Abstract

Thai tuna longliners were operating in the Indian Ocean from 2000 to 2006; data from their logbooks displayed important information of their fishing operation. Total annual catches during the period were: 384.90, 390.93, 93.57, 252.48, 272.41, 280.12 and 414.44 tonnes, with a value of 2, 1.84, 0.46, 1.16, 1.58, 0.98 and 2.42 million USD, respectively. Fishing grounds were in four zones namely: the Bay of Bengal, the west coast of Indonesia, Somalia and the Seychelles, and the southern part of the Indian Ocean. The highest catch rate was found in Somalia and the Seychelles (1.3 fish/100 hooks), followed by the west coast of Indonesia (1.2 fish/100 hooks) and the southern part of the Indian Ocean (1.0 fish/ 100 hooks). The lowest catch rate was reported in the Bay of Bengal (0.7 fish/100 hooks), which compared to other fishing grounds. The major catch species were bigeye tuna (Thunnus obesus), yellowfin tuna (T. albacares), albacore tuna (T. alalunga), and swordfish and other large pelagic species comprising 36.64, 35.77, 20.28 and 7.31% of the total seven-year catch, respectively. Bigeye tuna were caught in all fishing grounds, with the highest catch in the southern part of the Indian Ocean. Yellowfin tuna occurred in all fishing grounds. However, the highest abundance was found in Somalia and the Seychelles, while the lowest numbers were found in the Bay of Bengal. Albacore tuna were dominant in the southern part of the Indian Ocean. Other large pelagic species recorded included: swordfish (Xiphias gladius), sharks, blue marlin (Makaira mazara), black marlin (M. indica), striped marlin (Tetrapturus audax) and sailfish (Istiophorus spp). Thai tuna longliners fished north of equator during 2000 to 2002 and moved south of the equator during 2003 to 2006. Analysis of catch data by the PRIMER program showed changes in target species from yellowfin tuna, bigeye tuna, swordfish and other species during 2000 to 2002 to albacore tuna, bigeye tuna, yellowfin tuna, swordfish and other species during 2003 to 2006.

Abstract

Six Thai industrial tuna purse sein fishing vessels operated in the Indian Ocean from 2005 to 2006. Fishery information and logistical data were gathered from log books, port sampling and interviews to create a systematic diagram of data collection and processing. The results will be used to support and implement responsible fishery operations under a resolution of the Indian Ocean Tuna Commission. The total catch reported was 12,216 metric tonne (tonne) in 2005 and 23,161 tonne in 2006, with the main fishing ground being off Somalia and the main fishing practice was with associated schools. The highest values for catch data, catch per unit effort (CPUE) and the number of sets were obtained during February to April and September to November in 2006. The monthly catch, CPUE and number of sets ranged from 383-4539 tonne, 15 to 61 tonne/set and 15 to 144 sets, respectively. Skipjack tuna was the main target fish, followed by bigeye tuna, yellowfin tuna and bonito. Skipjack tuna made up a high proportion of the catch during March to September, while bigeye and yellowfin tuna made up a high proportion from September to December 2005 and from January to February in 2006. The size range of skipjack, bigeye and yellowfin tuna varied from 39-75, 45-133 and 33-152 cm, respectively, whilst the length of 50% of capture fish was 60, 66 and 81 cm, respectively. Most of the bigeye and yellowfin tuna were juvenile. The status of bigeye tuna from tuna purse seine fishing was stable in terms of catch and CPUE.

Abstract

An investigation of coral reef-fish fauna was performed from December 1976 to January 1978, around Phuket and several small offshore islands in the Indian ocean. Simple fishing methods were applied in the water less than 10 meters deep at mean tide. There were 230 species of 93 genera found in these locations. Collections included 36 families, most of which inhabited coral heads and crevices of the rocky bottom. The fauna, however, was composed of both resident and non-resident forms. The most common residents were from the families: Pomacentridae, Chaetodontidae, Labridae, Serranidae, Acanthuridae and Lutianidae. A complete collection of all the species inhabited the areas investigated was not possible, because of collecting and identification difficulties.
