The Coral Triangle Atlas: An integrated online spatial database system for improving coral reef management

In this paper we describe the construction of an online GIS database system, hosted by WorldFish, which stores bio-physical, ecological and socio-economic data for the ‘Coral Triangle Area’ in South-east Asia and the Pacific. The database has been built in partnership with all six (Timor-Leste, Malaysia, Indonesia, The Philippines, Solomon Islands and Papua New Guinea) of the Coral Triangle countries, and represents a valuable source of information for natural resource managers at the regional scale.

Breeding marine aquarium animals: the anemonefish

A brief account is given of experiments undertaken regarding the breeding of anemonefish (Amphiprion ), a species popular among marine aquarists. Findings indicate these fish to be good candidates for reproductive physiology research; they produce large eggs and larvae, spawn frequently in captivity, are hardly to handle and can be maintained in small tanks. Future prospects for the culture of tropical marine aquarium fish are believed to be good.

Vital statistics of marine fishes of Vanuatu.

Vital statistics are presented for 38 marine species of Vanuatu based on previous studies conducted in the area, with parameters describing growth (6 species, 13 sets of parameters), mortality (estimates of M for 6 species), length-weight relationship (32 species), and reproduction (length at first maturity for 26 species, months of reproduction for 18 species). The species covered belong mainly to the family Lutjanidae.

Length-weight relationships of Cuban marine fishes.

A total of 140 sets of parameters (a and b) of the length-weight relationships (LWR) of the form W=aL super(b) are presented for fishes caught in Cuban waters. These parameters cover 94 species of fish belonging to 43 families. Most of the parameters were compiled from 107 sets of published and unpublished studies. Twenty-five sets of parameters were from personal communications through colleagues in Cuba, while the remaining eight sets were estimated by the authors from unpublished data.

Length-weight relationship of some marine fish species in Reunion Island, Indian Ocean.

The length-weight relationship of 29 marine fish species form Reunion Island (SW Indian Ocean) belonging to 14 families were computed. Data from 5,340 individuals were used for this purpose. Fish were sampled using different techniques, mainly with rotenone poisoning on coral reef flats, beach seine and handlines on shallow coastal bays, and longline fishing in the nearby open sea.

Length-weight relationship of marine fishes from southern Brazil

The relationship between length (L) and weight (W) was estimated for 80 species belonging to 50 families of marine fishes from the shelf and upper slope of southern Brazil (lat. 28°S - 34°S). Sample sizes (n) for different species ranged from 11 to 14 741 specimens collected from commercial landings and research surveys. The fit of the equations (W=aLb) with a and b parameters estimated from regular and functional regression (of log-transformed weight and length data) as well as from a non-linear iterative process using the quasi-Newton algorithm were compared.

Growth performance of Nigerian fish stocks.

Parameters of the von Bertalanffy growth function are presented for 42 fish stocks belonging to 16 families, 22 genera and 27 species. The growth performance index, Phi '(= log K + 2logL sub( infinity )), was computed for each stock and was found to be highest in male Gymnarchus niloticus (Gymnarchidae) from Lake Chad and lowest in Chrysichthys auratus (Bagridae) from the Cross River. Mean Phi ' for major fish genera and families are also presented and was highest in brackishwater fishes, closely followed by freshwater and inshore marine water fishes.

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.
