Length-Weight relationships of 23 fish species from floodplain ecosystems of the Andean Amazon piedmont, Peru

Abstract

SummaryLength-weight relationships (LWRs) for 23 freshwater fish species from the Andean Amazon piedmont in Peru are presented in this study. Fishes were captured between 2009 and 2010 on lagoons from three basins; Amazonas (Ampiyacu and Apayacu) and Ucayali (Pachitea) using gillnets. In this study, new LWRs are reported for 20 species of 23 species analyzed. The study provides new information on less-studied species and can serve as a basis for management of fisheries and conservation of this area.

Length‐weight relationships of fish species from oxbow lakes on the floodplain of the middle Purus River in western Brazilian Amazon

“…These minor deviations in the b values may be derived from environmental conditions, population size, the breeding season (Chuctaya et al, ; Froese, Tsikliras, & Stergiou, ; Zhou et al, ), the availability of feeding resources (Lima et al, ), and even differential shrinkage during the processes of specimen fixation and preservation (Kristoffersen & Salvanes, ; Santos, Silva, Vasconcellos, & Araújo, ), as suggested by Silva et al (). When comparing studies, the b parameter may also vary due to a lack of standardization in the specimen collection methods adopted in different types of habitat (rivers, streams, rapids, and lakes), as suggested by Silva et al ().…”

“…Length‐weight relationships have been widely used in fisheries research (Cella‐Ribeiro, Hauser, Nogueira, Doria, & Torrente‐Vilara, ; Chuctaya, Capitani, Faustino, & Castro, ; Froese, ; Giarrizzo, Bastos, & Andrade, ) and this parameter permits the evaluation of the growth patterns of the populations, as well as the estimation of the condition factor and biomass. These data are fundamental to the sustainable use and management of fish populations.…”

“…Length‐weight relationships are useful tools for evaluating the structure of fish stocks, body shape variations, performance and growth (Chuctaya, Capitani, Faustino, & Castro, ; Lelli, Lteif, Jemaa, Khalaf, & Verdoit‐Jarraya, ). This information is particularly important in the conversion of total length to total body weight and it is possible to estimate fish biomass (Correia, Granadeiro, Regalla, & Catry, ; Siddik, Chaklader, Hanif, Islam, & Fotedar, ).…”

“…Length–weight relationships (LWRs) information is useful in fisheries research for assessing stock structure, alteration in body shape, growth performance and fisheries management (Chuctaya, Capitani, Faustino, & Castro, ; Froese, ; Lelli, Lteif, Jemaa, Khalaf, & Verdoit‐Jarraya, ). Also, such information are particularly important to convert total length into total body weight for estimating biomass of fish (Correia, Granadeiro, Regalla, & Catry, ; Siddik, Chaklader, Hanif, Islam, & Fotedar, ).…”
