The study was aimed to update the knowledge on the fish landings of the inland fisheries in Basrah province, Iraq. The species composition, species and total landings, and their trends in six landing sites throughout the study region were evaluated during the year 2020-2021. Species compositions were included seven cyprinids’ species, three cichlids’ species, three mullet’s species, and two species from sparids and silurids. The exotic species, C. carpio, tilapias species and C. auratus dominated the landings constituting 44.2% of the total catch, whereas the highly valued native species (M. sharpeyi, L. xanthopterus, C. luteus and A. grypus) forming only 12.4% of the total catch. The total landing reached 2,427.78 t in 2020 and 2,365.15 t in 2021, and these values were higher than what was recorded during the past years since the year 2009. This is due to the prevalence of aliened species and the increase in the fishing effort, such as the numbers of fishermen and fishing boats. Therefore, in fisheries management point of view, it is essential to enhance the stocks of the native species, minimize the dispersal and impacts of some exotic species, and activate the national regulating fishing, exploitation and protection of aquatic organisms to improve the inland fisheries.

“…Nasir and Khalid (2017) 2015). C. carpio and tilapia species catch showed steady increasing trends in the last years in Basrah province (Nasir and Khalid, 2017;Abood and Mohamed, 2020). During the last few years, the Basrah Agriculture Directorate has released large numbers of young carp from its hatcheries (Personal communication).…”

The purpose of the study was to provide up-to-date information on inland fisheries landings in Basrah province, Iraq. During 2020-2021, the species composition, species and total landings, and trends at six landing locations in the research region were assessed. There were seven species of cyprinids, three species of cichlids, three species of mullet, and two species of sparids and silurids. The foreign species C. carpio, tilapias species, and C. auratus dominated landings, accounting for 44.2% of the entire catch. In contrast, the highly prized native species (M. sharpeyi, L. xanthopterus, C. luteus, and A. grypus) accounted for just 12.4%. In 2020 and 2021, the total landings reached 2,427.78 t and 2,365.15 t, respectively, greater than the previous years since 2009. This is attributable to the frequency of alien species and the rise in fishing effort, as measured by the number of fishermen and fishing vessels. Improving inland fisheries requires enhancing the stocks of native species, minimizing the dissemination and impacts of some exotic species, and activating national regulations governing fishing, exploitation, and conservation of aquatic life from the fisheries management perspective.

“…Now, the tilapia species were found in different waters of the country [3][4][5][6][7][8][9][10][11][12]. The total landing of tilapia species by the inland artisanal fisheries of Basrah Governorate was 864,700 kg during 2017-2019 and came in the third rank with 15.4% of the total fish landings during this period [13].…”

Cichlid species invaded the Iraqi waters in the mid-2000s and are now dominant fish species. The present study was carried out to investigate the age and growth of two cichlid species, Oreochromis niloticus and O. aureus in Garmat Ali River, Iraq from October 2019 to September 2020. A total of 2707 specimens of O. niloticus ranging from 7.0 to 25.5 cm and 1664 of O. aureus varying from 7.0 to 26.3 cm were examined which were captured by various fishing gears. The length-frequency distributions revealed that fish lengths (13.0-18.0 cm) formed 64.1% of the total catch of O. niloticus and 67.2% of O. aureus. The length-weight relationships were W=0.012*L3.109 for O. niloticusand W=0.015*L3.075 for O. aureus, and both species indicated positive allometric growth. The highest values of the relative condition factor were obtained during spring and the values decrease when length of two species increase. Seven age groups were determined for O. niloticus: 9.9, 12.9, 15.6, 17.9, 19.4, 20.4 and 22.2 cm, and for O. aureus: 9.3, 12.5, 15.2, 18.0, 19.4, 21.3 and 22.2 cm. The theoretical maximum length (L∞) was 29.2 cm for O. niloticus and 28.6 cmfor O. aureus. These results can assist in fisheries management and conservation of the fish species in Iraqi waters.
