dc.descriptionAround the coastal area of Laem Phak Bia, Petchaburi province, bottom crab gillnet targeting blue swimming crab (Portunus pelagicus) is the typical fishing gear that conducted almost whole year in every season. The fishing boat mainly are small scale boat (< 10 GT). The gillnet made from nylon monofilament (PA), 10 cm mesh size, about 0.5 hanging ratio, 12 mesh depth, 450 m/set (1 set connected by 5 net panels). Fisher hauls the net 2-4 sets for 1-2 GT boat while 18-20 sets/operation day for 8-10 GT boat. The head rope made of polyethylene (PE) z twisted, diameter 4 mm, connected to the flag buoys. The plastic float size of 38x10mm, 2.0 m interval. The foot rope tied to anchor or stone weight 5-8 kg, made of polyethylene (PE) z twisted, diameter 3 mm. Sinker size was 10 g, 0.45m interval. Fishers (8-10 GT boat) usually operate the fishing at 2-7 am in the fishing ground of 18-25 m depth with the soaking time of 3-5 days. Some marketable bycatch are flathead lobster (Thenus orientalis), ray, flatfish and horseshoe crab. Statistics on Fishing community production survey by species of fish, shrimp, crab, shellfish, jellyfish, other aquatic animals, the crab species, highest value was 3,624.24 million baht at 21,570 ton. The crab is an important economic fish for Thai fishery. Thailand is under the influence of southwest and northeast monsoon those impact to the fishing activities. The rainy season (May-Oct) is influenced by southwest monsoon while the winter season (Nov-Jan) influenced by the northeast monsoon. This study aimed to compare the catch, income, operation days and fishing ground of a crab gillnet fisher (9 GT boat) between summer and rainy season.en
