Whale shark landing A male whale shark, Rhiniodon lypus, 548cm totallengthofabout2.5 tonnes, was caught entangled in gillnet operated at a depth of 40m was landed on 30 July at Visakhapatnam. This was reported by Shri C.V. Seshagiri Rao, Shri K. Narayana Rao, Technical Staff, Visakhapatnam Research Centre. Good Catches of mackerel and sardine An encircling net, Edavabi operated in the early hours off Madras coast, brought good landings of mackerel, Rasfrelliger kanagurta (C/unit 450600 kg) during the first and third weeb of July. The catch rate of oil sardine, Sardinella longiceps in this net varied from 750-1300 kg/unit. Very interestingly, both the species wer$ never caught together in the net at a time. ; The mackerel Rasfrelliger kanagurta, the oil sardine, Sardinella longiceps and the mullet Mugil cephalus were obtained in large quantities in the encircling net Edavalai discontinuous!/ in August along the Madras coast. The catch perunitof mackerel varied from 310-600 kg, oil sardine, 600-1050kg and that of mullet, 310-650 kg. The high catches are attributed to migration of the fishes to coastal waters for feeding in the productive area. Resources assessment of Seaweeds at Minlcoy The agarophyte, Gracilaria edulis established itself in the natural beds in Minicoy lagoon has yielded a density range of 960g -1640 g/m2. The cast ashore seaweed of G.edulis along stretch of 228 m of shore amounted to 4500 g/day. The individual plant with a length upto 38cm is indicative of a very robust and healthy colonisation of G.edulis. Observations on the effect of repeated harvesting of G.edulis have shown an increase in average length of l /cm/30 days time.
