“…Values obtained for condition factor showed that both sexes of S. erythrophthalmus were in good condition. A particular seasonal trend was observed, the best condition factor for males and females was noticed during summer 6 . However, the researcher 13 reported that the best condition factors for males and females of S. erythrophthalmus were during autumn.…”

Background and Objective: Studies on fish biology are essential for the sustainable management and conservation of fish biodiversity.This study observed the length-weight relationships and condition factors of common rudd fish, which give us some information about the ecological and nutritional conditions of fish. This information is crucial to fishery management. Materials and Methods: The length-weight relationship (LWR) and condition factors (K) of 270 Scardinius erythrophthalmus caught in Anzali Lagoon from April to August, 2015. Results: The total length and body weight of S. erythrophthalmus ranged from 94-179 mm and 11.98-98.5 g, respectively.A strong positive relationship was observed between length and weight (r = 0.96). There were no significant differences in the condition factors of males and females (p>0.05). The lowest K value was observed in April (K = 1.5±0.04) and the highest in July (K = 2.25±0.34). The sex ratio of 1.0 male: 1.15 female was observed, with no significant difference between males and females (p>0.05). Conclusion: In this study, the regression coefficient (b) in males and females was 3.35 and 3.29, respectively, more than 3.0, which means they have positive allometry growth in both sexes.

The Anzali Lagoon is located on the southern coast of the Caspian Sea in the Guilan province. Nineteen rivers enter the Anzali lagoon, connected to the Caspian Sea (Aminisarteshnizi, 2021). These rivers pass through forests, urban and rural areas, and because of that, the rivers carry a variety of organic, mineral, sedimentary materials, domestic, industrial, and agricultural effluents. Water quality has drastically deteriorated due to the constant industrial, agricultural, and domestic waste disposal in the rivers; the rivers affect Anzali lagoon ecosystems (Fallah & Zamani-Ahmadmahmoodi, 2017). Anzali lagoon is vital for the spawning and nursery of fish and aquatic species. Oriental river prawn (M. nipponense) is natively distributed in the west of Asia, while the population of M. nipponense in the Anzali lagoon was recorded in 2006 (De Grave & Ghane, 2006) and later on spread in northern Iran's water basins

“…The Anzali Lagoon is located on the Southern Coast of the Caspian Sea. The Anzali Lagoon is a large, shallow, eutrophic freshwater wetland, marshes and seasonally-flooded grasslands between land and sea ecosystems and between freshwater and brackish ecosystems form a special ecotone embracing a unique blend of plant and animal communities 1 .…”

Background and Objective: Aquatic plants are the main components of aquatic ecosystems. They play an important role in aquatic environments, reproducing and reconstructing stocks of all aquatic animals. In addition, some animals feed on aquatic plants.Macrobrachium nipponense is an aquatic species that use the aquatic plant as food and a place for reproducing. Therefore, determining the distribution of aquatic plants with the abundance of M. nipponense was essential for a better understanding of the aquatic plant roles in the M. nipponense life cycle. Materials and Methods: In this study, a sample of aquatic plants and M. nipponense during 2017 were taken. Identification and determination of dominant aquatic plants were made in the Anzali Lagoon. Results: The results showed floating macrophytes (Azolla filiculoides, Nelumbo nucifera, Trapa natans, Hydrocotyle vulgaris, Hydrocharis morsus-ranae and Eichhornia crassipes) and submerged macrophytes (Ceratophyllum demersum, Myriophyllum spicatum, Stuckenia pectinata and Potamogeton crispus) were in all of the sampling sites. Canonical correspondence analysis explained 100% of the total variance that correlated with the number and weight of M. nipponense with aquatic plants. The CCA analyses showed the number of M. nipponense was more affected by T. natans and C. demersum while the weight of M. nipponense was more affected by A. filiculoides, Algae and P. crispus. Conclusion:The correlation between aquatic plants and M. nipponense showed a significant correlation among all aquatic plants and the number and weight of M. nipponense. That means all aquatic plant effects on M. nipponense. But Azolla filiculoides (0.96), Trapa natans (0.97) and Algae (0.97) had more correlation coefficients compared to the other aquatic plants.
