The gravity flow should be utilized wherever possible to reduce pumping
cost
The physical and chemical properties of the water should be within
acceptable limits
. The site should be easily access~ble by road
Building material for construction should be available nearby to reduce
cost of transport
Susceptibility of the site to flooding
Proximity of good market for sale of seed and fish
Availability of suitable manpower to operate the farm
Availability of transport for the dispatch of fish
Availability of electricity
Availability of brood fishes for the hatchery
Potential impact on neighbors and environment
Planning for Construction of Fish Seed Farm
Before construction of fish seed farm, it requires proper planning. It is
essential that the site be examined carefully in respect of climatic conditions,
soil conditions and water ava~lability. It is necessary to dig 2.5 m deep pits at
fairly close range along a grid and examine soil samples for their physical
and engineering properties. The deep profile of the soil can also be studied
by drilling bore at different locations to understand the ground water
contours. It is also essential to examine the size of the water source which
can provided sufficient quantity of the water round the year. Required test
may be carried out. A detailed contour survey of the site is an essential part
for preparing a master plan of the layout of the site for installation of
hatchery, nursery ponds and water supply and drainage system of the fish
seed farm.
Facilities Required for Installation of FRP Carp Hatchery
Platform
Proper installation of the FRP hatchery unit at one place for a longer period
requires a platform. The platform should be strong to withstand the pressure
of the hatchely unit placed over it. The height of the platform should be such
that eggslspawn are collected in collection tanks through pipes by gravity
flow only. For stability construct the periphery wall with brickshtones
masonry (1:4) from 2 feet below the earth surface up to 1.5-2 feet above the
ground level. Fill the platform with sand up to 2 feet to give the strength. The
top surface of the platform may also be provided with 4 inch concreting
(1:4:8) to make more durable and strong.
