Abstract
The research finding was investigated the species diversity and population structure of fishes in the Khanom Estuary, Khanom District, Nakhon Si Thammarat Province carried out in November 2016 (the northeast monsoon) and July 2017 (the southwest monsoon) at ten sampling stations. The fish specimens were collected using beach seine and dip-net. A total of 1,406 individuals representing 37 species from 27 families were found. The most dominant family was Gobiidae [5 species (13.5%)], e.g., Acentrogobius viridipunctatus, Acentrogobius caninus, Glossogobius sp., Brachygobius doriae and Gobiopterus chuno followed by Ambassidae with three species (8.1%) and other families with one or two species each. Ambassis kopsii and Gerres filamentosus were mostly distributed in the study area. They were found in brackish water canal ecosystems, estuary ecosystems, and the coastal marine ecosystem. The population structure corrected in November 2016 revealed that the average abundance of the fish population was between 0.43–1.34 individuals/m2 and in July 2017, the average abundance of the fish population was between 0.87–3.76 individuals/m2. The highest average fish product in the southwest monsoon season (July 2017) was about 3.46 Kilograms/Rai. The data of diversity, evenness and dominance indices of fish specimens showed that the fish specimens in the collecting sites that showed low to medium diversity (Hʹ; 0.73–1.73). The distribution of fish specimens in the northeast monsoon and the southwest monsoon seasons was not even, and some fish specimens were more dominant than the other specimens in each collecting sites.
