Dinâmica reprodutiva e estrutura populacional de Hoplias aff. malabaricus (Bloch, 1794) (Characiformes, Erythrinidae), em açude da Bacia do Rio Taperoá, Paraíba

Abstract: ResumoO presente trabalho teve como objetivo verificar a dinâmica reprodutiva e estrutura populacional da espécie Hoplias aff. malabaricus, no açude Taperoá II, localizado na Bacia do Rio Taperoá, no Cariri paraibano (07º11'44"S, 07º13'44"S). Foram coletados (nos meses de agosto a dezembro de 2002, janeiro a fevereiro e maio a junho de 2003) 67 indivíduos, por meio de redes de espera e tarrafa. A interferência do regime de chuvas no comportamento reprodutivo e no crescimento da espécie foi observada após a aná… Show more

“…This result was expected and is in agreement with other studies in the region, which states Hoplias malabaricus as the top predator species commonly found in aquatic environments of Brazilian semiarid (Paiva 1974, Chaves et al 2009). …”

“…The species spawning in nests, such as the pearl cichlid G. brasiliensis and the traíra (wolf fish, tiger fish) H. malabaricus (Santos, Fontoura, 2000, Chaves et al, 2009, have their recruitment impaired due to increased variations in the water levels of the reservoir. Agostinho et al (2007) argue that fluctuations in water levels in the reservoir, as a result of the dam operations, can be disastrous for species that have eggs adhered to shoreline substrates, or that lay their eggs in nests built on the reservoir shoreline.…”

“…The environments change from completely dry to overflowing in the majority of water systems, sometimes in a short period. In Paraiban semi-arid zones, the hydrological cycle has a great influence on the population structure of fish assembly, but only a few studies have been developed in this region, such as those of Montenegro et al (2006) and Chaves et al (2009). The aim of this work was to determine the population structure of Leporinus piau in Taperoá II Dam, Paraiban semi-arid region, based on length classes, establishing the weight/length relationship and sexual proportion.…”
