Abstract
Ecological and conservation aspects of bycatch fishes: An evaluation of shrimp fisheries impacts in Northeastern Brazil
Highlights
In the Northeastern of Brazil, the shrimp fisheries are predominantly artisanal, carried out mainly by motorized artisanal trawling boats and, in some cases, beach seine
Many species still lack basic knowledge that is required for management and conservation actions, such as length-weight relationships and size at first gonadal maturity and indicators of the ecological roles of the fish species, especially those related to the balancing of the marine food web which may influence the composition of this ecosystem (Elliott et al, 2007)
We provide LWR information and a review of literature addressing the size at first maturity, conservation status, and trophic and functional guilds of thirty-three fishes captured incidentally in a shrimp fishery in Northeast Brazil
Summary
In the Northeastern of Brazil, the shrimp fisheries are predominantly artisanal, carried out mainly by motorized artisanal trawling boats and, in some cases, beach seine. Previous studies focusing on the bycatch species in the northeast of Brazil (Silva-Júnior et al, 2013; Eduardo et al, 2019; Lira et al, in press) provided valuable biological and population information of a variety of species.
