Introduction: WOVA-FHTM An alternative to traditional practise.
Traditionally, the farmer has been using pituitary gland for controlled spawning in fishes. However, usage of pituitary gland has its own disadvantages. The probability of success is low because it is practically not possible to maintain uniformity in the product.
Besides, it causes handling and post-breeding stress to the brooders, which may lead to death. It is also difficult to handle, store and transport, above all, there is uncertainty about the availability. Problems like those as mentioned above have always forced the farmer to search for alternative products.
WOVA-FHTM can be used for induced breeding in carp and catfish. Performance of WOVA-FHTM has been assessed in some of the government and private hatcheries in Andhra Pradesh, West Bengal, Orissa and other places. Results proved that WOVA-FHTM is a very effective synthetic fish hormone for induced breeding.
