Many of these technologies involved the discharge of solids, chemicals, biological agents, or other foreign materials into waters experiencing HABS. Other technologies are also available that could control HABS through the manipulation of environmental conditions such as water salinity, temperature, light intensity and stratification These potential control technologies would essentially accelerate or amplify the development of natural processes that terminate HABs. These technologies can be implemented over the entire range of conditions under which HABs occur and could limit the adverse environmental impacts to other organisms in the HAB impacted area. One of these potential technologies involve the application of the hypersaline concentrate waste water from desalination plants over an area impacted by a HAB. The near surface discharge of the desalination plant hypersaline waste water could an effective means of HAB control by inducing rapid changes in water salinity and stratification. The expected environmental impacts would be temporary, limited in both duration and areal extent. No foreign chemicals, materials, substances, organisms or biological agents would be introduced into the environment. Added benefits would include the beneficial reuse of the hypersaline waste water from desalination plants, reduction of waste water loading to the local area of the desalination plant, and the potential to generate revenue for the desalination plants by the sale of waste water.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126179260","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}

During Hilsa fishing, Pangas (Pangasius pangasius), Koral (Lates calcarifer) and Poa (Johnius coitor) were also found to capture as bycatch using Chandi Jal (set gill net). 85% fishermen were observed to use mechanized (5-40 HP; Horse Power) boats in the study areas. Hilsa fishing was noticed mostly during October-November while such activities was almost absent during February-May (off period) which made fishermen to start migrating temporarily to the nearest urban areas for their livelihood. Although the Government of Bangladesh formulates an act to have fishing license yet 20% of the fishermen were found having valid fishing license in the study areas. Average daily net income of the fishermen during fishing period was 600 BDT whereas their real field daily income through fishing supposed to be 1695 BDT if they are supported by nets, boats, fuels etc. which means almost 64% of their daily income is taken by the aratdars. Therefore, subsidy as a means of nets, boats, fuels, engines etc. might be recommended for the better livelihood of the fishermen in greater Noakhali region.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123454126","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 current data and knowledge on fish populations and fisheries impacts are very poor in this region, particularly in Chad. Therefore, any new knowledge, especially on the structure of the ichthyological stands can be considered as valuable. Information on the status of Lake Iro fisheries resources was thus established by this study, which can serve as a model fisheries management regime in Central Africa. We performed assessment of fish resources in Lake Iro, Chad, achieved by a characterization of the exploited ichthyofauna, and the location of nursery and fishing areas. Results indicated that the overall size range of fish species showed negative effects of fishing pressure on size structure of the fish resources. Fishing has increasingly exerted pressure on fish species and affected the primary consumer species. We hypothesized at Lake Iro fish catches were below optimal fish production levels, essentially due to excessive localized fishing efforts, and selective fishing techniques by fisherman. Such reports call for the development of an integrated plan for sustainable management of Lake Iro fisheries resources. Sustainable and equitable exploitation of Lake Iro resources can be promoted by implementation of the following recommendation: a protected area at the lake inlet to limit excessive juvenile fish catches, which disturbs the aquatic food chain and prevents juvenile fish supply and growth in Lake Iro.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115237986","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}

However, little is known about its biological function in fish hepatocytes. Using tilapia as a model, SLtranscripts were shown to be widely expressed in various extrapituitary tissues with the relatively high expression level in liver. To explore the biological action of SL in hepatocytes, we produced and purified recombinant tilapia SL protein which could induce pigment aggregation in tilapia melanophores. Further, the antiserum for the SL was produced and its specificity was confirmed by antiserum preabsorption. During 4 week starvation, hepatic SL transcripts in starved fish were significantly higher than the control fish starting on the 1st week of starvation until 4th week. After re-feeding, the SL transcripts level returned to normal. Using primary cultures of tilapia hepatocytes, insulin-like growth factors (IGF1 and IGF2) gene expression were elevated by static incubation with recombinant tilapia SL. In contrast, removal endogenous SL by immunoneutralization using SL antiserum was shown to inhibit IGF1 and IGFgene expression. These findings, taken together, provide evidence for the first time that SL may serve as a novel regulator in fish stimulating IGF1 and IGF gene expression in hepatocytes.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125482073","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 study was conducted in the Turag River starting from Amin Bazar bridge (23°47' N 90°20'E) to Kamarpara bridge (23°53' N 90°23'E). This inventory survey was sampled at a fortnightly interval usually between 7.00 am to 5.00 pm by a team using a boat from December 2012 to November 2013. Detailed information on catch by species, fish length & weight, different types of gear & craft were collected through direct observation. A total of 71 (65 indigenous and 6 exotic) fish species (under 25 families of 9 orders) have been identified. 17 different types of gears of two categories (active and passive gear) and 8 different types of crafts were observed to harvest fish in the study area. The survey revealed that rising floodwater stimulated an increase in fishing activities in the study area from July to October. Fish numbers were recorded lower from November to July (dry and pre-monsoon period) likely due to reduced water flow and adverse water quality of this river. A paired t-test indicate that fish species numbers were significantly difference between Dry and pre-monsoon (P=0.02), Dry and monsoon (P=0.02) and Dry and post-monsoon season (P=0.03) respectively. However, fisheries resources contribution is very limited for livelihood of the surrounding people.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123594775","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}
