Abstract:
... Tu'ini, Capoeta damascina, is a widespread species in the interior basins of Iran. To examine the morphometric variations residing within the taxon, six isolated river systems from the west, south, southwest, and centre of Iran were investigated: Ghárásu, Hánnã, Bãzoft, Eghlid, Ãbãdeh, and Gãmãsiyãb. A total of 240 adult fish specimens ≥180 mm standard length (females: 180-336; males: 186-304) wer ...

Abstract:
... Age structure, growth and size at sexual maturity of smallmouth yellowfish, Labeobarbus aeneus (Burchell), were assessed in 2008–2009. Despite its angling and food importance, little has been published on many aspects of its ecology and biology, specifically its age structure in the Vaal River system. Of 193 L. aeneus collected by gillnetting, 96 were assessed for sexual maturity, and ages were es ...

Using scales for age determination, female and male fish comprised five and four age groups, respectively. The monthly changes in marginal increment ratio suggested that annuli on scales were formed during March thr ...

Abstract:
... Lontra canadensis (River Otter) have been reintroduced throughout much of their former range in North America, but our understanding of the function they serve in ecosystems to which they have been reintroduced remains incomplete. We examined the winter diet of reintroduced River Otters in Kentucky based on contents of 126 stomachs collected over three trapping seasons, 2006–2009. Fish and crayfis ...

Cyprinidae; body size; dimorphism; females; fish; males; mating systems; models; phylogeny; spawning; sperm competition; testes
Abstract:
... Mating systems evolve with sexual size dimorphism (SSD) in many animals. Mating systems with males larger than females occur when males compete for female access or guard territories, while mating systems with group mating tend to occur in species where females are the same size or larger than males. In addition to variation in SSD with mating system, sperm competition varies among mating systems ...

Abstract:
... In recent decades, the link between the exaggeration of male sexual ornaments and ejaculate quality has received much attention. When males with conspicuous sexual ornaments have high-quality ejaculate, females are believed to obtain benefits, such as high fertilization success and offspring with good genes, by choosing mates on the basis of male ornamentation. In this study, we examined the relat ...

Garra ghorensis, a small (< 140 mm total length) riverine cyprinid fish, endemic to the southern Dead Sea area, is critically endangered through habitat loss and invasive species. There are, however, no da ...

Hematological parameters of fish are useful for diagnosing pathophysiological conditions associated with metabolic perturbations in fish and therefore act as a non-specific biomarker of acute and chronic stress in the natural habitat and in aquaculture. Salmonid fish are of great importance in aquaculture; however, hematological studies of these species are scarce. This study presents the first se ...
