Composição corporal e alimentar do Matrinxã, Brycon cephalus (Gunther, 1869), na Amazônia central

In the present paper were studied the diet, the body composition, and the gross energy value of the stomach contents, fillet and liver, as well as some fruits and seeds that are part of the natural diet of the matrinxã, linking these parameters with the river's annual water level flutuations. The ma...

The matrinxã was observed to feed on seeds, fruits, flowers, remains of vegetables and insects, presenting an omnivorous feeding habit. Empty stomaches were frequent (68.5%) in the different hydrologic periods.

During the low water period, protein (24.9%) and ash values (6.3%) were high, and lipids (13.2%) and energy values (416.9 Kcal EB 100g) were low.

Observou-se que a espécie se alimenta de sementes, frutos, flores, restos de vegetais e insetos, apresentando hábito alimentar onívoro. Estômagos vazios foram frequentes (68,5%) nos diferentes períodos hidrológicos. As análises proximais e valor da energia bruta do filé e fígado dos peixes analisados não apresentaram diferenças significativas entre os sexos (P>0,05). No entanto, observou-se diferenças entre os períodos de águas baixas e altas. As médias das composições centesimais e os valores de energia bruta do conteúdo estomacal, expressos com base na matéria seca revelaram, na enchente, um baixo teor de proteína (8,9%) e cinza (1,3%), alto valor de lipídios (70,2%) e energia (775 Kcal EB/100g). Na seca, o teor de proteína (24,9%) e cinza (6,3%) foram maiores, porém os teores de lipídios (13,2%) e de energia (416,9 Kcal EB 100g) foram mais baixos que na cheia. Foi verificado abundante depósito de gordura cavitária o ano todo, diminuindo em janeiro, mês em que o matrinxã realiza a desova. 2020-04-24T15:16:01Z 2020-04-24T15:16:01Z 2001 Artigo https://repositorio.inpa.gov.br/handle/1/13194 10.1590/1809-43922001313520 pt_BR Volume 31, Número 3, Pags. 509-509 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica
