The ensuing infection can therefore spread rapidly inducing more damaging lesions in the external parts of host especially the gills. In this study, in order to isolate and identify foreign parasites of phytophagous fish in Guilan province, 4 farms were selected by cluster method from silver carp breeding farms around Rasht and 16 pieces of fish in 6 stages for 6 months from April to September 2020. The fish transported live to fish health lab, underwent individual clinical observation of their skin, fins and gills with at least 10 moist extended samples prepared for each part. Isolation and morphometric identification of samples were carried out via microscopic examinations. The collected data were statistically analysed using Excel version 2010 and SPSS 20 software.

So far, many health and financial costs have been incurred in human society due to a lack of timely repairs. Therefore, in modern knowledge to heal all kinds of wounds, reduce repair time and prevent infection, much consideration is paid to the use of natural treatment methods and the use of biological science. In the meantime, seas have opened up a wide range of natural medicines for us. If new pharmacological findings show positive results from aquatic effects such as sea cucumber, sea urchin, starfish, algae and their products such as alginate and chitosan, they can be introduced as antibacterial, anti-coagulant, anti-inflammatory, anti-diabetic, anti-parasitic, anti-viral, antiprotozoan and anti-fungal compounds.

In these products, many repair factors have been proven such as prevention of wounds from infections caused by bacterial, fungal and viral microorganisms, ease of use of the product, cheapness and availability, the ability to clean secretions and protect the skin, prevent the growth of granular tissue and repair fast without allergenic reactions. According to studies, Seaderived products may increase proinflammatory factors and inhibit inflammatory factors, thereby enhancing wound healing. These factors increase the production of cytokines in wound sites. By increasing the command of phagocytic cells, cytokines cleanse the wound and prevent infection. In addition, stimulation of keratinocyte migration to wound edges, proliferation and differentiation of fibroblasts, and regulation of extracellular matrix proteins are mediated by the release of extra cytokines and growth factors.","PeriodicalId":14506,"journal":{"name":"Iranian Journal of Aquatic Animal Health","volume":"186 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75528514","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}
