FORMING OF SOME ORGANS OF HEMATOPOIESIS IN PRE-LARVAE, LARVAE AND FRY OF COMMON BREAM (ABRAMIS BRAMA L.)

Ability for hematopoiesis of spleen, intestinal mucosa, and liver is investigated for early ontogenesis of common bream Abramis brama L., a species of bony fish widespread in the Russian waters, including Astrakhan region. The samples (24 ind.) were collected in the fish farm in Kamyzyaksky district of the region in middle May 2018, after hatching. Histological analysis was made by conventional methods. Both spleen, liver, and intestinal mucosa were formed in the first days after hatching. In the spleen, such signs of hematopoiesis as dispersed new developing blood particles were found just in the first day. In the intestinal mucosa, the first foci of hematopoiesis appeared in the nineteenth day. These organs were formed completely by the end of larval development, and the most intense level of hematopoiesis was observed in that time, with forming of blood cells of all rows of hematopoiesis. On the contrary, no signs of hematopoiesis were found in the liver throughout the larval and juvenile periods.

AbstractThe egg release–mating comparison, heterospecific matings and mating success under two hybridization conditions – (i) mixing one sex per species and (ii) mixing both sexes from each species – were investigated to determine whether silver bream Blicca bjoerkna and common bream Abramis brama can hybridize in nature.The results revealed that non-matings in hybridization experiments of silver bream females × common bream males can be explained by territorial and aggressiveness activities observed in common bream. In common bream females × silver bream males, heterospecific matings were observed but their numbers were significantly lower than the spawning numbers, and in this experiment, a female mated with one to four heterospecific males. In mixing both sexes from both species, similar spawning – mating numbers were observed but heterospecific matings accounted for only 27% of the total matings, with 24% accounting for heterospecific matings between common bream females and silver bream males, directly or by opportunism. Mating success was characterized by the occurrence of fertilized eggs after matings.Natural hybridization occurred preferentially between common bream females and silver bream males.
