Mixed-sex Nile tilapia can perform competitively with mono-sex fish in cage culture

Researchers discuss a comparative production trial between mixed-sex and conventional all-male stocks of tilapia farmed in cages in Thailand. This showed that males can perform as well in mixed-sex culture and that smaller females can boost total cage production. Financial analysis demonstrated why this is not current practice, but indicated that if a market premium could be obtained for non-sex-reversed fish, and/or smaller fish sold into markets where these command a higher price, this could become a more attractive strategy with wider social benefits.

A series of conversations around the implications of climate change in different aquaculture and aquatic food contexts. These particularly feature early-career researchers tackling issues in different parts of the world. They have been produced with financial support from the Belmont Forum and Natural Environment Research Council and we hope they will be a useful contribution to the upcoming COP26.
