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 ...

Experimental assessment of the effects of a Neotropical nocturnal piscivore on juvenile native and invasive fishes

Neotropical Ichthyology
We experimentally examined the predator-prey relationships between juvenile spotted sorubim Pseudoplastystoma corruscans and young-of-the-year invasive and native fish species of the Paraná River basin, Brazil. Three invasive (peacock bass Cichla piquiti,

The economic displacement of thousands of fishers in the Pantanal, Brazil: A telling story of small‐scale fisheries marginalization worldwide.

Fish and Fisheries, Volume 25, Issue 6, Page 951-958, November 2024.
Abstract A new policy in the Pantanal wetland, Brazil, aims to economically displace thousands of artisanal fishers from one‐third of the region. The legislation disregards several FAO Voluntary Guidelines for Securing Sustainability in Small‐Scale Fisheries' guiding principles (SSF guidelines). Considering that 2024 marks the 10th anniversary of these

Foraging behavior interactions between the invasive Nile Tilapia (Cichliformes: Cichlidae) and three large native predators

Neotropical Ichthyology
The predator-prey relationships between juvenile Nile Tilapia Oreochromis niloticus and native fish species of the Paraná River basin, Brazil, were experimentally examined. Juveniles of O. niloticus were offered to three native predator species (Salminus

Haematological Parameters of the Hybrid Surubim (Pseudoplatystoma reticulatum x P. corruscans) farmed in Brazil [PDF]

Brazilian Archives of Biology and Technology, 2015
This study evaluated the haematological parameters of the hybrid surubim (Pseudoplatystoma corruscans x P. reticulatum) farmed in intensive and semi intensive system. A total of 240 fish were examined, 120 from fish farm and 120 from a semi-intensive for comparison between the hot and cold season.

Larvae of migratory fish (Teleostei: Ostariophysi) in the lotic remnant of the Paraná River in Brazil

Zoologia (Curitiba), 2015
Fish larvae and adults are morphologically distinct from each other and have different ecological requirements. Research on the dynamics of ichthyoplankton provides valuable information about the early stages of the life cycle of fish.

An individual-based model for evolutionary effects of selective fishing applied to Pseudoplatystoma corruscans

Physica A: Statistical Mechanics and its Applications, 2012
AbstractThis paper proposes an individual-based model that takes into account the evolutionary effects of selective fishing on exploited populations. The model is an adaptation of the Penna model based on the biology of exploited species and characteristics of fishing. Given the importance of the Pintado Pseudoplatystoma corruscans, a native species of

Quality and digestibility of food ingested by various trophic fish groups in the Upper Paraná River floodplain

Revista de Biología Tropical, 2011
Determining quality of food ingested and digestibility can be helpful in understanding the mechanisms that determine trophic plasticity, which is the ability of a given species to use a more advantageous food source at a given time.
