Ecologia alimentar do robalo Centropomus undecimalis Bloch 1792 (Teleostei, Centropomidae) na região costeira do Maranhão

Abstract: A ecologia alimentar de uma determinada espécie faz parte e interfere diretamente na dinâmica de sua população, se tornando relevante para a conservação do ecossistema. Desta forma, este estudo permitiu estudar os principais aspectos da ecologia trófica, além da estratégia alimentar e possíveis variações ontogenéticas na alimentação do robalo Centropomus undecimalis no município de Tutóia - MA. A metodologia realizada constou na identificação e retirada dos dados biométricos e dissecação de 147 estômagos para … Show more

“…Martinelli (2010) also found similar data regarding the allometry of C. undecimalis in Ponta Negra, Natal, Rio Grande do Norte, and Gassman et al (2017) found similar data in their studies with this species in Venezuela. The positive allometry of females can be attributed to the availability of food resources in the study environment, to the fact that females need more energy for reproduction, to the food ecology strategies of the common snook described by Nascimento et al (2021) and Souza et al (2021) in the Tutóia region, state of Maranhão, as well as to the fact that the study area is inserted in the Parnaíba Delta Environmental Protection Area (EPA), a sustainable use conservation unit administered by The Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA), created by a decree (no number) of 08/28/1996, at the request of environmentalists to protect the coastal ecosystem formed by mangroves and dunes located in the states of Maranhão and Piauí (Brasil, 2002;Silva, 2018).…”
