Tartalmi leírás:
This study compared changes in the biochemical composition of muscles and
ovaries of maturing female European eels during hormonal stimulation with carp pituitary
homogenate under controlled conditions and in the development of oocytes. It has been
found that differentiation of oocyte size in eel is visible from the beginning of the gamete
maturation process. This differentiation increases as gonads grow. Furthermore, oocytes
are at different development stages and are still highly differentiated in terms of size during
ovulation. Moreover, the biochemical composition of the body and gonads was found to
change. During the process of maturation, the relative fat content in the eel body decreases
both in the muscles (from 21.99 ± 4.3 to 18.48 ± 3.3 %) and in gonads (from
25.76 ± 2.71 to 15.21 ± 4.7 %), with the changes in ovaries being more rapid. Protein
content in muscles also decreased (from 15.98 ± 3.13 to 12.35 ± 1.6 %) during the
process of female maturation. Different trends were observed for polyunsaturated fatty
acids (EPA and DHA). The total amount of these acids decreased in muscles (P.05)
but increased in ovaries (P[0.05).
