Social 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 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 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...

Guppy, Poecilia reticulate, is a member of the Poecilidae family. This species is viviparous and one of the most popular ornamental fish in the world, whose phenotype is usually determined during the last ten days of pregnancy. However, most differentiation and development of secondary sexual traits are formed during adolescence, i.e. about 16 weeks after birth. These secondary characteristics ...

Many fishes are able to jump out of the water and launch themselves into the air. Such behavior has been connected with prey capture, migration and predator avoidance. We found that jumping behavior of the guppy Poecilia reticulata is not associated with any of the above. The fish jump spontaneously, without being triggered by overt sensory cues, is not migratory and does not attempt to capture...
