Understanding leadership in the environmental sciences

Leadership is often assumed, intuitively, to be an important driver of sustainable development. To understand how leadership is conceptualized and analyzed in the environmental sciences and to discover what this research says about leadership outcomes, we conducted a review of environmental leadership research over the last 10 years. We found that much of the environmental leadership literature focuses on a few key individuals and desirable leadership competencies.

Lessons for resource conservation from two contrasting small-scale fisheries

Small-scale fisheries present challenges to management due to fishers’ dependency on resources and the adaptability of management systems. The authors compared social-ecological processes in the sea cucumber fisheries of Zanzibar and Mayotte, Western Indian Ocean, to better understand the reasons for resource conservation or collapse.

The contribution of nearshore fish aggregating devices (FADs) to food security and livelihoods in Solomon Islands

Fish aggregating devices, or FADs, are used widely in developing countries to concentrate pelagic fish, making them easier to catch. Nearshore FADs anchored close to the coast allow access for rural communities, but despite their popularity among policy makers, there is a dearth of empirical analysis of their contributions to the supply of fish and to fisheries management. In this paper the authors demonstrate that nearshore FADs increased the supply of fish to four communities in Solomon Islands.

Are trunk lateral line anomalies and disoriented scale patterns in European seabass (Dicentrarchus labrax) influenced by genetics?

Different kinds of defects are observed on farmed fish, and while a lot of research has concentrated on skeletal abnormalities, little is known on scale anomalies. In this paper, a survey for lateral line shape anomalies and disoriented scale patterns was carried out in a common garden experiment involving crosses of 5 different wild populations of European seabass, in order to find if any correlation exists between lateral line shape anomalies, disoriented scale patterns and genetic origin.

Fish for nutrition

More than 2 billion people worldwide, particularly in developing countries, are estimated to be deficient in micronutrients, including vitamin A, iron and zinc. These vitamin and mineral deficiencies are a form of undernutrition affecting children and pregnant women. This fact sheet outlines the key benefits of eating fish, a source of micronutrients and essential acids, in alleviating nutrient deficiency.

Year 1 operational report: Improving employment and income through development of Egypt’s aquaculture sector (IEIDEAS) project

Implementation of the SDC funded project ‘Improving Employment and Income through Development of Egypt’s Aquaculture Sector’ commenced on 1st December 2011 and will continue until late 2014. This report summarizes the results of the first 10 months until 30th September 2012. The project was based on a value chain analysis carried out by WorldFish in September 2011. The information in the VCA acts as the baseline for the main project parameters.
