 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Systematic Data Collection on and Status of Thai Industrial Tuna Purse Seine Operations in the Indian Ocean) ผู้เขียน: Praulai Nootmorn,  ดร.ศรัณย์ เพ็ชร์พิรุณ, รองศาสตราจารย์ , Kanokwan Maeroh สื่อสิ่งพิมพ์:pdf AbstractSix 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. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : An Evaluation on Economic Loss from Luring Purse Seine Fishery in the Gulf of Thailand) ผู้เขียน:ปวโรจน์ นรนาถตระกูล สื่อสิ่งพิมพ์:pdf AbstractSize of 14 commercial pelagic species, income and economic loss were studied from luring purse seine fisheries in the Gulf of Thailand during June 2004 – May 2005 by collecting the data at Samut Prakan fishing port. The average lengths of 12 commercial pelagic species were smaller than the size at first maturity. Income from total commercial pelagic species was 6,533,716.50 baht/boat/year and was 5,301,155.70 baht/boat/year for commercial pelagic species which size smaller than the size at first maturity. An evaluation on economic losses of pelagic species were estimated by comparing the economic value of species which size smaller than the size at first maturity and the size at first maturity. By using an average price at fishing port for evaluation, the economic loss was 184,861.40 baht/boat/ trip or 5,545,842.15 baht/boat/year. If an average price derived from two important markets under Fish Market Division was used for evaluation, the economic loss was 357,262.75 baht/boat/trip or 10,717,882.49 baht/boat/year. The economic loss from luring purse seine fishery in the Gulf of Thailand was 2,700 million baht based on the number of fishing boat registered by luring purse seine gear in 1992. |
