The trend of Hilsa shad Tenualosa ilisha fishery for the artisanal sector in the Iraqi marine water, Northwest of the Arabian Gulf was described for the period from November 2012 to October 2013. The data on shad landing, interviews and a questionnaire for the fishermen as well as demo fishing were attained. Shad landings varied from 4t in February to 95t in April. Shad amounts formed 11.44% of the total catch Shad landing correlated negatively with salinity of water. The catch per unit of effort of shad for fishermen who was involved in the questionnaire ranged between 1.3-5.1 kg/h/1000m to 0.02-3.42 kg/h/1000m for demo fishing. There are several reasons behind the proposed reduction in shad landings in recent years, including the decline in discharges of Shatt Al-Arab River, overfishing and no regulations to protect and manage marine resources

The fisheries of the lower reaches of Tigris river, north Qurna in Basrah Governorate have been analyzed during the period from January to December 2005. The fishing boats used there varied in lengths form 5 to 10m, of which 50% were motorized with 25-75 HP. Seine and drift gill nets are the main fishing gears used, their lengths ranged from 100 to 200m with mesh sizes of 14-100mm and 7-32mm for seine and gill nets respectively. The number of fishermen in each boat varied from 1 to 7. Twenty three fish species were recorded caught in the area, of which eight were marine species, belonging to twelve fish families, in addition to shrimps. The total catches ranged from 629Kg in January - march to 3335Kg in July- September with total catch of 7671Kg. Three species namely catfish Silurus triostegus, crucian carp Carassius carassius and khishni Liza abu comprised 86.93% of the total catches constituting 69.65%, 11.02% and 6.26%, respectively. The average catch per unit of effort was 19.8 Kg/hr/100m for seine nets and 2.42 Kg/hr/100m for gill nets. The diversity and evenness indices for biomass were 1.0 and 0.33, respectively, in July-September and 1.5 and 0.52, respectively, in October-December. The highest similarity index of species composition was between April-June and July-September (87%), and lowest between April-June and January-March (63%).
