Transcriptome and targeted metabolomics revealed that cholesterol nutrition promotes ovarian development by regulating steroid hormone metabolism in swimming crab

open access: yesAquaculture Reports, 2022
Cholesterol, which acts as a substrate for the synthesis of ovarian sex hormones, could promote ovarian development. However, crustaceans cannot synthesize cholesterol and must obtain it from diet for growth, molt and gonadal development.

Conserving Marine Fishes [PDF]

open access: yesOryx, 1980
Few marine fishes are endangered. But exotic introductions can be a serious threat to native species, especially around isolated islands such as the Hawaii group, where 30 per cent of the world's reef and shore fishes are endemic. Overfishing, pollution, destruction such as dynamiting coral reefs, and collecting for the enormous and expanding trade in ...
