The life cycle of water mites is very complex and their eggs can be found attached with many aquatic plants. Besides, throughout their larval phase, they co-habit with different insects, and live as the ectoparasites on the bodies and wings of these insects. Nymphs and adults have four pairs of legs while larvae have three. Adults also comprise oval or oblong or elliptical bodies with abdomen and a flattened dorsum [2]. However, depending on the type of habitats and mobility, water mites posses a wide range of morphological variations, such as variable shapes (from rounded to elongate), diverse external morphology with different colours etc. Different species of Hydrachnidia can be used as bioindicators to determine the ecological quality of freshwater habitation [3]. Therefore, genetical, biochemical and ecological analysis on water mites is very essential, since they signify the most essential level of life in fresh water ecosystem.

Growth phenomenon is also one of the most key biological aspects of fish in the population, which exhibits the type of adaptation to environmental conditions [2]. The kutum in the Caspian Sea (Rutilus frisii kutum) belong to the Cyprinidae family [3]. This species can be found all along the southern coast of the Caspian Sea from the river Atrak to the Kora. Vali Abad River, one of the tributaries of Cheshmeh Kileh River, flows in the southeast of Tonekabon city center. It is rain-fed and flows from west to east. The river has a length of 14 km, an average bed slope of 0.7% and flows in bicarbonate and bicarbonate sulfate areas [4]. Many kutums migrate to the Shiroud, Vali Abad, Hawiq, Lemir, Anzali, Sefidrood, Tajan, Babolrood and Gorganrood Rivers to reproduce in the coasts of Iran [5]. Terms of catch and extraction, kutums is one of the most valuable fisheries in the Caspian Sea and contributes more than half of the total catch of bony fish [6]. Overall, 90% of its resources comes from Iran [7]. This fish with its high economic value in the southern shores of the Caspian Sea which depends on conservation [8].","PeriodicalId":262559,"journal":{"name":"Aquaculture and Fisheries Studies","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126280151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water samples for physico-chemical parameters and snails samples were collected and identified on monthly basis following standard methods. From the results; the temperature ranged from 26.5-32°C. The pH was all basic throughout the period of the study which ranged from 8.5-9.2 across all the stations. Dissolved Oxygen concentration ranged from 2.6-5.2 mg/L, while the BOD ranged from 2.2-4.9 mg/L. Nitrate level (0.43-0.83 mg/L) was high, while phosphate concentration (0.24-0.42 mg/L) was relatively low in all the sampling stations. A total number of 7 snail species were encountered. Station 3 had the highest number (403), station 2 with 363 species and station 1 had the lowest with 345 species. The family Viviparidae and Bithyniidae has 2 species each. The Bellamya phthinotropis has the highest number of species followed by Bellamya capillata; and the lowest was recorded among the species of Gebtella barthi. In general, the abundance of snails was higher during the rainy season than during the dry season. Taxa richness determined as Margalef index showed significant difference among the sampling stations. Similarly, diversity indices (Shannon Wiener, Simpson, dominance) also showed significant difference among the sampling stations. Lower values of diversity and Eveness indices were recorded at station 1. Station 2 had the highest record of diversity and eveness indices. Shiroro Lake is moderately organically polluted and adequate measures should be taken to check-mate this.","PeriodicalId":262559,"journal":{"name":"Aquaculture and Fisheries Studies","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125014312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
