摘要

摘要在水产养殖评估中,长重关系和条件因子被认为是确定鱼类生长、健康和潜在产量的标准方法。进行了一项为期一年的研究,计算了七种鱼类的长重关系(LWRs)和条件因子(K),它们是黑裂腹鱼(Alghad或雪鳟)、曲柳鱼(Sattar雪鳟)、鲤鱼(Common carpio)、鲫鱼(Carassius Carassius),马纳斯巴尔湖的Crossocheilus diplochilus(克什米尔拉丁美洲)和Gambusia holbrooki(蚊子鱼)。结果表明,四种被捕获的鱼类(黑曲霉、曲ifrons、diplochilus和G.holbrooki)表现出负异速生长,而其他鱼类(C.carpio、C.carassius和P.conchonius)表现出正异速生长。所有7种鱼类的LWR均显著低于0.01,决定系数(R2)在0.73至0.96之间。C.carpio的K高于C.carassius、P.conchonius、G.holbrooki、C.diplochilus、S.niger和S.curifrons。目前的研究提供了克什米尔马纳斯巴尔湖七种鱼类的LWR和条件因子,这将有助于鱼类的管理以及评估该湖的生态条件。

Length-Weight Relationship and Condition Factor of Seven Fish Species in Manasbal Lake, Kashmir, India
Abstract For aquaculture assessments, the length-weight relationship and condition factor are considered as standard methods for determining fish growth, its health and the potential yield. A year-long study was conducted to calculate length-weight relationships (LWRs) and condition factor (K) for seven fish species, Schizothorax niger (Alghad or snowtrout), S. curvifrons (Sattar snowtrout), Cyprinus carpio (Common carp), Carassius carassius (Crucian carp), Pethia conchonius (Rosy barb), Crossocheilus diplochilus (Kashmir latia) and Gambusia holbrooki (Mosquito fish) in Manasbal Lake. The results revealed that four captured fish species (S. niger, S. curvifrons, C. diplochilus and G. holbrooki) exhibited negative allometric growth, while other fish species (C. carpio, C. carassius, P. conchonius) exhibited positive allometric growth. LWR was significant at P < 0.01 in all seven fish species, with a coefficient of determination (R2) ranging between 0.73 to 0.96. The K was higher in C. carpio than C. carassius, P. conchonius, G. holbrooki, C. diplochilus, S. niger and S. curvifrons. The current study providing the LWRs and condition factor of seven fish species from Manasbal Lake, Kashmir will be helpful for the management of fish species as well as for assessing the ecological condition of the Lake.

期刊介绍: The Croatian Journal of Fisheries was established in 1938 and today possesses a long-term tradition of publishing papers that deal with both freshwater and marine fisheries. Areas covered by the Journal include ichthyology, aquaculture, ecology and diseases of fish and other aquatic organisms, problems of open waters and other topics related to the fisheries field. Prior to publication, articles pass through rigorous review by senior scientists from around the world. The Journal features articles that reflect original research, interpretative content and subject matter of interest to the fisheries profession.
