- Feeding habits of Paralonchurus brasiliensis (Perciformes: Sciaenidae) from south of BrazilPublication . Sedrez, Mário C.; Barrilli, Germano H. C.; Moura, Evelise N. F.; Barreiros, João P.; Branco, Joaquim O.; Verani, José R.Shrimp trawling directly impacts target species and non-target species, altering micro-habitats and marine trophic webs. Thus, the objective of the present research was to analyze the feeding habits of Paralonchurus brasiliensis as a tool to evaluate the impact of trawling on the food chains in marine environments, in the South Atlantic of Brazil. One thousand and nineteen stomachs of P. brasiliensis were dissected after being captured as bycatch of shrimp Xiphopenaeus kroyeri, in Penha, on the north central coast of Santa Catarina, Brazil. The number of stomachs was enough to describe the feeding habits of P. brasiliensis, characterizing it as a carnivorous species and predominantly invertivorous. They also revealed that this species has a diversified and constant diet, with greater consumption of polychaetes, crustaceans, and ofiuroides, among other components of the macrobentos, all closely related to the sediment. It was also found that the target species X. kroyeri is not an important prey in the diet of P. brasiliensis, despite occupying the same habitat. According to the present study, P. brasiliensis can be characterized as a demersal-benthic species, predator, opportunistic and broad trophic spectrum. This work contributes to the understanding of trophic chains of the coastal ecosystems, using the P. brasiliensis as a model.
- Hábitos alimentares de Paralonchurus brasiliensis (Steindachner, 1875) em Penha, SC, Sul do BrasilPublication . Goetten, Maurício Antônio; Bosse, Afonso; Sedrez, Mário C.; Barrilli, Germano H. C.; Verani, José R.; Martins, Mariana de Oliveira; Branco, Joaquim Olinto; Barreiros, João P.Paralonchurus brasiliensis é um Sciaenidae comum no bycatch da pesca de arrasto do camarão sete-barbas (X. kroyeri) no sul do Brasil. A despeito de sua importância ecológica, estudos sobre os hábitos alimentares dessa espécie são ainda incipientes (COSTA et al., 2012). Assim, esse trabalho tem como objetivo analisar os hábitos alimentares de P. brasiliensis, a fim de se avaliar o impacto da pesca de arrasto sobre as cadeias alimentares marinhas costeiras do sul do Brasil.
