Patterns of Abundance and Diversity of Fishes in Iraqi Estuarine and Marine Waters of the Northwestern Arabian Gulf
Scientific study data were collected to determine temporal changes in the patterns and abundance of fish biodiversity and variation in the abundance of fisheries to assess the status of fish populations in Iraqi marine waters. During the study, 159 species of fish were collected, the composition of which included 17 species within eight families belonging to five orders of the cartilaginous fish class, in which the order Myliobatiformes dominated, as well as 142 species, consisting of 56 families, within 17 orders of the class Actinopteri, with the order Acanthuriformes predominating among them. The number of101 commercial fish species were reached 101, while 58 species were recorded for non-commercial species recorded 58 species. A decrease in the number of individuals, species, and monthly weights was observed during the summer season. Rare species were found to be more abundant than resident and seasonal species, with commercial species predominant over non-commercial species within the Tyler subdivision. The average index of diversity, richness, evenness, and dominance was 3.15, 9.60, 0.77, and 0.41, respectively. A decrease in the average length of the four most abundant species in fishing samples was observed. With the allometric growth of these species in relation to length and weight, relative condition index values indicate good and poor health conditions depending on the sensitivity and tolerance of the species to the environment. We concludeIn conclusion, that the estuarine and coastal areas are unique in terms of breeding and feeding migrations, and as serving as a home crucial habitat for young fish. Administrators use this information to make decisions on appropriate management measures to ensure the long-term sustainability of fishery resources.
