    Length Weight relationship of two Palaemonid Prawns,Macrobrachium idella and M. scabriculum- A comparative study
    (Society of Fisheries Technologists (India) Cochin, 1988) JAYACHANDRAN, K. V; JOSEPH, N. I
    Length-weight relationships of two commercially important freshwater prawns, Macrobrachium idella and M. scabriculum, have been worked out separately for the two sexes of the two species. 't' test showed that growth departs significantly from the isometric growth in the case of both sexes of M. idella and in the female of M. scarbriculum. Therefs re, the cubic formula W = CL 3 may be applied only in the case of males of M. scabriculum. In all the other cases W = CLD may be followed.

    TWO NEW RECORDS OF PALAEMONID PRAWNS FROM INDIAN WATERS
    (Society of Fisheries Technologists (India) Cochin, 1988) JAYACHANDRAN, K. V; JOSEPH, N. I
    descriptions with suitable illustrations of two species of palaemonid prawns — Macrobrachiu;n aernuluin and Palaemon (Palaemon) concinnus are furnished. M. aemulum has been enjoying an isolated distribution in New Caledonia. It is reported for the first time from India and is therefore a clear case of discontinuous distribution. Studies revealed that M. aemulum is distinct from M. nob ilii and the reasons for separating the two species are discussed. New distributional records for P. (P.) concinnus in the south-west coast of India are also given.
