    Growth, Survival Rate and Feed Conversion Ratio of Juveniles of Macrobrachium rosenbergii (de Man) Fed with Farm made and Commercial Feeds
    (Society of Fisheries Technologists (India)Cochin, 2003) B., Hari.; Kurup, B. Madhusoodana
    Feeding trial was conducted in M. rosenbergii to compare efficiency of the farm made feed (diet FMF) with commercial feeds like CP feed (diet A), Higashi feed (diet B), and Rosen feed (diet C). Dried clam meat was used as the control feed (diet D). Water stability of FMF is found well comparable with the above feeds. Higher specific growth rate was recorded in diet FMF (2.02) that did not vary significantly (p>0.05) among the dietary treatments except in diet D (1.15). Higher survival was recorded in diet FMF (91.07%) followed by diet A (90.48%), diet B (89.68%) and diet C (82.14%) while the survival of the juvenile of M. rosenbergii fed with control diet (37.5%) was significantly (p<0.05) lower compared to other treatments. Feed conversion ratio recorded for diet FMF was comparable with that of diets A and B. Protein efficiency ratio was significantly higher (p<0.05) in diet B (0.86), A (0.78) and FMF (0.77) when compared to diet D (0.31). Cost of diet A and B (200%), C (185%) and control diet (169%) was significantly higher than diet FMF. Results of the present study revealed that the growth, survival and feed conversion ratio of M. rosenbergii fed with farm made feed prepared from the locally available feed ingredients were comparable with those of commercial scampi feeds. As the farm made feed preparation was found very cost effective it can be recommended to the scampi farmers of Kerala to make farming more economically viable and feasible

    Performance of Inboard Diesel Engine Fitted Canoes Operating Ring Seine along Kerala Coast
    (Society of Fisheries Technologists (India)Cochin, 2003) Kurup, B. Madhusoodana; Rajasree, Radhika
    The performance of the recently introduced Inboard Engine(IBE) fitted crafts operating ring seine is reported. 153 units were enumerated from 8 districts of Kerala. The total landing from IBE canoes was found to be 11745 tonnes, with an average catch per unit effort of 1826 kg and average catch per hour 555 kg. The operation cost and revenue generated from ring seine operated by Out Board Motor canoes and IBE canoes are compared.
