Juvenile fish

The larvae are not able to feed themselves, and carry a yolk-sac which provides their nutrition. Before the yolk-sac completely disappears, the tiny fish must become capable of feeding themselves.

The culture of fish larvae requires specific management of ponds to enhance phytoplankton and hence zooplankton production. Fish larvae feed on zooplankton through to the transition to fingerlings. The dynamic characteristics of zooplankton populations have led researchers and commercial hatcheries to use a range of fertilisation regimes. The aims of the management techniques are to maintain high densities of desirable zooplankton species until the fish are harvested or weaned onto commercial feeds.
