Anableps anableps Anablepidae Cyprinodontiformes Alimentação CNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::COMPORTAMENTO ANIMAL The genus Anableps of the family Anablepidae occurs in brackish or salt water from Central America to the northern part of South America, including the Pacific. This genus has a horizontally divided pupil that allows it to explore the environment above and below the water's surface, hence it is known as a four-eyed fish. In general, the shoals feed in the shallows. The present work aims to identify the feeding habit of Anableps anableps through the analysis of stomach contents. Samples were collected from August 2001 to March 2002 from the Paracauari River (00° 43 'SE48° 31 'W) and tributaries. Collections were made with trawls, puçá and tarrafa nets. The collected material was measured (mm), weighed (g), and the digestive tract was removed. The diet was analyzed based on the frequency of occurrence method. The main food items found were plant material (Diatoms algae) with 27.1%, followed by insects (Hymeunoptera, Coleoptera, Lepdoptera, Hemyptera) with 26.2% and inorganic material (mud and sand) (24%). The least frequent were digested organic material (7.3%); Annelidae (7%); small crustaceans (3.3%) and mollusk (1.6%). The paper concludes that the tralhoto is omnivorous, feeding mainly on insects (arboreal, aerial, aquatic and terrestrial) and algae. Its double vision allows it to live in the intertidal region of the Amazon estuary, exploiting both autoctone (algae) and alloctone (insect) resources. O gênero Anableps da família Anablepidae ocorre em água salobra ou salgada desde a América Central até a região norte da América do Sul, incluindo o Pacífico. Este gênero apresenta a pupila dividida horizontalmente que lhe permite explorar o ambiente acima e abaixo da superfície da água, por isso é conhecido como peixe de quatro olhos. Em geral os cardumes se alimentam nos baixios. O presente trabalho tem como objetivo identificar o hábito alimentar de Anableps anableps através da análise do conteúdo estomacal. Os exemplares foram coletados de agosto de 2001 a março de 2002 no rio Paracauari (00° 43 'SE48° 31 'W) e afluente. As coletas foram realizadas com redes de arrasto, puçá e tarrafa. O material coletado foi medido (mm) pesado (g) e retirado o trato digestivo. A dieta foi analisada com base no método de frequência de ocorrência. Os principais itens alimentares encontrados foram material vegetal (algas Diatomáceas) com 27,1 %; seguido de inseto (Hymeunóptera, Coleóptera, Lepdóptera, Hemyptera) com 26,2% e material inorgânico (lama e areia) (24%). Os menos frequentes foram material orgânico digerido (7,3%); Anelidae (7%); pequenos crustáceos (3,3%) e molusco (1,6%). O trabalho conclui que o tralhoto é omnívoro, se alimentando principalmente de insetos (arborícola, aéreos, aquáticos e terrestres) e de algas. Sua visão dupla permite viver na região intertidal do estuário amazônico, explorando os recursos tanto autoctone (algas) quanto aloctone (inseto). 2023-04-19T18:50:59Z 2023-04-19 2023-04-19T18:50:59Z 2002-07-04 Resumo OLIVEIRA, Valéria de Albuquerque; BARTHEM, Ronaldo Borges; MONTAG, Luciano de Assis F.
