Sex group composition, social interaction, and metabolism in the fish Nile tilapia

Brazilian Journal of Biology
We tested whether the fish Nile tilapia (Oreochromis niloticus) in a monosex male group spends more energy and displays an agonistic profile, differently from males in male-female groups.

Size‐selective mortality evolutionarily alters collective behaviour in response to predation risk in a zebrafish (Danio rerio) harvest‐induced selection model

Journal of Fish Biology, EarlyView.
Abstract Intensive multigenerational size‐selective mortality has been found to alter collective properties like shoaling via evolutionary adaptations of individual‐level behavioural traits. For example, experimental populations of zebrafish (Danio rerio) experiencing intensive large size‐selective mortality over multiple generations developed less ...

The effect of high rearing densities on the growth of juveniles of the cichlid, cichlasoma managuense (Günther, 1869)

Uniciencia, 1992
Se investigó el efecto del cultivo en alta densidad sobre la tasa de crecimiento de juveniles de guapote tigre. Mientras que la tasa de crecimiento promedio disminuye con la densidad, el crecimiento de los peces más grandes no resultó afectado. Con altas

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods

Journal of Fish Biology, EarlyView.
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Genome-wide protein phylogenies for four African cichlid species [PDF]

, 2017
BackgroundThe thousands of species of closely related cichlid fishes in the great lakes of East Africa are a powerful model for understanding speciation and the genetic basis of trait variation.
