TL;DR: The congener profiles of PBDEs and PCBs in the fish suggest that sources of Penta- and Deca-BDE technical mixtures as well as technical PCB mixture exist in Ghana, while textile operations and associated release of untreated wastewater are likely to be significant sources of HBCDs.

TL;DR: Investigation of differences in body weight at harvest of males and females among different tilapia strains found a large range in the magnitude of body weight differences between sexes across the seven strains, which discusses the potential productivity improvements due to superior growth rates of all-male culture compared to mixed-sex culture intilapia populations differing in the female to male body weight ratio.

TL;DR: Ghanaian tilapia farmers reported high productivity and positive profits in 2019 as discussed by the authors, with an average of GHC 8.82/m2 for farmers active in 2019, despite wide variability in production and profits, the majority of farmers experienced positive profits.

TL;DR: The events leading to the current risk status for S. galilaeus in Israel are discussed and the need for vigilant monitoring and active management to support a more sustainable future for this and other fish communities in this important habitat is highlighted.
