In early January 2015, the researchers produced the first juveniles (Solea solea) from farm raised parents outside the season.
The parents were selected for a breeding programme and made it possible to produce a new generation of improved sole juveniles that grow much better.
Year-round production of juveniles is essential for optimal production in fish farming and for meeting the consumer’s needs in terms of size and consistent quality.
Three fish farms in Nova Scotia, Canada, have suffered fish mortalities due to unusual extreme cold water temperatures.
Although during most winters, Nova Scotia's marine waters stay above freezing, this year sustained cold air temperatures caused the water to drop below 0°C.
Tides in late February and early March also tend to be high, and contribute to lowering temperatures in sea cages by flooding more shallow areas than usual. Low air temperatures cool the water and receding tides flush the cages with superchilled water.
Indian shrimp exports are expected to reach $17 billion by 2017, according to the Associated Chambers of Commerce & Industry of India (Assocham).
In line with increasing exports, Assocham is promoting the development of shrimp aquaculture in the country's brackish waters, which is currently under used.
West Bengal has the largest available brackish water area of over 400,000 hectares but yet the state has only brought a meagre 12 per cent of the area for aquaculture.
