Abstract

Análisis multivariado de la morfometría y merística del robalo Eleginops maclovinus (Cuvier, 1830) Morphometric and meristic multivariate analysis in patagonian blennie Eleginops maclovinus (Cuvier, 1830

Characterization of morphological and meristic traits and their variations between two different populations (wild and cultured) of <i>Cichlasoma festae</i>, a species native to tropical Ecuadorian rivers

“…However, Van der Bank et al (1989) attribute less value to the morphologic variables than to meristic counts in the differentiation of populations of the same species. The meristic counts showed a very low variability and overlapped broadly, showing no divergence among the populations, in agreement with several authors (Gacitúa et al, 2008;El-Zaeem et al, 2012;Solomon et al, 2015). These characters, due to their relative stability, cannot give the necessary variability in measurements which is essential for multivariate analysis and stock discrimination studies.…”

“…The cause of variation in the morphometric and meristic characters can be partly attributed to intraspecific variability, which is under the influence of environmental parameters (Wimberger, 1992). Fish are very sensitive to environmental changes and quickly adapt by changing necessary morphometric character (Cabral et al, 2003;Hossain et al, 2010). Morphometric variation between stocks may be applicable for studying short-term environmentally induced variation (Pinheiro et al, 2005).…”

Morphological analysis of Trichomycterus areolatus Valenciennes, 1846 from southern Chilean rivers using a truss-based system (Siluriformes, Trichomycteridae)

“…This type of morphometric analysis has been mostly applied to Chilean marine fish (e.g. Cortés et al 1996, Gacitúa et al 2008), to facilitate interpretation of the biological significance of population structures in species with wide distribution ranges.…”

Hematological changes in Eleginops maclovinus during an experimental Caligus rogercresseyi infestation

“…Although this species is traditionally considered an opportunistic benthic omnivore, recent research indicates that juveniles and adults are opportunistic carnivores capable of feeding in both marine and freshwater environments (EASTMAN; LANNOO, 2008). E. maclovinus is a coastal species generally associated with estuarine systems, has been exploited as a fishery resource in Chile since 1957 (GACITÚA et al, 2008) and also has a great potential to be farmed (VALENZUELA et al, 1999).…”
