Optimisation of mesh enclosures for nursery rearing of juvenile sea cucumbers

Mariculture of tropical sea cucumbers is promising, but the nursery rearing of juveniles is a bottleneck for farming and sea ranching. We conducted four medium-scale experiments lasting 3–6 weeks, using thousands of cultured juvenile sandfish Holothuria scabra, to optimise nursery rearing in mesh enclosures in earthen seawater ponds and to test rearing in enclosures in the sea. The findings and experimental approach should be valuable for optimising mariculture of other tropical sea cucumbers.

A rights-based perspective on adaptive capacity

Whilst it is increasingly recognised that socio-political contexts shape climate change adaptation decisions and actions at all scales, current modes of development typically fail to recognise or adequately challenge these contexts where they constrain capacity to adapt. To address this failing, the authors consider how a rights-based approach broadens understanding of adaptive capacity while directing attention towards causes of exclusion and marginalisation.

Redistribution of water use and benefits among hydropower affected communities in Lao PDR

In this paper, we assess how resettlement and changes in water access have altered livelihoods of local communities upstream of the Theun Hinboun Expansion Project in Lao PDR. Based on household surveys conducted both before and after resettlement, we estimate changes in water use and benefits among households of 4 resettled villages.

Locally-managed marine areas: multiple objectives and diverse strategies

Community-based management and co-management are mainstream approaches to marine conservation and sustainable resource management. In the tropical Pacific, these approaches have proliferated through the spread of locally-managed marine areas (LMMAs). LMMAs have garnered support because they can be adapted to different contexts and focus on locally identified objectives, negotiated and implemented by the people involved.

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.

WorldFish incubator: Investing in sustainable aquaculture through SMEs

WorldFish Incubator bridges the gap between scientific research and business by supporting investment in sustainable small- and medium-sized aquaculture enterprises in Africa, Asia and the Pacific. By building opportunities for growth, WorldFish Incubator connects small-scale aquaculture enterprises in Africa, Asia and the Pacific with investors seeking scalable, high-impact, bottom-line investments in aquaculture.

When co-management fails: a review of theory and lessons learned from reservoir fisheries in dry-zone of Sri Lanka

Over recent decades co-management has become an increasingly popular form of governance reform in many developing countries. Viewed as a means of promoting sustainable and equitable management of natural resources, it has seen wide application in small-scale inland fisheries. However, perhaps because of its worthy credentials, there has been insufficient critical assessment of the results. This paper commences with a review of underlying theory which is then used to explore the reasons for failure of a co-management initiative in Sri Lankan reservoir fisheries between 2001 and 2002.

Weather Index Insurance: Lessons Learned and Best Practices for Bangladesh Workshop Report, 8-9 September 2013, Dhaka, Bangladesh

WorldFish and the International Centre for Climate Change and Development (ICCCAD) held a two-day workshop on the topic of Weather Index-Based Insurance: Lessons Learned and Best Practices for Bangladesh. Weather index insurance is based on a predefined weather event which when triggered ensures automatic payout to farmers who have taken out insurance. For example, the climatic trigger could be a predefined consecutive number of days where rainfall is below a set level or when the floodwater level reaches above a certain point.
