Interestingly, tilapia breeding behavior Purple: Purple cichlid tilapia points as a member, and continued most of the cichlid specific maternal, during the breeding behavior is even more colorful. Can not have a match with the human form of communication than the words of the fish, the exchange can act evolved so diverse, so people to whom admiration.
When the fertilized egg after completion of purple sea bream, the division of labor between males and females there is a clear differentiation. At this time the male is particularly considerate of its partners, all sorts of female obedience, female dominated so. Every morning, purple sea bream males in the nest will be a routine patrol, the expulsion of all suspected biological, of course, occasionally to a nearby food moment; while the female is brooding at home, close all day with a pectoral flap to increase egg the flow of water, bring enough oxygen to the eggs needs.
About two days, the fertilized egg has hatched larvae, a few forty-five days the larvae begin foraging. Fish at this time led by the female, the male attendant immediately as the fish is about the same to maintain high vigilance. Females tired for a week when the body is nourishing food, and when their needs feeding outlier, it will push to greet the male body, the male is a tacit agreement to bypass the female, the fish catch to take over the task of the female foreman; and female foraging return, but also in the same way "push" on the male, to foreman. As a result, females and males of the foreman of time about 3:1 or so.
Led feeding broodstock fish everywhere, like grazing general, it is truly spectacular. However, broodstock fish to go along not by sight, but in broodstock raised the flow direction with the tail moving. When some fish too far apart due to reasons not feel the traffic signals when the broodstock will be very careful to carrying back those who stray. Once found broodstock feel dangerous falls, then the wave form immediately to shake the fish to pass the command potential, then quiet down once the Aberdeen fish, stay put. When dusk falls, the broodstock fish will be led into the nest, the entire travel process this end, the larvae are in turn waiting for the start of a new day trips.
3 weeks, the fish began to adapt the basic decentralized action, but the scope of action is limited to nest nearby. Broodstock fish this time around is not followed, which began two basic world, and over these days they turn to meet their new next generation! |
