Determination of food rate and fecundity of ( Indomysis nybin i ) (Opossum shrimp) in shrimp ponds of Kollahi port in Hormuzgan province

In this research, fecundity and Determination food rate in I n d o m y s i s n y b i n i (Opossum shrimp) was studied in Indian White Shrimp brood stock ponds of Kollahi port in Hormuzgan province, Iran. Food determination experiment was performed with 4 treatments, T1=5, T2=10, T3=15 and T4=20 Artemia napliuse per mysids. For determination of fecundity, the marsupiums female mysids were analyzed and the juveniles in their marsupium were counted under the loop. Food Determination experiment showed the mysids consumed between 5-9.75 ± 2.2 Artemia naupliuse for 24 hours. The fecundity results showed that the average of larvae was 6.21 ± 2.98 per female. Indomysis nybini mysid was the first mysid species that identified in Hormuzgan and had the total length between 5.5 and 8.2 mm with her fecundity of 2-23 juveniles. The results showed that size of female mysid in this species doesn't have any effect on the numbers of juveniles in marsupum.
