The priming and retention of agonistic motivation in male Siamese fighting fish,Betta splendens

Lateral bias of agonistic responses to mirror images and morphological asymmetry in the Siamese fighting fish (Betta splendens).

Behavioural laterality (e.g., during social interactions) is often observed at the individual level in lower vertebrates such as fish, whereas population-level laterality is observed in many higher vertebrates. Population-level laterality can be explained mainly by internal factors (e.g., cerebral lateralization), whereas little is known about the behavioural mechanisms underlying individual-le...

Genetics of the Siamese Fighting Fish, Betta Splendens.

ETTA SPLENDENS more commonly known as the Siamese fighting fish has B been popular in aquariums of western Europe and America for over 35 years. Its domestication and consequent inbreeding antedates the introduction into the West by 60 or 70 years. Selection for pugnacity, long fins (see Figure l ) , and bright colors over this long period has produced a number of phenotypes, none of which is v...

Virulence of Aeromonas hydrophila in Siamese fighting fish (Betta splendens) and the bacterium susceptibility to some herbal plants

Aeromonas hydrophila was isolated from diseased Siamese fighting fish Betta splendens Regans.  The virulence of A. hydrophiala to Siamese fighting fish was conducted by intraperitoneal injection of two doses of bacterial suspensions with 7.5x107 and 7.5x105 cfu per 0.05 ml. The cumulative mortality was observed in high and low dose groups which showed 98.33 and 20 percent, respectively. Moreove...
