INTRODUCTION
In the summer of 1980, Connors Bros. undertook
with the assistance of the Federal Government, to install
a "Sikitch" sumbersible fish pump aboard the sardine carrier
"Capelco". The aim of this project was to see how effective
this pump was in the East Coast herring and sardine industry,
with particular reference to quality. The original intention
was to compare this pump with handling fish by brail.
Figure 1
This pump has now been tried for two consecutive seasons
and has proven very successful and Connors Bros. would like to
further this project by requesting assistance for the purchase
of this pump, which has been on loan, in order to make it a
permanent installation in our fleet.
Description of Pump
This pump (Fig. 2) is a hydraulically operated vertical
axis centrifugal pump. It differs from other pumps of its
type in its aluminum construction and model design of intake
nozzle. This nozzle, in practice, proved to be one of the most
- 2 -
attractive features of the pump.
Figure 2
This pump worked from a hydraulic system run off the
main engine which delivered fluid through two long hoses
running through the deck and out to the pump. The pump
delivered the fish by means of a discharge hose to a scale
box just forward of the wheelhouse. After being scaled, the
fish were delivered to the hold by means of a chute.
For these trials, this pump was installed aboard the
"Capelco" one of Connors fleet of sardine carriers. The
Capelco is approximately 70' in length and 19' in beam. She
is fourteen years old and of wood construction. This boat is
typical of the larger carriers used to deliver herring and
sardines in the Bay of Fundy.
.Test of Pump
A test of this pump was carried out on October 7, 1980, when
this vessel was collecting fish from stop - seiners (shut - offs) in
Machias Bay. The fish had a medium fat content and were in the 5' - 11'
size range.
Along with the "Capelco" was the "Senator Neil", another
sardine carrier of similar size, but with an 8" Fairbanks - Morse fish
pump. Thus it was possible to evaluate fish pumped at the same time
and the same location with two different pumps.
The fish were pumped aboard the carriers and then carried to
the plant, a trip of some four hours.
Upon landing the fish were evaluated into ways. Firstly, a
sample of 100 fish that went through each pump was examined for number
of bruises, blood spots, gill damage and skin breaks. In general,
neither group of fish demonstrated significant damage. Most defects
noted were quite minor. The results of this test were quite incon-
clusive, with the Fairbanks pump showing more gill damge and the Sikitch
pump, more external blood spots.
These fish were also tested by filleting and grading a sample
of each group in the manner normal for this type of product. In this
test, the Sikitch pump was marginally better, giving 94.7% good fillets,
versus 92.6% with the Fairbanks pump.
The results of these tests are given in table 1.
At the time that this pump was first installed, there was a
summer student at Beaver Harbour evaluating the quality of landed fish
by counting the number of bruises on samples of fish. It was possible
to compare the five loads of fish landed by the "Capelco" with 26
loads from a number of samples. The results are shown in table 2.
As may be seen, the pump from the "Capelco" did show a lesser
occurrence of bruising. However, the standard deviation of these
measurements is quite high. A students "T" test for significant
difference between these averages showed that this difference is not
significant.

Use of Pump
This pump was used for two consecutive seasons to pump a
total of 2003 tons of fish. Details of date, location, gear,
size of fish and amount in each boat load are given in tables
II and III.
In 1981, this pump was used largely to pump large herring
caught by the Bay of Fundy seiner fleet. Its use this season
was curtailed somewhat by the delay in installation of the
pump and a subsequent breakdown of the boat's main engine.
In 1981, quota regulations and the nature of herring market
diminished the size of this fishery and this boat could not be
used to carry herring. Its service this season was restricted
to collecting from local sardine weirs. The nature of the boat
and the current design of weirs precluded the use of a brail, so
it was not possible to compare the use of this pump with that of
a brail. This pump served very well in this function and was
generally considered a success.
Operational Aspects
The operation of this pump is quite different from the
conventional Fairbanks-Morse fish pump.
In the conventional system, the pump is permanently mounted
on deck, in the hold or in the engine room. The pump is piped to
the dewatering box and an intake hose. The pump is most generally
driven by the main engine. When fish are to be pumped, the intake
hose is put over the side amongst the fish. The pump is then
primed by pumping water into the intake hose, and the fish are pumped.

Figure 3
The Sikitch pump is hoisted directly over the side and
started. In very rough weather, hoisting this pump over the
side could present a problem, but its lightweight aluminium
construction makes it easy to handle in all but the most severe
circumstances. This pump can present some handling problems
when pumping from a seine in open water as the boat must be
manoeuvered so as to have the seine between the boat and the
seiner.
When using this pump around sardine weirs, there was a
problem that the weirmen had to cut the twine to allow the pump
to enter. However, such cuts were repairable and reuseable and
this was not perceived to be a major problem.
The physical layout of this pump is quite neat. There is
little gear on deck and there is less gear in the engine room
than with the conventional system. As well, the hoses are
completely drained after use. This is more hygenic and the
pump is less prone to freeze in winter.
Conclusion
Connors Bros. has now had two seasons experience with
this pump. Although the vagaries of the fish market have
necessitated a change in use from herring to sardines, the pump
has proved versatile enough to serve well on both kinds of fish.
Our experiments showed this pump to be slightly superior
to the Fairbanks pump. In practice this pump has proved easy
to use and has a number of operational advantages over the pumps
in present use.
In order to further this experience, we feel it would be
desirable to make this pump a permanent installation. To this
end we would like to present a request for 75% funding to enable
us to carry this out.
