This document discusses different types of ponds used in aquaculture, including nursery ponds, fattening ponds, and stocking ponds. Nursery ponds are used to rear fish from spawn to fry stage. Fattening ponds allow for feeding and harvesting of larger fish. Stocking ponds involve rearing fingerlings to table size through polyculture of carp species. Proper management of these ponds includes controlling weeds, unwanted fish, and aquatic insects.

fish pond
A fish pond is a reservoir that is stocked with
fish and is used for fish farming in aquaculture.
It is the most common process of fish culture.
It is also used for recreational fishing and
ornamental purposes.

Types of ponds
On the basis of stages of growth there are three types of ponds;
Nursery ponds
Fattening ponds
Stocking ponds

Nursery pond
A pond where spawn is reared up to fry stage is known is nursery pond.
Nursery pond are the subset of rearing pond that house fish during the
most delicate and difficult stages of growth.
Nursery ponds are fertilize prior to the arrival of new batch so there are
plenty of food sources.

Size
Nursery pond should be small and shallow, a pond having 0.02 - 0.06 ha
water area and 1 - 1.5 meter depth are most suitable.
The three days old spawn are stocked.
Fishes are reared for 21 to 90 days to attain a length of 2 to 3 cm.
In practice 10million spawn per hactre are stocked in nursery pond.

Management:
 Management of nursery can be done through;
 Clearance of weed.
 Eradication of unwanted fishes.
 Application of lime.
 Manuring of pond.
 Aquatic insect control.
 Stocking of spawn.
 Supplementary feeding

Fattening ponds
 Fattening ponds are used for the production of food fishes.
 Fattening ponds allow good access for feeds, fertilizers and equipment
 As well as easy transfer of harvested fish to storage ponds or outside market.
 Fish fattening represent the final rearing stage before harvest and sale.
 It concern the stage of fish growth between ±40g to the harvest size fish of 200 to
800g, the individual size determined by the market demand.

Stocking ponds
 Stocking ponds means those pond where rearing of fingerlings to table sized
fish need to be done.
 Polyculture of carps is followed in stocking pond .
 Spring or fall is the ideal time for fish stocking .
 Temperatures are mild and oxygen levels are high so fish growth
is at maximum.

Size
 Ideal depth of stocking pond is 6 to 8 feet.
 Most biological productions occur near the water surface and water
deeper then 8 feet may create condition that lead to oxygen depletion
and fish killed.
