Abstract

• This study is a piece of research work carried out as a sample to analyze the level of marine aquatic fauna exploitation and which species stocks needed to be sustained. The present study was an evidence based study obtained from 47 marine fauna of the daily catch weights and its respective daily prices of each species stock of Nyaung Tan Fish Jetty, Pazundaung Township, Yangon Region. The relationship between yearly average catch weights and yearly average prices were analyzed by Pearson's Correlation Coefficient method. It was observed that there were significant negative correlation between yearly average catch weights and yearly average prices as R2= 0.7628, r= - 0.8860 for 2018 and R2= 0.6634, r= - 0.8144 for 2019. To find out the level of exploitation of aquatic species, four groups were classified according to FAO, 2017 as (i) Lesser than 1000 kg, (Over exploited), (ii) 1000 kg - 10000 kg, (Fully exploited), (iii) 10000 kg - 100000 kg (Moderately exploited) and (iv) Above 100000 kg (Under exploited). Among them, levels of exploitation was found to be the highest from (Lesser than 1000 kg), which was regarded as over exploited group. It included 28.7% of aquatic species out from the average records of 2018 and 2019. Therefore, for the 28.7% of the aquatic species that were found to be over exploited, which were high in fishing pressure. The fishery potential has been exceeded and these stocks are in the unsustainable conditions. This will become bad for every thing if the nutritional value and commercially demanded aquatic species are lost in the ecosystem. In order to conserve these aquatic stocks, preventive managements are needed to monitor the decling aquatic species in the catch to control the fishing gears and to exclude the spawners from catching during the breeding seasons of the marine aquatic fauna.
