Aquaculture and food security in Solomon Islands

"Aquaculture and Food Security in the Solomon Islands" (ACIAR Project FIS/2009/061) was formulated to assist the Government of Solomon Islands in better understanding the future demand for aquaculture and particularly to develop a strategy to guide future development of sustainable inland aquaculture to support food security and secure livelihoods for the Solomon Islands in response to rising populations and climate change.

Anthropologist conducts study of skipjack tuna fisheries in Solomon Islands

The working together of the Solomon Islands and Japan on tuna (Katsuwonus pelamis ) industrialization requires cooperation and mutual trust. This must be based on an understanding of history and everchanging socioeconomic climates, which may be obtained from case studies such as that currently being funded by ICLARM and the Rockefeller Foundation on the South Pacific tuna industrialization.

SLODS: slow dissolving standards for water flow measurements

In this study, we report the development of slow dissolving standard (SLODS™), designed to estimate water flow over a lunar period (30 days). To demonstrate the usefulness and validity of this technique, we describe successful preliminary calibrations, large-scale field experiments and the outcome of a detailed comparison with data obtained from clod cards during studies of giant-clam farming in villages in the Solomon Islands.

Reducing the costs of restocking giant clams in Solomon Islands.

On many corals reefs in the Indo-Pacific, the larger species of giant clams (Tridacnidae) have either been eliminated or fished down to the point where the external fertilization of gametes is improbable. In the mid 1980s, several countries, donors, and regional and international research organizations set out to redress this problem by developing technology to propagate juvenile giant clams in hatcheries and re-establish them in the wild.

Low abundances and diversities of benthic faunas of shallow, coastal sediments in the Solomon Islands and their implications for assessing environmental impacts of logging

The diversity and abundance of benthic organisms were examined in relation to logging impacts in Western Province, Solomon Islands. Organisms occupying sediments offshore from the mouths of logged and unlogged streams in two areas were sampled at three depths during a single survey. Overall abundances of organisms were low, and patterns varied between areas.

Growth and survival of the giant clams, Tridacna derasa, T. maxima and T. crocea, at village farms in the Solomon Islands.

In this study, the authors report the results of large-scale grow-out trials for T. crocea, T. maxima and T. derasa at 11 sites in the Solomon Islands over 2 years. During these experiments, we evaluated the influence of environmental variables and husbandry on growth and survival, and used this information to identify optimum growing sites for these giant clams. The authors also used the biological data in a simple economic analysis of growing each species to two different sizes.

Preservation of genetic diversity in restocking of the sea cucumber Holothuria scabra investigated by allozyme electrophoresis

Population genetics analyses should be considered when releasing hatchery-produced juveniles of the sea cucumber Holothuria scabra when spawners from nonlocal populations are used. In New Caledonia, within-region genetic heterogeneity of H. scabra populations (examined through allozyme electrophoresis of 258 animals) indicated high gene flow between nine sites and F<sub>ST</sub> values dOld_ID not deviate significantly from zero.
