    Twenty seven commercial Macrobrachium species are found in Asia and the Pacific Ocean. Most of them are inhabited in freshwater except few are exclusively marine oriented. Few species live in brackish water especially in the mouths of rivers. A close examination of M. idea males reveals that three distinct morphotypes based upon size ranking, the ratio of claw length to body length (relative claw length) which included small male (SM), medium sized male (MS) and bigger sized male (BS). The mating behaviors of three different males 4 experiments were conducted by (1) 3 BS males (90-100 mm) vs. female (50-75 mm); (2) 3 MS males (60-75 mm) vs. female (50-75 mm); (3) 3 SM males (45-55 mm) vs. female (50-75 mm); (4) 1BS male, 2 MS males and 3 SM males vs. female (55-75 mm). The mating behaviour of M. idae was divided into four phases such as (I) Contact: When the male recognize the pre-mat.. Read More»
