摘要:
This study reports the length-weight relationships (LWR) for seven endemic fish species from streams in the Ivai (Characidium heirmostigmata, Corydoras lacrimostigmata, Curculionichthys oliveirai, Hisonotus pachysarkos, and Cambeva horacioi) and Ivai and Piquiri (Apareiodon vladii and Planaltina kaingang) River basins, Parana State, Brazil. Fish specimens measured and weighed were collected between November 1994 and July 2019, fixed with 10% formalin, and are preserved in 70% alcohol. Measurements were done for standard length (SL-0.1 cm precision) and total weight (TW-0.01 g precision). All coefficient of allometry obtained is within the general range for fishes representing useful tentatives for LWR parameters. We highlight the importance of information about the biology of the endemic fish species in a crucial area for the biodiversity conservation of the Upper Parana River system.
