The aim of the present study was to detect heavy metals content from the gills of L. rohita H., C. catla H., and C. mrigala H., respectively, from Keenjhar Lake water and to evaluate the histological alterations from the gills, due to the accumulation of waterborne toxicants. Heavy metals content was detected via flame atomic absorption spectrometer (FAAS) and electro thermal atomic absorption (ETAAS). The pathologic lesions of the gills included hypertrophy, hyperplasia, fusion of secondary gill lamella, aneurism, hemorrhage, vascular congestion, proliferation, dislocation, hyperemia, and deformities of gill arches. The gills of C. mrigala H. showed extensive range of histological alterations, even elevated heavy metals burden. Heavy metal content from the gill of C. mrigala H. were 3.29, 4.25, 4.57, 4.06, 97.68, 75.06, 10.11, 10.36, and 11.09 μ g g− 1 dry weight for Cd, Ni, Zn, Pb, Fe, Ca, Cu, Cr, and Co, respectively. Heavy metals content exhibited in Keenjhar Lake water was in descending order as Ca < Cu < Fe < Zn < Co < Cr < Pb < Ni < Cd; however, Zn, Pb, and Co were higher than permissible limits, while the rest of the elements were below than those of permissible limits recommended by the World Health Organization. Heavy metal content from the gills of cyprinids was variable.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903430522","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679813","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}

Moreover, there are growing doubts as to the long-term sustainability of many existing food production systems, including capture fisheries and aquaculture, to meet the future increasing global demands. Of the different agricultural food production systems, aquaculture (the farming of aquatic animals and plants) is widely viewed as an important weapon in the global fight against malnutrition and poverty, particularly within developing countries where over 93% of global production is currently produced, providing in most instances an affordable and a much needed source of high quality animal protein, lipids, and other essential nutrients. The current article compares for the first time the development and growth of the aquaculture sector and capture fisheries by analyzing production by mean trophic level. Whereas marine capture fisheries have been feeding the world on high trophic level carnivorous fish species since mankind has been fishing the oceans, aquaculture production within developing countries has focused, by and large, on the production of lower trophic level species. However, like capture fisheries, aquaculture focus within economically developed countries has been essentially on the culture of high value-, high trophic level-carnivorous species. The long term sustainability of these production systems is questionable unless the industry can reduce its dependence upon capture fisheries for sourcing raw materials for feed formulation and seed inputs. In line with above, the article calls for the urgent need for all countries to adopt and adhere to the principles and guidelines for responsible aquaculture of the FAO Code of Conduct for Responsible Fisheries.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903325680","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679727","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}

Johnson, David Welch","doi":"10.1080/10641260903434557","DOIUrl":"https://doi.org/10.1080/10641260903434557","url":null,"abstract":"Marine capture fisheries are an important source of protein globally, with coastal and oceanic fish providing a rich source of essential fatty acids, vitamins, and minerals. Fisheries also support economies and important social structures in many nations, particularly developing nations (Allison et al., 2009). Marine fisheries are under increasing threat from climate change, with climate change now identified as the latest threat to the world's fast declining fish stocks (UNEP, 2008; Cochrane et al., 2009). Marine fisheries will be exposed to increasing sea surface temperatures, ocean acidification, sea level rise, increasing storm intensity and altered ocean circulation, and rainfall patterns that will affect target species through a range of direct and indirect mechanisms. The sensitivity of fish stocks to these changes will determine the range of potential impacts to life cycles, species distributions, community structure, productivity, connectivity, organism performance, recruitment dynamics, prevalence of invasive species, and access to marine resources by fishers. Many fisheries are already experiencing changes in target species diversity and abundance, species distribution, and habitat area, as well as loss of fishing effort due to intensifying storms (Johnson and Marshall, 2007; Hobday et al., 2008; UNEP, 2008). Using a vulnerability assessment framework, we examine the level of vulnerability of marine fisheries to climate change and the factors that will temper vulnerability, such as adaptive capacity. Assessing fisheries vulnerability to climate change is essential to prioritize systems in greatest need of intervention, understand the drivers of vulnerability to identify future research directions, and more importantly, to review current fisheries management with the view to develop management responses that will be effective in securing the future sustainability of marine fisheries.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903434557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679891","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}

For this objective, two multivariate analysis techniques, namely canonical correlation analysis and multivariate multiple linear regression analysis, were used. The results of the canonical correlation analysis have shown that the morphological traits may be used to predict the changes in the reproductive traits. For instance, canonical correlation analysis results suggested that the egg weight and the number of eggs are related to the total length, carapace length, and carapace width. The results of multivariate multiple linear regression analysis, on the other hand, show a slightly different picture. Therefore, it is possible to conclude that both canonical correlation and multivariate regression results can be taken into consideration together when investigating the relations between two variable sets.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903491003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679952","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}

We correct and explain problems in the literature in updating these checklists, including 64 confusions, 63 synonyms used, 51 omissions, 14 errors, 13 stomach contents called parasites, 9 incorrect species, 7 nomen nudums used, 7 incorrect higher classifications, 6 false hosts, and resolve the old controversy of Bathycotyle branchialis/B. coryphaenae preferred location in the gills, but not of its identity, the identity of Benedenia hendorffii, nor the mysterious rarity of Echinophallus lonchinobothrium and Plicocestus janickii. Most of the known parasites of dolphins actually rarely occur on these hosts. Dinurus hippurus, D. ivanosi, Floriceps saccatus, Metabronema magna, and Pennella sp. occur in limited geographic areas. However, 14 species of parasites occur commonly in the Dolphin and 5 in the Pompano Dolphin around the world. Charopinopsis quaternia is almost host specific and a characteristic parasite; Hysterothylacium pelagicum is genus specific and characteristic; Dinurus barbatus, D. breviductus, D. hippurus, D. longisinus, and D. tornatus are characteristic; Caligus quadratus, Hirudinella ventricosa, and Tetrochetus coryphaenae are primary parasites; Bathycotyle branchialis (or B. coryphaenae), Benedenia hendorffii, and Stephanostomum coryphaenae are host specific to the Dolphin; Pennella sp. is genus specific to dolphins. The Dolphin is the preferred host of Euryphorus nordmanni, a preferred host of Lernaeenicus longiventris, and dolphins are preferred hosts of Caligus coryphaenae. Rhadinorhynchus pristis is a secondary parasite. Caligus quadratus and Kudoa thyrsites may, and Neobenedenia melleni and M. pargueraensis will cause problems in Dolphin aquaculture. Only nine species of parasites have been shown to harm the Dolphin in nature, but this area is largely unknown. More dolphin parasites are known from the NW Atlantic, but this is study bias, not reality. Dolphins appear to be parasitologically isolated from other families of fishes. The distributions of some Dolphin parasites suggest this worldwide host may be separated into populations that have little communication.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903295909","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679684","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}

Accordingly, fish distributions have been studied for nearly three decades. These studies, however, have not been integrated and summarized in a single body of work to determine overall patterns in the spatial distribution of emigrants. We reviewed peer-reviewed and gray literature to summarize species-specific trends in the horizontal and vertical distributions of emigrating salmonids as measured by several different methods. We found that there were no species-specific differences in horizontal distributions and that fish were often oriented with the river thalweg. There were weak differences between species in vertical distributions, e.g., juvenile yearling steelhead were shallower during the day than yearling Chinook salmon. For sockeye, coho, and subyearling Chinook salmon, the data were limited or conflicting. Studies were purposefully designed to measure distributions at certain dams under particular environmental conditions for specific, local purposes. The non-standard sampling design has hampered the development of testable hypothesis on fish distributions in the Snake and Columbia rivers. Recent advances in individual-based models are offering the potential to forecast fish distributions near dams and facilitate improved bypass system design.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903304487","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679692","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 only known native (indigenous) freshwater crayfish species of Turkey is A. leptodactylus. It is found at more sites than A. torrentium. On the other hand, A. torrentium is only found in Thrace region of Turkey. The first population of A. torrentium was observed in Velika River in 1995. In 2006, the second population of A. torrentium was found in Madara Brook in the region, but the abundance of A. torrentium in Madara Brook was very low in comparison to Velika River. Moreover, further studies carried out in some water resources near the population of A. torrentium, such as De[vgrave]irmen Brook, Poyralı Brook, and Hasköy Brook confirmed that no other populations of this species are present in the region at present. Therefore, it can be concluded that A. torrentium is only present in the northwest of Marmara river basin (Istaranca Mountain Part) and A. leptodactylus is widely distributed throughout the places located to the south of Marmara river basin, and Istaranca Mountain might be a border line that separates A. leptodactylus and A. torrentium populations. Moreover, except the presence of these two species, no other crayfish species are found in the Thrace region of Turkey at present.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903267445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679647","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}

Swamp eel feed on a wide variety of organisms, the most common of which are small fishes, crustaceans (mostly crayfish), and insects. In a laboratory study, swamp eel died at temperatures ≤8°C. No deleterious ecological effects associated with the swamp eel's presence were detected during the 11 years we studied this species, nor was there any evidence that it makes overland movements. Based on these data and observations, the swamp eel in Florida is best described as an illegally introduced, opportunistic and successful predator that feeds on a variety of small prey; fortunately, however, it is unlikely to perpetrate major ecological or economic disturbances.","PeriodicalId":49627,"journal":{"name":"Reviews in Fisheries Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10641260903225542","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59679636","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}
