The Study of annual shrimp stocks in Masshab (Al-Hammar Marsh), Basrah, Southern Iraq
Inland water prawns, Basra, Iraq
The catch was identified and included two species of shrimp in the waters of the Masshab near Al – Hammar Marsh, Basra, Iraq. During the study period, some of the following environmental factors were recorded, Temperatures are between 20 to 30 ° C; Salinity (‰) between 1.5 to 4.9; The pH value is between 6.9 to 8.0; Turbidity (NTU) between 18.4 to 21.5. The total catch from shrimp, Metapenaeus affinis, and Macrobrachium nipponense was 373,35 ± 12.03 per hour per year, and the monthly catch rate for shrimp was 33.11 ± 12.03 kg per hour per month. The peak of fishing during the summer months was the highest in July, with fishing reaching 47.200 kg per hour during July, while the lowest quantities of fishing were in winter during the January month at 12 kg per hour. The overall catch rate for M. affinis was 124 ± 10.58 kg per hour per year, while the total catch rate for M. nipponense was 241± 13.33 kg per hour per year. The female sex ratio was higher than that of males in two species, M. affinis of males was 21.67, and females were 78.33, while in M. nipponense males were 14.6 to 83.25. And female of M. nipponense bearing of eggs 28.62 ± 34,21 during the year. While non-eggs carriers 71.38 ± 34.21. The period in which females were observed carrying-eggs was determined during the summer months from April to July. The highest percentage of egg-carrying was in July at 88.40% and at January, 11.6%. The longest. M. affinis was 10 cm and the smallest was1 cm, the longest, while M. nipponense and 9 cm and the smallest was 1 cm.
