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 کاملTelencephalic lesions and behavior in the teleost Macropodus opercularis (l.): effects of telencephalon and olfactory bulb ablation on spawning and foamnest building.
Behavior during 5-day spawning trials of intact, sham-operated, olfactory bulb-ablated, and telencephalon-ablated male paradise fish, Macropodus opercularis, was investigated. Spawning and nestbuilding were eliminated in the telencephalon-ablated males and unimpaired in the sham-operated and olfactory bulb-ablated individuals. Telencephalon ablation resulted in decreased frequencies of frontal ...
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 کاملAutoradiographic localization of sex steroid-concentrating cells in the brain of the teleost Macropodus opercularis (Osteichthyes: Belontiidae).
Tritiakd estradiol or testosterone was administered to gonadectomized male paradise fish, Macropodus opercularis, to investigate the neuroanatomical location of sex steroidretaining cells. Each male was sacrificed 2 hr following intraperitoneal injection of the labeled hormone. Autoradiograms were prepared, and sections were taken from the entire brain, the anterior spinal cord, and the pituita...
