Influence of photoperiod and rainfall on body length of male and female freshwater prawn "Macrobrachium rosenbergii"


Author(s): N Anitha and G Sirisha

Abstract: The speculation that climate change may impact on sustainable prawn growth suggests a need to understand how these effects influence body length of prawn. It is well known that growth in crustaceans is influenced by abiotic factors like photoperiod and rainfall. These factors were studied on the body length of freshwater prawn Macrobrachium rosenbergii under natural environmental conditions from June to March. The results revealed that the minimum and maximum photoperiod is found to be 4.3 h to 8.5 h respectively. The rainfall highly recorded is 545.8 mm in November. The body growth of prawn is dependent only in monsoon and post monsoon periods. However, the present study deals with the study of influence of abiotic factors such as photoperiod and rainfall on increase in body length in male and female prawns that can be implemented in aquaculture practices for the better yield of production.
