Morphological features accompanied by 18 S r DNA analyses indicated that the species is Macrobrachum lar. DNA sequences of specimens of this species from the marsh is deposited at the GenBank for DNA as a new global isolate and was published by The National Center for Biotechnology Information (NCBI), the European Nucleotide Archive (ENA) and DNA Data Bank of Japan (DDBJ). M. lar inhabit deep sections of streams and brackish water, adults live in freshwater, while juveniles can be found in brackish or saltwater, the total length of M. lar recorded in this study was ranged between 72 and 109 mm for males and between 61 and 93 mm for females.","PeriodicalId":403888,"journal":{"name":"Biological and Applied Environmental Research","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129698606","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}

Samples of common carp viscera were collected from local markets in the city of Basrah, which included viscera of the common carp Cyprinus carpio. The most prominent and significant difference was the extraction yield which amounted to 57.14% vs 35.71% (vol./wt.) for the physical and chemical methods, respectively. Other physical properties: refraction index, specific weight, specific gravity, viscosity, cloud point and pour point, Were superior in physical method of the physical method. Measured chemical indices (free fatty acids FFA, fatty acid profile, peroxide value, iodine number and Thiobarbituric acid value TBA) indicated some variability between oil types, the most obvious was FFA which increased significantly from 0.107 to 0.205% for physical and chemical methods, respectively. The sensory tests (color and odor) were in favor of oil extracted with the physical method characterized by a light amber color and a mild fishy flavor.","PeriodicalId":403888,"journal":{"name":"Biological and Applied Environmental Research","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125166106","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}

Samples were collected in October 2019 from two sites in the study area. Some environmental parameters measured were water temperature, pH, electrical conductivity, salinity, sulphate, total hardness, total alkalinity, nitrate and phosphate. Fifty-four species of the euglenoids belonging to six genera were encountered, one belonged to Monomorphina, two belonged to Colacium, 19 to Euglena, 10 to Trachelomonas, seven to Lepocinclis and 15 to Phacus. Thirteen species were new records in Iraq. Ten species were recorded in two sites. Most of the euglenoids found in this study occurred in Haqlan springs and were represented by 40 species in comparison to 24 species in the Euphrates river.","PeriodicalId":403888,"journal":{"name":"Biological and Applied Environmental Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131139825","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}

Fishes were collected by gill nets, cast net and electro-fishing. The index of relative importance (IRI%) of food items was determined by combining the frequency of occurrence and points methods. There were monthly variations in feeding activity and intensity of both species, which decreased in the colder months. Both species were classified as herbivores. The main food items of O. aureus were macrophytes (44.3%), algae (31.4%), diatoms (9.3%), aquatic insects (6.6%) and detritus (6.3%). The diet of C. zillii is composed mainly of macrophytes (60.8%), algae (23.0%), detritus (8.6%) and diatoms (6.4). The trophic niche breadth values varied between 0.217 for C. zillii and 0.360 for O. aureus. The results demonstrated a high degree of dietary overlap between O. aureus and C. zillii, as both species fed on the same food sources","PeriodicalId":403888,"journal":{"name":"Biological and Applied Environmental Research","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122942272","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}
