    Intraspecific resource partitioning by Hampala macrolepidota(Van Hasselt) in lotic and lentic environment of Kenyir reservoir, Malaysia
    (Fakulti Perikanan dan Sains Samudera, 1995-12) Chowdhury, Ahmed Jalal Khan
    A study of Iniraspecific Resource Partitioning on a tropical sport fish 'Side bar barb' Hampala macrolepidota van Hasselt. was carried out in lotic and lentic habitat at Kenyir Reserv oir, Terengganu, Malaysia.Physico-chemical regimes of Kenyir Reservoir were also studied to determine the species ecological requirements. The water quality data showed that Kenyir Reservoir is suitable for fish culture. The most vital ecological factors, temperature and dissolved oxygen levels, were within the acceptable range for fish until 10.0 m depth. Waterlevel and rain fall both showed significant (P<05) effects on the availability offish in both habitats.

    Studies on nutrition and development of digestive function in tropical sport fish Tor Tambroides (Bleeker) fry
    (Fakulti Sains dan Teknologi, 2000-05) Chowdhury, Ahmed Jalal Khan
    Malaysian mahseer Tor tambroidesA locally known as "Kelah" is a well known sport fish in Malaysia and recent catch statistics indicated that this highly valued species have declined and can be considered as endangered. In order to facilitate restocking programme, a study on nutrition was conducted at UPM, Terengganu. E i A t experiments were carried out to determine the feeding frequency, stocking density, optimal protein level and additives, digestibihty, development of enzymes, carotenoids and replacement of live foods of T. tambroides fry (mean SL 6.0 mm-lO.O mm and weiAiing 0.06-0.08 g).
