Acoustic resource surveys were conducted by M/V SEAFDEC in the Gulf of Thailand and off the east coast of Peninsular Malaysia from September 5 to 28, 1995 for pre-NE monsoon season and from April 24 to May 17, 1996 for post-NE monsoon season, using the scientific echosounder FQ-70 (Furuno Electric Co.). Raw values of backscattering strength (SV) from the 200 ㎑ were carefully corrected and filtered to eliminate the influence of plankton. These corrected SV values were sorted out into pelagic and demersal fish, and were used to estimate biomass for each category of multi-species fish. Biomass of pelagic and demersal fish for each season was estimated both in the Gulf of Thailand within Thai EEZ and in the east coast of Peninsular Malaysia within Malaysian EEZ waters due to the availability of previous fisheries statistics and biological data. Dominant species were selected based on the fisheries statistics and landing place survey. Length (L) and weight were obtained from previous literature. Target strength (TS) of these dominant species were calculated as TS = 20 log (L) - 66. The distribution of the SV values for pelagic fish showed a distinct difference between pre and post monsoon seasons. Greater concentrations of SVs were observed from offshore compared to the nearshore waters in pre monsoon season. The distribution for the demersal fish showed that there was no clear difference between pre and post monsoon. The estimated biomass of multispecies fish in the Gulf of Thailand within Thai EEZ for the pre and post monsoon seasons was 9.2 × 10^5 tonnes (5.5 × 10^5 tonnes of pelagic fish and 3.7 × 10^5 tonnes of demersai fish) and 4.7 × 10^5 tonnes (2.0 × 10^5 tonnes of pelagic fish and 2.7 × 10^5 tonnes of demersal fish), respectively. The estimated biomass of multi-species fish off the east coast of Peninsular Malaysia within Malaysian EEZ for the pre and post monsoon seasons was 4.4 × 10^5 tonnes (2.3 × 10^5 tonnes of pelagic fish and 2.1 × 10^5 tonnes of demersal fish) and 3.1 × 10%5 tonnes (1.9 × 10^5 tonnes of pelagic fish and 1.2 × 10^5 tonnes of demersal fish), respectively.

A preparatory study on fish behavioral properties in a set-net
KANG, Myounghee,LIU, Jenming,HASSAN, Raja Bidin bin Raja,FAJARYANTI, Rina,HWANG, Bokyu The Korean Society of Fisheries and Ocean Technolo 2020 수산해양기술연구 Vol.56 No.2
The fish influx and behavioral properties at a set-net off Goseong, South Korea were investigated using an imaging sonar. As a result, the average influx of fish was 33.9% at day time and 66.1% at night time, respectively, which indicated that a majority of fish entered into a playground in the set-net at night. The fish behavioral properties such as target (fish) length, range, orientation and major-axis angle were examined and compared among survey dates (4, 5, and 6 June 2019) using the statistical analysis tool (analysis of variance, ANOVA). The behavioral properties presented differently sometime of survey dates. This is preparatory study to support fish behavior properties in a set-net. It is expected that more elaborated behavioral information of fishes in the set-net is beneficial for designing and deploying a set-net fishing gear as well as general fish behavior research in the future.
