Reproductive season of the Caribbean spiny lobster Panulirus argus in the coastal waters of northern Brazil

The spawning season of the Caribbean spiny lobster Panulirus argus (Latreille) was identified based on adult specimens collected monthly off northeastern Brazil, from August 1982 to July 1988. The maturity indices used were relative abundance of females with full spermatheca, eggs or rests of spermatheca, female gonad weight and relative abundance of stage four females. The main spawning activity occurs in February to May, with an occasional second peak in September/October.

A preliminary assessment of the coastal fishery resources in India: socioeconomic and bioeconomic perspective

India is endowed with a continental shelf of 0.5 million km2 and an exclusive economic zone (EEZ) of about 2 million km2. Almost half (39%) of the Indian population utilizes the marine fisheries resources. India ranked sixth worldwide in total fish production (4.95 million t) and second in inland fish production (2.24 million t) during 1995 - 96. Fish production expanded from 0.75 million t in 1950 - 51 to 4.95 million t in 1995 - 96, giving a significant increase at a cumulative growth rate of 4.2% per annum.

A preliminary analysis on the socioeconomic situation of coastal fishing communities in Vietnam

Fish production in Vietnam increased rapidly from 420 000 t in 1981 to 1 130 680 t in 1998. Likewise, there was an expansion in the number of motorized fishing boats from 29 584 units with an average horsepower (HP) of 19.8 boat-1 in 1981 to 71 800 units with an average HP of 26.2 in 1998. In 1995, fish production was valued at VN$2 475 billion (US$0.02 billion at 1 US$ = 11 041 VN$; source: oanda. com).

Phylogeography of a pearl oyster (Pinctada maxima) across the Indo-Australian Archipelago: evidence of strong regional structure and population expansions but no phylogenetic breaks

This study investigates the genetic structure and phylogeography of a broadcast spawning bivalve mollusc, Pinctada maxima, throughout the Indo-West Pacific and northern Australia. DNA sequence variation of the mitochondrial cytochrome oxidase subunit I (COI) gene was analysed in 367 individuals sampled from nine populations across the Indo-West Pacific.

Paralegal work: a community-based approach to fisheries law enforcement ni Negros Occidental, Philippines

The depletion and degradation of the State marine and aquatic resources due to uncontrolled exploitation are the primary reasons for the enactment of fisheries laws. There are two approaches to the enforcement of these laws. Traditional law enforcement involves the intervention or actual performance by government through its designated and deputized agents. However, government activities are directed mainly at preventing further resource depletion. This is a shortcoming that prompted the conduct of alternative law enforcement strategies aimed at resource development.

An overview of the socioeconomic status of fisheries in Malaysia

Fish production in Malaysia increased steadily at 4.5% per annum from 801 000 t in 1985 to 1 280 906 t in 1997. Most of the production was contributed by marine capture fisheries, amounting to 1 168 973 t (91% of total production) in 1997, while the rest (132 700 t or 8%) came from inland fisheries and aquaculture. About 72% of the marine landings, or 837 574 t, were from Peninsular Malaysia while the rest were from the states of Sabah, Sarawak, and the Federal Territory Labuan.

Overview of the national fisheries situation with emphasis on the demersal fisheries off the west coast of Peninsular Malaysia

The marine fisheries sector in Malaysia contributes significantly to the national economy in terms of income, foreign exchange and employment. In 1999, marine fisheries contributed 1.245 million t (90% of total fish production) valued at US$1.18 billion. The total value accounted for about 1.53% of national GDP and 11.31% of agricultural GDP. The export of fish and fishery products amounted to about US$210 million. The sector provided employment to about 80 000 fishers. Fisheries management is currently guided by the Third National Agricultural Policy (NAP3 1998 - 2010).

Overfishing and the replacement of demersal finfish by shellfish: An example from the english channel

The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure of marine ecosystems. Here we assess changes in the trophic structure of the English Channel marine ecosystem using a 90-year time-series (1920–2010) of commercial fishery landings. Our analysis was based on estimates of the mean trophic level (mTL) of annual landings and the Fishing-in-Balance index (FiB).

Marine Protected Areas in the Coral Triangle: Progress, Issues, and Option

The six Coral Triangle countries-Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands, and Timor-Leste-each have evolving systems of marine protected areas (MPAs) at the national and local levels. More than 1,900 MPAs covering 200,881 km2 (1.6% of the exclusive economic zone for the region) have been established within these countries over the last 40 years under legal mandates that range from village level traditional law to national legal frameworks that mandate the protection of large areas as MPAs.
