Abstract

Research with a variety of aquatic ectotherms suggests that variation in individual metabolic rate (i.e., metabolic phenotype) can be a factor that influences the behaviour and growth of individuals. Slow growth, growth disparity and growth depensation have been reported as major drawbacks to spiny ...

Abstract

Zebrafish (Danio rerio) have proven their efficiency as an animal model for genetics and development, but their nutrition and housing requirements continue to elude researchers. Diet and housing density were predicted to affect weight change and reproductive success in 120 days postfertilization...

Abstract

In species with indeterminate growth, differential growth rates can lead to animals adopting alternative reproductive tactics such as sneak-guard phenotypes, which is partially predicted by variation in growth during the juvenile life-history stage. To investigate sources of growth variation, we...

Abstract

Feed efficiency is a trait of high economic importance in fish production, and is highly related to feeding regimes employed and stocking density. However, feed efficiency is difficult to estimate because measurements of individual feed intake are generally not available in fish that are usually...

Abstract

Laboratory observations of 20 similar-size sib fry of pike Esox lucius have been carried out. The fishes were kept from June to September in a single aquarium with abundant food. During their life in a limited space, a temporal community formed with a size structure taking the form typical of a...

Abstract

Individuals often show consistent differences in behavioural traits that may belong to a behavioural syndrome. Aggressive propensity is usually an important component of consistent behavioural types, potentially generating benefits in resource competition with conspecifics that may be traded off...

Abstract

Previous studies indicate that dominant fish grow faster than subordinate fish when fed equal rations. It is unclear, however, whether this growth differential is caused by intrinsic differences related to their propensity to become dominant, or by the extrinsic effect of the social stress...

Abstract

Salmonids are characterized by alternative reproductive tactics, which can lead to an asymmetry in relatedness among offspring within nests and consequently the benefit of discriminating among nestmates. In this study, we examined the effect of paternal reproductive tactic on juvenile behaviour and ...

Abstract

We present an overview of 27 years of experience of domestication and farming of Arctic charr (Salvelinus alpinus) in Sweden. The domestication process included an evaluation of suitable strains for farming, a breeding programme and the study of the biological and behavioural characteristics of the ...

Abstract

Effects of intra- and interspecific competition on diet, growth, grazing, swimming, resting and social behaviour of two carps calbasu (Labeo calbasu) and mrigal (Cirrhinus cirrhosus) were examined in single and mixed species treatments. Three treatments (tanks with 4 L. calbasu, 4 C. cirrhosus or 2 ...
