Larval development of Plagioscion squamosissimus (Heckel) (Perciformes, Sciaenidae) of Itaipu reservoir (Paraná river, Brazil) [PDF]
The aim of the present study was to characterize the larval development of Plagioscion squamosissimus (Heckel, 1840) morphometrically, collected at Itaipu reservoir from March 1988 to April 1990. It was obtained the samples monthly, with a conic-cylindrical plankton net with 0.5mm mesh. The morphological description of the larvae of P.

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures. [PDF]
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

The age of 320 specimen of Plagioscion monti and 280 specimen or P. squamosissimus was determined by means of daily rings on the otoliths. The length of the fish were in the range of 0.4 - 15 cm. Within this size interval, the increase in length can be assumed to be linear, and the increase of weight to be an exponential function.

Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]
Abstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.

Abstract Non‐native fish species may generate major ecological impacts on native assemblages. This study aims to assess the potential impact of the introduced Arapaima gigas on native fish assemblages in two oxbow lakes of the Bolivian Amazon. Stable isotope data were used to determine trophic position (TP) and isotopic niche overlap, to evaluate ...

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas
We characterized fisheries in the area of the port city of Riberalta (upper Madeira River basin) and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. A. gigas represented 57.6% of the overall economic value of fish in the region.

Balancing protein and energy in Nile tilapia feeds: A meta‐analysis
Abstract Farmed fish are increasingly grown in intensive and semi‐intensive systems where most nutrients are provided by formulated feeds. These are formulated to minimise costs and optimise growth, notably the rate of muscle protein synthesis (i.e., fillet). Protein synthesis depends on the availability of amino acids (i.e., protein) and energy. Thus,
