill nets were made up of PA monofilament material of 0.23
mm diameter with mesh size varied between 75 to 85 mm and hanging coefficient of 0.42 to
0.46. The hung length and hung depth of sole fish gill net varied from 58.5 to 70.38 m and
3.42 to 3.92 m respectively with the total fleet length of 130 to 160 m and depth of operation
was in between 6 to 15 m. PP rope of 2 to 3 mm diameter was most commonly used for head
rope and foot rope for this type of net. It was observed that, 10 to 20 number per unit of
plastic or PVC floats and lead sinkers of 72 to 100 number per unit were used. Two to four
number of units were joined end to end to form a netting fleet.

Design aspects of rampan and dol nets of Ratnagiri,
Maharashtra state.
Year of submission: 2012
Name of the Guide/Co guide: Dr. Ashish S. Mohite
Abstract:
The observed total length of the rampan operated from Ratnagiri was in the range of
300 to 350 m and depth of 9 to 12 m. The rampan net had three main parts viz., the wing,
shoulder and bunt which were made by fabricating 52 to 54 numbers of vertical sections of
webbing. The rampan were fabricated by PE multifilament twine of 210/5/3. The mesh size
varied in different parts of the net. The mesh size for bunt and wing was 15 to 20 mm and 30
to 40 mm, respectively. The horizontal hanging coefficient was ranged from 0.3 to 0.57
along floatline and 0.38 to 0.55 along sinker line. The average length of sinker line was 300
to 315 m. Plastic floats numbering 4000 to 6750 and spindle shaped lead sinkers numbering
2500 to 3500 were rigged to the rampan net. Rampan from Ratnagiri was operated mainly to
catch mackerel and oil sardine shoals moving in the surface and column waters. The rampan
operation was carried out in less than 12 m depth by 16–20 fishermen using non-motorized
wooden boat.
Mosquitodol nets operated from Ratnagiri were 40 to 45 m in length and consisted of
three main parts viz., the mouth, belly and cod end section. A total of 30 to 32 numbers of
the rectangular webbing sections were joined cylindrically to form a full length net. The dol
nets used were made of PE multifilament twine of 210/5/3. The mesh size varied in different
parts of the net from 150 to 145 mm at mouth to 10 to 8 mm at cod end section. The hanging
coefficient for mouth it was 0.50, bunt 0.20 and for cod end 0.51.The fish catch of dol net
consisted of Pony fish, Acetes, Dhoma, Catfish, Shrimps, Lesser sardine and Ribbon fish.
The mosquitodol net operation was carried out by 2–3 fishermen in 18–20 m depth in creek
waters with the help of wooden fishing boat fitted with 1–2 cylinder inboard engines.
Sajachi dol nets operated from Jambhari, Ratnagiri were 68 to 70 m in length and
consisted of the mouth, belly and cod end section and were made of PE multifilament twine
of 210/5/3. The mesh size varied from 160 to 210 mm at mouth to 10 to 15 mm at codend
section. The hanging coefficient for mouth it was 0.58, bunt 0.31 and for cod end 0.88.
Sajachi dol nets operated from Dabhol, Ratnagiri were 55 to 60 m in length and were made
of PE multifilament twine of 210/5/3. The mesh size varied from 160 to 130 mm at mouth to
12 to 10 mm at codend section. The hanging coefficient for mouth it was 0.73, bunt 0.33 and
for cod end 0.66. Two thermocol floats were used as marker floats and a pair of khunts were
used for fixing the net. The operation was carried out by 2–3 fishermen in 18–20 m depth in
creek waters with the help of wooden fishing boat fitted with 1–2 cylinder inboard engine.
