Wild fish belonging to four species belonging to different trophic groups were captured at three distances from fish farm facilities: long distance (>5 Km), medium distance (1.5 Km) and close to sea-cages. Flesh, brain, liver and gonads were sampled for fatty acid analysis. Fish aggregated near sea-cages showed accumulation of fatty acids of vegetable origin in the studied tissues, due to surplus feed consumption or via predation of fish that consumed the feed. Gonads accumulated vegetable fatty acids in different manner in the different species, and the species least and most influenced by fish-feeds were selected for gonad histological examination. Results showed an acceleration of the final stages of the oocyte development in fish aggregated near fish farms compared to fish captured at long distance. Differences in oocyte development were more acute in the species which incorporated higher quantities of vegetable fatty acids.

水产养殖废弃物对养鱼场中野生鱼类聚集体的脂肪酸谱和性腺成熟的影响。

在距养鱼场设施三个距离处捕获了属于不同营养组的四个物种的野生鱼：长距离（> 5 Km），中距离（1.5 Km）和近海网箱。采样肉，脑，肝和性腺以进行脂肪酸分析。由于多余的饲料消耗或消耗饲料的鱼的捕食，聚集在海笼附近的鱼在研究的组织中显示出蔬菜来源的脂肪酸的积累。性腺在不同物种中以不同方式积累植物脂肪酸，并选择受鱼类饲料影响最小和最大的物种进行性腺组织学检查。结果表明，与在远距离捕获的鱼相比，在养鱼场附近聚集的鱼卵母细胞发育的最后阶段加快了。
