Hoplias malabaricus is a non-migratory fish commonly found in the Mogi Guaçu River basin, mainly feeding on fish, small crustaceans and insects. It forms part of the diet for humans, birds and some mammals. This fish has great nutritional value, with both good quality and good quantities of essential vitamins and amino acids. Regarding parasitic fauna, this fish can host different species of helminths in its gastrointestinal tract. The aim of the present study was to investigate the possible interference of parasitism in the meat yield from H. malabaricus and the centesimal composition. For this purpose, fish specimens were collected from marginal lagoons of the Mogi Guaçu River (Pirassununga, state of São Paulo, Brazil) using hooks and fishing nets. We found that all specimens of H. malabaricus were parasitized by at least one species, including larvae of Contracaecum sp. (Nematoda: Anisakidae). Parasitism did not have any significant influence on centesimal composition, but meat yield was negatively correlated with the abundance of larvae.
马拉巴锯脂鲤是一种非洄游性鱼类，常见于莫吉瓜苏河流域，主要以鱼类、小型甲壳类动物和昆虫为食。它是人类、鸟类和一些哺乳动物的食物组成部分。这种鱼具有很高的营养价值，含有优质且数量充足的必需维生素和氨基酸。关于寄生动物群，这种鱼的胃肠道中可寄生不同种类的蠕虫。本研究的目的是调查寄生现象对马拉巴锯脂鲤鱼肉产量和百分组成的可能影响。为此，使用鱼钩和渔网从莫吉瓜苏河（巴西圣保罗州皮拉松unga）的边缘泻湖采集鱼标本。我们发现，所有马拉巴锯脂鲤标本都至少被一种物种寄生，包括对盲囊线虫属（线虫纲：异尖科）的幼虫。寄生现象对百分组成没有任何显著影响，但鱼肉产量与幼虫数量呈负相关。
