GROW-OUT (TABLE SIZE) FISH PRODUCTION

This is the rearing of fingerling/juvenile fish to Table size usually weighing 700gm - 1kg on the average, 1.5kg and above. This is highly capital intensive ventures as it requires at least the following.

1. Production tank (concrete, earthen, plastic, wooden)

2. Feed for feeding the fish to table size

3. Enough or adequate water availability

4. Electricity/generator

5. Good quality fingerlings/juvenile

THE PROCESS

Production tank: This is where the fish shall be culture to maturity, these can be made with concrete tank, plastic tank, wooden tank, fiber tank, earthen pond.

A concrete tank for instance is that with vibrated block 6" X 6" X 18" is 9" X 9" X 18", in which the holes are field with pure concrete to fortifying it.

A 6ft X 15ft X 4ft concrete tank can successfully raise a 1000 fish to maturity. A connection of 6 to 12 tanks of he same dimension, connected through the individual outlets, water are channel to the concrete tank through pressure pipe from overhead waters tank or directly from a well, borehole etc. However 4-inches pipe are used for outlet purposes.



FEED

Feed constitutes 70% of total production cost. The feed requirement of catfish are protein, carbohydrate, vitamin, mineral, fat premix etc.

Feed ingredient used mainly for catfish feeding includes soya bean meat, groundnut, cake, fishmeal, palm kernel cake, indomie noodle vitamin premixes, maize, wheat, rice offal, calcium, bone meat etc.

These ingredients are mixed with a particular formation of high protein content with 35-45% crude protein content.

Local feeding milling factory have feed materials in storage to meet the requirement of most farmers need.

WATER QUALITY/QUANTITY

Water is the house or the habitation of the fish.

Inside of which they derive all their respiratory requirement and survival. The fish uneaten foods, food, faeces material, are all inside the water body. It is important that the fish are kept in good quality water environment, which support optimum growth performance of the fish.

Water in adequate quantity is a singular most important factors must be provided, if possible continuously I mean continuous inlet and outlets system, where water goes out and fresh water comes into the pond. This help to extremely reduce the organic loads of the fish pond.

Alternatively, the tank can be drained every day, 2 times weekly, weekly as the case indicate, and also the availability of water.

However, before any catfish farming operation, good quality water in adequate quantity is must pre-requisite.

Water parameter should be monitor for optimum performance.

ELECTRICITY

Power supply to the farm must be adequate, to enable the supply of water from borehole, well or any water reservoir or resources.

Electricity can be obtained from the public supply of electricity; most especially generator of over 7.5KVA on standby must be available on the farm. Therefore provision must be part of farm budget and record keeping.



GOOD QUALITY FINGERLING/JUVENILE

This is the core of the entire venture; good quality fingerlings stock is a guarantee for success.

Good quality fish should be obtained from reputable farms.

You can produce the fish from your own farm to be sure of the quality of food.

THE PROCESS

After the construction of the production tank, removal of limestone effect, fertilization, then re-washing of the fish tank.

Then the fish tank can be stock with fish preferably juvenile.



FEEDING

Every 4 hours or 3 times daily feed the fish with imported feed for 4 weeks then start feeding locally palletized diet.

WATER:Change water at interval of 2 weeks, more depending on the extent of the organic loads.

SORTING

Sort of least 2 weekly separate to the fast growing from the smaller fishes. Water parameter monitoring is important but this can be done easily, usually an experienced farm worker should know when to discharge water (drain out water) add raw water to pond. Farm records are very important here.
