During the present study an attempt was made to analyse some of the important physico-chemical parameters of the water samples at three different sites of the Manasbal Lake to check the pollution load. Various parameters were analysed for a period of six months from July 2010 to December 2010 on monthly intervals by following standard methods. Among the various parameters recorded the overall Air temperature ranged from 7.2°C to 30.2°C; surface water temperature ranged from 6.1°C to 26.5°C; Secchi-disc transparency from 1.5 m to 4.5 m; Conductivity varied from 149 to 292 μS cm-1; Dissolved oxygen from 2.5 to 8.8 mg L-1; Free Co2 from 0.2 to 13.4 mg L-1; pH from 8.1 to 9.2; Total Alkalinity varied from 126 to 243 mg L-1; Chloride values ranged from 5.9 to 33.5 mg L-1; Total Hardness ranged from 119 to 218 mg L-1; Ammonical Nitrogen varied from 27 to 193 μg L-1; Nitrate Nitrogen varied from 31 to 286 μg L-1; Ortho-Phosphate Phosphorous varied from 4.3 to 33.0 μg L-1 and Phosphate Phosphorous ranged from 83.0 to 261 μg L-1. Almost all the above parameters showed that the pollution load is increasing especially at littoral sites due to agricultural run-off and human settlements disposing sewage, besides anthropogenic stresses in the catchment area. The pH of water of this lake was higher due to calcium intrusion from Kondabal area. Hence, the present study urges the need for immediate remedial measures for protection and conservation of this lake in order to save it from further deterioration.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124950921","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}

The present study shows that the size of the amplified product is 873bp long for D. kashmirensis, 1120bp long in D. aegyptensis and 687bp long in D. guptai revealing that there are intraspecific differences in their base pair lengths. Guanine and Cytocine (G+C) content of three Diplozoon species was found nearly constant for three species i.e., 47% (D. kashmirensis); 47% (D. aegyptensis) and 48% (D. guptai), this GC richness contributes to physical attributes of RNA structures, as there is correlation between GC content and optimal growth temperature. An important observation during the present study has been noticed that Schizothorax niger is infected by all the three species of Diplozoidae; D. kashmirensis; D. aegyptensis and D. guptai, but when all six fishes were collected simultaneously, parasitism by all the parasite species was never observed. Phylogenetic trees Maximum Parsimony (MP), Maximum Likelihood (ML) and Neighbor Joining (NJ) showed that D. kashmirensis and D. aegyptensis share a common host Carassius carassius and S. niger.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127001538","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}

Measures of maturation rate, spawning rate, fecundity, hatch rate and nauplii production rate were obtained. The reproductive performance was found for the imported Specific Pathogen Free (SPF) broodstock from Shrimp Improvement system (SIS), Florida, USA. The no.of spawning, eggs quantity, fertility, hatching rate and nauplii production were lowest in 1st to 3rd spawning when females were 7 months old and increased from 4th spawning rate onwards. As the size of females increased from 30 g to 52 g the mean number of eggs per spawning increased from 150,000 to 442,000. Although female body weight was increasingly larger through the study period and the larger females would be expected to produce more eggs per spawning and hatching. The hatching rate was increased from 3rd spawning onwards. The nauplii production rate (NPR), which is a function of egg production and hatching rate, showed a significant increasing from 48% to 96%. In 10th spawning all the activities were increased. This information can be used to select broodstock for hatchery production.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127094816","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}

The cardinal tetra inhabits the middle and upper Negro River, and its trade corresponds to 60% of the economy of the Barcelos municipality. However, fishery data have yet to be collected to better evaluate the effects of this artisanal fishery on fish populations. The present work presents data obtained from field collection interviews and a sample fishery. The data correspond to the quantity of fish caught per collection region, how many people were involved in the activity, the number of nets used, and the catch volume. Data from fisherman interviews and the type of fishing were compared for corroboration of the findings and to assist in calculating the number of fish extracted from the collecting areas during different times of the year. Altogether, these data were used to determine whether ornamental fisheries are sustainable. The present study shows that a fisheries observatory program is viable for the ornamental fish market and can be combined to increase sales, which emphasizes the preservation and wellbeing of the local communities that are active in this trade, as accomplished by the “fair trade coffee market”. We hope this idea can be pursued further by local authorities, and with better data, the preservation of the aquatic fauna can be prioritized because aquatic fauna preservation increases sales","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117250313","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}
