The survey was conducted in Kholpatua river from January 2014 to December 2014 and was compared with the ten years old secondary data. The results showed that there was a 41.57% decrease in number of catches ofP. monodon PL. over the course of time from ten years ago to the year of 2014. Although the number of active fishermen＇s boats have increased from 250 to 360 in ten years. The study also showed that the severe shrimp seed collection activities reduced the availability ofP. monodon PL. at Satkhira district, which has a severe negative impact on the availability of total catches. To control such decrease of P. monodon PL. in Bangladesh, more intensive study should be done.展开更多
