Effect of different feeding rate on reproductive performance of Swordtail (Xiphophorus helleri)
Feeding fish is one of the most important factors in aquatic nutrition. Regarding the importance of nutrition in aquaculture, many studies have been done; However, few studies have been conducted on the effect of different feeding rates on reproductive activity of fish. This experiment was conducted to determine the effect of feeding rates on reproductive performance of the swordtail (Xiphophor...
متن کاملFemale preference for dynamic traits in the green swordtail, Xiphophorus helleri
Analyses of the relationship between female preference and male behaviour have been complicated by correlated variation in factors such as male size and appearance. This study examined the effects of systematically manipulating male behaviour, while holding male morphology constant. Female green swordtails were shown video-recorded sequences of the same male engaging in an active courtship disp...
متن کاملMerging social hierarchies: Effects on dominance rank in male green swordtail fish (Xiphophorus helleri).
When the same set of individuals are placed in different social contexts, some groups members often experience a change in dominance status. We examined the context-dependence of social status using a group fusion protocol in male green swordtail fish (Xiphophorus helleri). Six individuals were matched for size and separated into two groups of three fish. Each triad established a stable hierarc...
متن کاملEavesdropping on visual cues in green swordtail (Xiphophorus helleri) fights: a case for networking.
Aggressive contests probably occur in networking environments where information about fighting ability is conveyed both to an opponent and to individuals peripheral to the fight itself, the bystanders. Our primary aim was to investigate the relative influences of eavesdropping and prior social experience on the dynamics of aggressive contests in Xiphophorus helleri. A bystander's ability to wit...
متن کاملSperm Swimming Velocity Predicts Competitive Fertilization Success in the Green Swordtail Xiphophorus helleri
Sperm competition is expected to favour the evolution of traits that influence the performance of sperm when they compete to fertilize a female's eggs. While there is considerable evidence that selection favours increases in sperm numbers, much less is known about how sperm quality contributes towards competitive fertilization success. Here, we determine whether variation in sperm quality influ...
