Abstract:
... The use of selective breeding is still relatively limited in aquaculture species. Information on such activities is sparse, hindering an overall evaluation of their success. Here, we report on the results of an online survey of the major aquaculture breeding companies operating in Europe. Six main reared fish species were targeted. A total of 31 respondents contributed to the survey, representing ...

Abstract:
... Despite a worldwide boom in tilapia aquaculture, South Africa has failed to follow suit, resulting in a small, very much undeveloped local industry. Much of the justification for this reality lies on the inadequacy of the species used and the stringent legislation preventing the use of the Nile tilapia, Oreochromis niloticus. With momentum gained in recent years, the local industry lobbying for th ...

Abstract:
... Aquaculture is assuming ever more importance in diminishing the pressure on wild stocks in the seas and to satisfy the demand of fish worldwide. Prices of feed used in farming fish are increasing, due to the rise in demand. Research on sustainable sources of feed was recently intensified, and insects as meal to substitute soybean and fish meals and fish oils seems a promising field. In particular, ...
