Abstract:
... Information on the life‐history traits of threatened fishes can inform their conservation as they can indicate resilience to environmental change and vulnerability to extirpation and extinction. 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 ...

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 ...

Abstract:
... Mating between different species is ubiquitous in nature. While environmental conditions and population density have been shown to affect the occurrence of heterospecific matings, much less is known about the potential role of individual characteristics. Here, we examined the association between boldness and mate choice to con- and heterospecifics in a cyprinid fish (Pseudaspius sachalinensis) whi ...

However, little is known about the biological and ecological differences between these two ploidy forms. We examined age, body size and growth rates of fish in a mixed ploidy population of M. anguillicaudatus in the Yangtze River basin in China. The sex ratios of both diploid and tet ...

Abstract:
... Jagor's water snake (Enhydris jagorii) is a freshwater snake that is endemic to the Chao Phraya-Ta Chin basin, Thailand. However, habitat change and destruction are the main threats to this snake, where a large area of the wetland has been rapidly transformed into urban and agricultural areas. Moreover, uncontrolled fishing seriously threatens the remaining population of this snake. In order to pr ...

Furthermore, the presence of estrogenic compounds in surface waters has been attributed, in some cases, to the discharge of wastewater treatment plant (WWTP) effluent. The primary objective of the current study was to determine if WWTP effluent contributes estrogens to the surface waters of Nebraska. A ...

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 ...

In this study, we examined the relat ...

Abstract:
... Induced spawning is more inefficient in Clarias magur than in other fish species such as cyprinids and salmonids. Ovulation can be induced in the female C. magur by using pituitary extract or synthetic hormones. However, milt from the male C. magur cannot be obtained by hand stripping because the volume of seminal fluid in the testes is extremely low. Notably, similar problems are observed in othe ...
