Spawning Season of Giant Freshwater Prawn (Macrobrachium rosenbergii De Man, 1879) in Trang River
Abstract
This study aimed to study giant freshwater prawn (GFP, Macrobrachium rosenbergii de Man, 1879) spawning season in Trang River, Trang Province. GFP data were surveyed from 2 local collectors in Trang River area. Sex, size and number of berried female were recorded twice a month, while the ovary weight were sampling every 2 months. The data collecting period was 11 months from May 2020 to March 2021. Data analysis was using descriptive statistic. Chi-square was used to compare sex ratio and gravid female of female ratio. Oneway ANOVA and Scheffe test were used to test the variances and compare means of carapace length and GFP weight by month. The study results showed that GFP in Trang River was spawning throughout the year, especially in late rainy to cold season (October-February). The gravid female was 42.4% of total female. The peak was found in July 2020 to February 2021 (chi-square = 110.91, p<0.01) which in accordance with the gonadosomatic index. The indexes were highly statistically significant differences classified by months (p<0.01), and reached the highest peak in January 2021 and followed by the indexes in November and September 2020 (6.25±4.11, 6.19±4.60 and 5.81±3.52,) respectively.
