Details are given of techniques to be used in the handling of large amounts of data in the field of aquaculture. Two examples are given where different types of multivariate data analyses are performed on the compiled datasets to identify and quantify the effects of key variables governing growth and production of fish in manured pond systems cultivating tilapia and carp.
Lake Victoria fisheries face severe environmental stresses. Stocks are declining in a context of increasing population and growing demand for the lake’s resources. Rising competition between users is putting conservation goals and rural livelihoods at risk. While Uganda’s co-management policy framework is well-developed, key resources for implementation are lacking, enforcement is poor, and the relations between stakeholders are unequal. Poor rural resource users face significant challenges to effectively participate in fisheries decision-making.
These publications, consisting of a Regional State of the Coral Triangle report with six corresponding country-level State of the Coral Triangle reports, identify key issues that decision makers must address if sustainable development of the Coral Triangle’s coastal and marine resources is to be achieved. The Regional State of the Coral Triangle report summarizes each country’s biophysical and socioeconomic characteristics, as well as their institutional framework for governing marine resource use.
The Coral Triangle is a global priority for conservation and since the creation of the Coral Triangle Initiative in 2007 it has been a major focus for a multi-lateral conservation partnership uniting the region's six governments. The Coral Triangle (CT) Atlas was developed to provide scientists and managers with the best available data on marine resources in the Coral Triangle.
The recent transition, in Italy, to an improved sampling scheme for fisheries catch and effort data, is described, with emphasis on the interactions between civil servants and fisheries scientists and on specific features of Italian fishery resources and research that may be common with those of some developing countries.
Bangladesh has an exclusive economic zone (EEZ) of 164 000 km2 and a continental shelf area of 66 440 km2. Artisanal (small scale) fisheries extend from the coast to 40 m while industrial (commercial scale) fisheries operate beyond 40 m depth. The coastal fisheries of Bangladesh exploit a complex multi-species resource. There are 18 demersal and pelagic species, seven species of larger pelagic and 10 shrimp species that are commercially important among the fishes exploited.
This brief focuses on the potential for the social-ecological systems (SES) framework to engage with concerns about gender and social change. It specifically considers how far feminist political ecology (FPE) can address its shortcomings.
This paper was prepared by a group of authors of complementary experiences and presented during the Thematic Session V: Improving knowledge and information sharing, research and extension in aquaculture at the Global Conference on Aquaculture 2010, Farming the Waters for People and Food held in Phuket, Thailand on 22–25 September 2010.
The current study was designed to optimize the dietary levels of Spirulina platensis in Oreochromis niloticus; this was tested via graded levels. Six isonitrogenous and isocaloric rations containing graded levels of dried spirulina 0, 5, 7.5, 10, 15 and 20 g/kg diet were fed separately to six equal groups of O. niloticus fingerlings for 3 months. Growth performance, non-specific immune parameters, tissue reactions and resistance of tilapias post challenge infection with Pseudomonas fluorescens were estimated monthly.
Rock lobsters have been known to exist in the Aden Gulf since 1962, but the commercial catches of this valuable resource began in 1975. This short article gives an account of rock lobster fisheries in Yemen.
