Comparative analysis of phylogenetic and fishing effects in life history patterns of teleost fishes ArchiMer
Rochet, Marie-joelle; Cornillon, Pierre-andré; Sabatier, Robert; Pontier, Dominique.
The effects of fishing on life history traits and life history strategies of teleost fishes are analysed by a new comparative method that splits traits into an allometric part (size effect), an autoregressive phylogenetic component, and an environmental component (fishing effect). Both intra- and inter-specific variation of age and size at maturity, fecundity, adult size and egg size are analysed by comparing 84 populations of 49 species submitted to various fishing pressures. Two axes of life history diversification are found among teleosts. One is the well-known slow-fast continuum separating short-lived and early maturing species (like Clupeiformes) From longer-lived species that mature late relative to their size and spawn larger eggs (like salmonids...

Fishing resources in the rio Cuiabá basin, Pantanal do Mato Grosso, Brazil Neotropical Ichthyology
Mateus,Lúcia. A. F.; Penha,Jerry M. F.; Petrere,Miguel.
The rio Cuiabá is one of the most important tributaries of the upper rio Paraguay basin that form the Pantanal wetlands. The fishing resources of the rio Cuiabá basin were studied based on landing data obtained from the Fish Market of the city of Cuiabá, State of Mato grosso, Brazil. A description is given of the composition and origin of the 2000 and 2001 catch. The rio Cuiabá is the main source of fish for Cuiabá, although some fish sold locally comes from the rio Paraguay. The 2000-2001 catch consisted mainly of migratory species. The main landed species were the pimelodids pintado -Pseudoplatystoma corruscans, cachara -Pseudoplatystoma fasciatum, and jaú -Paulicea luetkeni, and the characiforms pacu -Piaractus mesopotamicus, piraputanga -Brycon...
