Early behavioral experience and adult social behavior in the paradise fish, Macropodus opercularis L.
Macropodus opercularis were reared in isolation, with conspecifics, or cross-reared with nonconspecifics. As young adults, cross-reared subjects presented with live conspecific and mirror image stimuli performed social displays less frequently than controls, while isolates did not differ from controls. In a spawning trial, no differences were found between groups. These results suggest that exp...
متن کاملAntipredator behavior in paradise fish (Macropodus opercularis) larvae: the role of genetic factors and paternal influence.
The paradise fish, a small insectivore, coinhabits marshes of Southeast Asia with several predator fish species. Its ability to recognize and avoid harmful fish may depend upon both genetic factors and experience. Here we demonstrate genetic variability between the 20-day-old larvae of two inbred strains of paradise fish (P and S) in predator exploration and avoidance, using predator models. We...
متن کاملCastration and reproductive behavior in the paradise fish, Macropodus opercularis (L.) (Osteichthyes: Belontiidae).
The effects of castration on male spawning behavior, nestbuilding and fertility were measured in a five day spawning trial with an intact female. Spawning and fertility decreased one week following castration while nestbuilding was unaffected. Sham operated males showed normal spawning and fertility. Two weeks postoperatively, fertility and spawning were increased paralleling partial regenerati...
متن کاملThe ontogeny of agonistic behavior and the onset of sexual maturation in the paradise fish, Macropodus opercularis (Linnaeus)1.
Fish 20-100 days of age were observed in brief conflicts with a stimulus fish of similar size and age. Four stages of behavior development were identified, based on quantitative changes in behavior which occurred with increasing age. Relatively little aggressive behavior occurs in the larval stage which includes fish up to about 40 days of age. Juveniles, age 40-70 days, approach, chase, and at...
متن کاملOpisthorchiasis from Imported Raw Fish
Liver fluke infection caused by Opisthorchiidae is a major public health problem in many parts of the Far East, Southeast Asia, and eastern Europe. However, with the growing volume of international travel and population migration, the infection is increasingly diagnosed in countries where the disease is not endemic, particularly in North America. We report an outbreak of acute opisthorchiasis i...
