The effect of different photoperiod on growth and survival in guppy larvae (Poecilia reticulata)
Growth in animals is controlled by genetic, environmental, and nutritional factors, including external factors (temperature, pressure, salinity, and light) in the evolution of cold-blooded animals. In this study, the effects of three different light treatments on the growth and survival rates of guppy larvae (Poecilia reticulata) were investigated. The larvae of this species with an average ini...
متن کاملThe effect of dietary oxymetholone on growth, survival and reproduction of guppy (Poecilia reticulata)
To check the ability of guppy fish (Poecilia reticulata) to receive high dietary doses of oxymetholone hormone and its effects on growth parameters, survival and reproduction, 300 fish at the age of 10 weeks, with an average weight of 0.38 ± 0.09 g were randomly assigned to 5 treatments and 3 replications in 15 glass aquaria (100 liters volume). Hormone levels were considered as 5 different dos...
متن کاملSocial networks in the guppy (Poecilia reticulata).
Social network theory is used to elicit details of the social structure of a population of free-ranging guppies, Poecilia reticulata. They were found to have a complex and highly structured social network, which exhibited characteristics consistent with the 'small world' phenomenon. Stable partner associations between individuals were observed, a finding that fulfils the basic prerequisite for ...
متن کاملStudies of In Vitro Embryo Culture of Guppy (Poecilia reticulata)
Different with other fishes, the guppies (Poecilia reticulata) is ovoviviparity, which retain their fertilized eggs within the follicle throughout gestation. The synchronously growing diplotene oocytes store nutrients in droplets and yolk, before their maturation and fertilization. The lecithotrophic strategy of development entails the provisioning of embryos with resources from the maternal yo...
متن کاملEffect of waterborne copper oxide nanoparticles and copper ions on guppy (Poecilia reticulata): Bioaccumulation and histopathology
The aim of the present study was to investigate the effect of copper oxide nanoparticles (CuO-NPs) and copper ions (Cu++) on guppy (Poecilia reticulata), in order to assess Cu uptake in the gill, and histopathology of gill and intestinal organs in semi-static regimes for 10 days. Guppy fish were assigned into three groups; one control group, and two experimental groups receiving 20 µg/l of eith...
