Determinants of small-scale fishermen's income on Oman's Batinah Coast

The small-scale fishing industry of Oman is responsible for almost 90 percent of the total marine fishery production. It is also the main supplier of fish for Omani households. This study analyzes the factors that determine small-scale fishermen’s income on Oman’s Batinah Coast, which has almost 30 percent of Oman’s population and more than one-third of the small-scale fishermen. We find that fishermen’s income here can be explained broadly under four major blocks of variables: geographical region, fishing inputs and catch, socioeconomic and demographic characteristics, and the nature of the relationship with fisheries extension services. In general, the Wilayat (local administrative units) failed to make any significant impact on fishermen’s income. The variable “Fishing inputs and catch,” such as increases in engine power, boat length, weekly catch, and number of weekly trips, positively impacted fishermen’s income while increases in weekly fishing costs, number of crew members, and difficulty in getting ice had a significantly negative effect on the income. Furthermore, socioeconomic and demographic characteristics also contributed significantly in determining the fishermen’s income level. The other important findings were related to extension services. The variables “Fishermen’s exchange of information and cooperation with the ministry” and “Fishermen’s involvement in the extension activities” were found to have positive effects on fishermen’s income levels. Capitalizing on these findings could improve fishermen’s incomes and their lives across the region, as well as nationally.

Small-scale spatial and temporal variability in growth and mortality of fish larvae in the subtropical northcentral Gulf of Mexico: implications for assessing recruitment success

Extensive plankton collections were taken during seven September cruises (1990–93) along the inner continental shelf of the northcentral Gulf of Mexico (GOM). Despite the high productivity and availability of food during these cruises, significant small-scale spatial variability was found in larval growth rates for both Atlantic bumper (Chloroscombrus chrysurus, Carangidae) and vermilion snapper (Rhomboplites aurorubens, Lutjanidae). The observed variability in larval growth rates was not correlated with changes in water temperature or associated with conspicuous hydrographic features and suggested the existence of less-recognizable regions where conditions for growth vary. Cruise estimates of mortality coefficients (Z) for larval Atlantic bumper (n=32,241 larvae from six cruises) and vermilion snapper (n= 2581 larvae from four cruises) ranged from 0.20 to 0.37 and 0.19 to 0.29, respectively. Even in a subtropical climate like the GOM, where larval-stage durations may be as short as two weeks, observed variability in growth rates, particularly when combined with small changes in mortality rates, can cause order-of-magnitude differences in cumulative larval survival. To what extent the observed differences in growth rates at small spatial scales are fine-scale “noise” that ultimately is smoothed by larger-scale processes is not known. Future research is needed to further characterize the small-scale variability in growth rates of larvae, particularly with regard to microzooplankton patchiness and the temporal and spatial pattern of potential predators. Small-scale spatial variability in larval growth rates may in fact be the norm, and understanding the implications of this subtle mosaic may help us to better evaluate our ability to partition the causes of recruitment variability.

Asserting rights, defining responsibilities: perspectives from small-scale fishing communities on coastal and fisheries management in Cambodia

In preparation for the Workshop and Symposium on “Asserting Rights, Defining Responsibilities: Perspectives from Small-scale Fishing Communities on Coastal and Fisheries Management in Asia”, held in Siem Reap Cambodia, from 3 to 8 May 2007, case studies were undertaken in six countries in Asia—Bangladesh, Cambodia, India, Indonesia, Philippines and Thailand. Among other things, the studies aimed to document and explore the understanding that fishing communities have about their rights to fisheries and coastal resources, as well as the obligations and responsibilities associated with these rights, and to document and discuss their initiatives to assert these rights and fulfill their responsibilities. The studies formed the basis for discussions at the Workshop and Symposium. This case study from Cambodia will be found useful by NGOs, regional and national organizations of artisanal fishworkers, and anyone interested in fisheries and fishing communities in Cambodia.

Marine protected areas and small-scale fisheries in South Africa: promoting governance, participation, equity and benefit sharing

This monograph studies the progress achieved by conservation partners in South Africa on the implementation of the Convention on Biological Diversity (CBD) Programme Element Two components of governance, participation, equity and benefit sharing, from the perspective of small-scale fishing communities. It explores the strategies and mechanisms used by different authorities to create the conditions whereby local communities can benefit from marine protected areas (MPAs), of which South Africa has gazetted 24, highlighting examples of best practice. The monograph will be useful for researchers, scientists, fishworker organizations, environmentalists and anyone interested in the protection of marine biodiversity and the promotion of sustainable fisheries management.
