Abstract : A total of 180 trawler and 180 gillnet fishing households were interviewed for fishing activities while fish traders/retailers (30) were interviewed for determination of fish channel market. Economic fish species composition was determined through sampling of 30 trawlers and 30 gillnets households. The results showed that trawl and gillnet fishing operated year-round. Fishing voyage of trawl was shorter, 1.9 days in average while fishing voyage of the gillnet has been unchanged. Fishing yield calculated per HP of trawlers (0.895 ton/HP/year) was seven time higher than that of gillnets (0.128 ton/HP/year). The rate of trash fish in trawler and gillnet in this study reduced. The economic efficiency of trawlers and gillnet have been improved. A large proportion of total fishery products was sold to traders/wholesalers and then transported to the processing factories and sold to the retailers in the local markets. Economic fish species from the two fishing activities has shown the typical species catching following types of fishing gears. Inclement weather and lack of capital are two main constrains for the fishing careers.

Abstract : Honeybees are vulnerable to many diseases, such as European foulbrood, chalkbrood, sacbrood, and American foulbrood (AFB). Caused by Paenibacillus larvae, AFB can cause immense damage to the bee industry. Chemicals and antibiotics have long been used to treat these diseases, resulting in pathogen resistance. As an alternative, antagonistic effect of gut bacteria has been focused on. The culture supernatant (CS) from recently isolated gut bacteria from Thai Apis cerena indica (Bacillus sp., Pantoea sp., Azotobacter sp., Klebsiella sp., and Lactobacillus sp.) were screened for their growth inhibitory activity against P. larvae strains 01 and 02 in an agar well diffusion assay. The CS from Azotobacter sp. had the highest growth inhibition against P. larvae strain 02, while the CS from Bacillus sp., Lactobacillus sp., Klebsiella sp., Azotobacter sp. were all active against both strains. This activity was thermotolerant to 90 ºC for 1 h, but 121 ºC nor to proteinase K and RNase A treatment. Furthermore, the CSs from Bacillus sp. and Klebsiella sp. at pH 3, Pantoea sp. at pH 5, Lactobacillus sp. at pH 8 and 10, and Klebsiella sp. at pH 10 showed the highest inhibitory effect against P. larvae strains 01 and 02. However, the CS inhibitory activity at pH 8–10 was less than that at pH 5 (the pH in the bee stomach). Hence, gut bacteria that can potentially inhibit P. larvae growth were obtained from healthy honeybees.
