Length‒Weight and Length‒Length Relationships of Freshwater Fish Species Caught by Professional Fishermen in the Itaipu Reservoir, Brazil

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Length‒weight relationships (LWRs) and length‒length relationships (LLRs) were estimated for 63 and 58 freshwater fish species, respectively, captured in the Itaipu Reservoir, Paraná River Basin, Paraná State, Brazil. Sampling was carried out from March 1987 to July 2024 at 63 professional fishing sites within the reservoir’s area of influence ...

O grau de preferência alimentar: um método qualitativo e quantitativo para o estudo do conteúdo estomacal de peixes

Acta Scientiarum: Biological Sciences, 2008
O método grau de preferência alimentar descreve a alimentação de peixes usando uma simples descrição e computação das preferências alimentares. Esse método é usado quando os valores volumétricos e/ou numéricos para os conteúdos estomacais não são viáveis.

Strategies for aquaculture and conservation of Neotropical catfishes based on the production of triploid Pimelodus maculatus

Aquaculture International, 2019
Triploidization is a technique to produce sterile fish on a large scale. In the spotted catfish Pimelodus maculatus, sterile fish serve as a host of germ cell transplantation for subsequent reconstitution of endangered catfish species. This study aimed to establish an efficient protocol for triploidization in P. maculatus using temperature shock.

Niche preferences and spatial distribution of Monogenea on the gills of Pimelodus maculatus in Río de la Plata (Argentina) [PDF]

Parasitology, 1999
Five Monogenea species were found on the gills of the catfish Pimelodus maculatus in Río de la Plata (Argentina). These were used for studying the preference of species on different gill-hemibranches, niche breadth and niche overlap between species. It was found that congeneric species had a generic-specific preference for certain gill-hemibranches ...

Reynolds shear-stress and velocity: positive biological response of neotropical fishes to hydraulic parameters in a vertical slot fishway

Neotropical Ichthyology
The barriers created by dams can cause negative impacts to aquatic communities, and migratory fish species are directly affected. Fishways have been developed to allow the upstream passage of fishes through dams.
