Abstract:
... Nannochloropsis is one of the most important microalgae utilized as the feedstuff in aquaculture and is emerging model oleaginous microalgae. Recently, different genetic tools such as RNA interference, gene overexpression and gene editing have been developed in Nannochloropsis. However, the available genetic modification methods based on CRISPR technology are rather limited for modulating gene exp ...

Abstract:
... An average of 7.6 M individual fishes, representing 1.8 K species from 125 distinct fish families, are imported into the U.S. annually for the marine aquarium trade. While many wild-caught species are traded annually, there are only ~39 commercial aquaculture businesses in the U.S. (2020), and 96 species commercially available as aquacultured. This study presents a data-driven framework to empower ...

Abstract:
... Mass reproduction is widely used in fish farms because it is relatively easy and inexpensive. It also enables the development of mass selection programmes that provide gains for traits with high heritability. The main weakness of this approach is that it is currently impossible to know which females participated in reproductive events, unless by conducting expensive genomic experiments. We tested ...
