Traditional institutions and their role in the contemporary coastal resource management in the Pacific Islands

A discussion is presented on the role played by customary marine tenure (CMT) institutions in the regulation of fisheries in the Pacific Ocean Islands. Particular reference is made to the system in operation in Marovo Lagoon, in the Solomon Islands, whereby a number of defined clans control resource use within defined areas of land and sea. It is believed that such systems have considerable capacity for handling and adapting to new circumstances, thereby becoming potentially important tools in the contemporary management of fisheries and of the coastal zone in general.

Checklist of the shore fishes of the Mentawai Islands, Nias Island and the Padang Region of West Sumatra

This paper presents a checklist of reef fishes of West Sumatra and adjacent provinces. The list includes 362 species of 143 genera and 46 families and contains seven new records and nine probable new species for Indonesia. It also uses information from sources only available in Bahasa Indonesia. The relative paucity of the fish fauna in West Sumatra seems to be related to the habitat destruction caused by illegal fishing with explosives or poisons such as cyanide.

Length-weight relationship of fishes and cephalopods from the Balearic Islands (Western Mediterranean)

Length-weight relationship (LWR) parameters of 72 species of fishes and 15 species of cephalopods caught in the Balearic Islands demersal fishery are reported. This is the first compilation of LWR for these groups in the Balearic Islands.

Low cost light traps for coral reef fishery research and sustainable ornamental fisheries

Two relatively inexpensive light traps to capture pre-settling reef fish and invertebrates are described. A trap made from a plastic bucket (with plastic bottles, a small plastic waste bin and two sheets of plywood) that costs US$15 appears to be just as effective as a large aluminium and plexiglass trap that costs US$275.

Temporal and Spatial Distribution of Catches of Tiger Sharks, Galeocerdo cuvier, in the Pelagic Longline Fishery Around the Hawaiian Islands

Thirty-five tiger sharks, Galeocerdo cuvier, have been reported caught in pelagic longline gearfrom 25 to 265 n.mi. off the Hawaiian Archipelago during December 1990-May 1993. Fifteen sharks were caught farther than 50 n.mi. offshore, indicating that tiger sharks do occur well offshore and removed from benthic topography. About 89% of the sharks were caught during October-March, while only 56% of the fishing effort occurred during that period.

The Fisheries of Hawaii and U.S.-associated Pacific Islands

In the late 1980's and early 1990's, significant changes occurred in the fisheries of Hawaii. Expansion and diversification of pelagic fisheries and growth (including industrialization) of fisheries that, in at least some cases, had been largely recreational or artisanall ed to fear of overfishing and problems in allocation among fishery sectors. Combined with establishment of limited entry programs in Hawaii fisheries (bottomfish, longline, and lobster), this led to anticipation that similar growth might occur in Guam, the Northern Marianas, and American Samoa.

Fisheries and Marine Resources of Hawaii and the U.S.-associated Pacific Islands: An Introduction

The fisheries of Hawaii and other U.S.-associated islands in the Pacific Ocean are characterized by high diversity, both in the species exploited and the human cultures that exploit them. The commercial sector has undergone rapid growth in recent years, but recreational and subsistence sectors remain important. Information on these fisheries is generally not available in published form. This paper presents an overview and introduction to a volume of papers describing fisheries in the region, with the goal of making the information available to scientists and the general public. A great deal remains to be learned about the dynamics of these fisheries as well as the associated issues in biological research, fisheries management, and environmental protection.

On the Distribution and Fishery Potential of the Japanese Red Crab Chaceon granulatus in the Palauan Archipelago, Western Caroline Islands

A deep-water trapping survey in the Palauan archipelago, Western Caroline Islands, has revealed an abundance of the Japanese red crab, Chaceon granulatus. The recorded depth range (250-900 m) is similar to that of other geryonids, but the large numbers of females caught below 700 m is atypical. Mean yields in excess of 5 kg crabs plus 1 kg shrimp, Heterocarpus laevigatus, by-catch per trap-night were attainable at optimum depths. Chaceon granulatus is apparently a very large geryonid, with maximum weights of 2.02 kg and 1.51 kg recorded for male and female specimens, respectively. A range of body colors was observed: Orange-red shades appear to dominate the deeper waters (below 500 m) while yellow-tan colors are more abundant in the upper reaches. Preliminary evidence suggests that Chaceon granulatus is highly marketable, and the infrastructure in Palau is such that crabs could either be marketed fresh locally or airfreighted to Japan as a quick-frozen product. The high post-trapping survival rates observed indicate that maintaining crabs in live-holding tanks may be a feasible option. The large catches and quality of deep-water crabs taken suggests that the Palauan population of Chaceon granulatus may be able to support a small-scale fishery. It is not yet known whether this population is unusually large or whether these findings typify the deep forereef fauna of the region.

Application of the Leslie Model to Commercial Catch and Effort of the Slipper Lobster, Scyllarides squammosus, Fishery in the Northwestern Hawaiian Islands

Commercial catch and effort data were fit to the Leslie model to estimate preexploitation abundance and the catchability coefficient of slipper lobster, Scyllarides squammosus, in the Northwestern Hawaiian Islands (NWHI). A single vessel fished for 34 consecutive days in the vicinity of Laysan Island and caught 126,127 total slipper lobster in 36,170 trap hauls. Adjusted catch of legal slipper lobster dropped from a high of 3.70 to 1.16 lobster per trap haul. Preexploitation abundance at Laysan Island was an estimated 204,000 legal slipper lobster, which was extrapolated to yield an estimate of 1.2 X 106 to 3.8 X 106 lobster for the entire NWHI slipper lobster fishery.

Structure and development of a Scalesia pedunculata stand in the Galapagos Islands

Stands of Scalesia pedunculata in the Galapagos Islands often develop as single-aged cohorts following episodes of mass death and regeneration. We updated earlier studies on a stand that had regenerated soon after the 1982–3 El Niño event. We quantified stem size distribution and dispersion pattern in a 0.56 ha plot near Los Gemelos on Santa Cruz Island. The plot was dominated (95% of basal area) by S. pedunculata. The stem size distribution showed the increased mean and variance for diameter (since 1987 and 1991) expected of an aging stand. Stems averaged smaller than in 1981, just before the last mass mortality episode. Large S. pedunculata stems were regularly dispersed while smaller stems were clumped and negatively associated with larger stems, implying that intraspecific competition may be important in structuring the stand.

The distribution, conservation, and larval food plant of Epiplema becki Hayes (Insecta: Lepidoptera: Uraniidae) on the Galapagos Islands

Two new populations and the host plant of the rarely encountered Galapagos endemic moth Epiplema becki were found on Isabela Island, on Wolf and Sierra Negra volcanoes, with a sighting on Darwin Volcano. The host plant is the native Duranta dombeyana (Verbenaceae). The habitats where all known specimens were collected were Scalesia forest with Duranta bushes. To ensure the conservation of E. becki, we recommend control of introduced species in its habitat. CDF Contribution Number 1010.

Food and nutrition security in Solomon Islands

This report is a literature review on Food and Nutrition Security in Solomon Islands, based on data from surveys conducted by Solomon Islands National Statistical Office, as well as from national and international organizations working in Solomon Islands. The purpose of the report is to present information outlining the current food and nutrition situation in Solomon Islands before implementation of the CGIAR Research Program on Aquatic Agricultural Systems (AAS), led by WorldFish. The aim of the AAS program is to enhance production in natural freshwater and/or coastal ecosystems to improve household livelihood, including income and food security. This report summarizes national statistics and also focuses in more detail on a subset of provinces: Guadalcanal, Malaita and Western. In 2012, the AAS program was rolled out in Guadalcanal, Central and Malaita Provinces, designated the Central Hub. In 2013, roll out is beginning in the Western Hub (Western and Isabel Provinces). The priority province for the Central Hub has been identified as Malaita.
