Asymmetries in weapon size and body size, both contributing to an animal's fighting ability, may be contradictory two Macrobrachium rosenbergii males: One male larger but smaller cheliped than its rival. The aim of the study was determine relevance these asymmetries assessment relative reveal effect asymmetry level on structure contests. Thirty contests were staged between prawns from 'blue-clawed' morphotype 'orange-clawed' morphotype. blue-clawed males 0%, 10%, or 20% length 93%, 45%, 25%...
Mother-offspring relationships were studied in the red-claw crayfish Cherax quadricarinatus during 3 phases: "egg-carrying," "hatching," and "release." The maternal behavior of 16 females dispersal their young monitored with a video camera small- large-sized aquaria. Time allocated to locomotion, aeration, cleaning was computed for each phase. During release phase there an increase mobility reduction time devoted fanning as compared egg-carrying hatching phases. A significant negative linear...
Abstract The agonistic behaviour of the freshwater prawn, Macrobrachium rosenbergii, was studied in laboratory. One hour long contests were conducted between prawns matched to size each three sexually mature male morphotypes this species; Small Males, Orange Clawed males and Blue males. An ethogram established, consisting 18 different acts. These acts classified into indicators dominance or subordinance following application cluster analysis. Prawns consisted usually 3 phases: pre-escalated...
Groups of St Peter's fish Sarotherodon galilaeus were trained during 28 days classical conditioning to respond an acoustic signal by approaching a feeder. Their ability retain the acoustically conditioned behaviour was tested after eight different intervals ranging from 12 188 termination training. Retention tests comprised 7 consecutive retraining and response compared with that naive fish. Fish drastically diminished time. After 55 days, there no apparent expression memory on first test...
The process of learning to associate a visual cue with food was studied in groups common carp Cyprinus carpio and Nile tilapia Oreochromis niloticus by means classical conditioning paradigm. In the first phase study, fishes were conditioned either single‐species or mixed‐species blinking blue light food. second phase, group composition altered so that only single species reconditioned, composed individuals previously paired same other species. groups, rapidly formed an association between...
Females of the red-claw crayfish Cherax quadricarinatus do not undergo external changes that may indicate receptivity. To study mating behavior and develop a behavioral assay for female receptivity, pairs size-matched males females were housed in aquaria each divided two by transparent partition, with tube-shelter on side. Observations shelter occupation conducted daily at 30-min intervals. In addition, pair was allowed to interact 10 min after lifting partition. The almost invariably...
