A 'Marine Fish Calendar' for Minicoy is presented here based on the .data collected during April, 1984 to March, 1987. Pole and line and surface trolling gears were responsible for about 95.85% and 4.14% respectively of the total fish landed; catch by hooks and line was negligible (0.01 %)

MINICOY* P. P. PiUiti. G. Gopukumur und K. K. KuaUkoyii MMcoy Research Centre of CMFRI. Minkoy Introductioa Despite the fact that tuna fishery at Minicoy (Long. 73" 00' E, Lat. 8'17'N) has been reported cailicr. the seasonality of total marine fish production and ti end of dlort is little known. In view of this a 'Murine Fish Calendar' for Minicoy is presented here based on the .' ita collected during April, 1984 to March, 1987. Pole and line and surface trolling gears were res-ponsible for about 95.85% and 4.14% respectively of the total fish landed; catch by hooks and line was negligible (0.01 %). Trend of effort indicate that pole und hue operations ore more prevalent during post and prcmunsoon seasons, whereas maximum efi'ort by troll line recorded was during monsoon months. Productive period for pole and line fishery is during Octobcr-Muy and for surface trolling June to September with a secondary maximum in February. Pooled average C/£ by pole and line fishery also indicate the same trend of that of the effort with primary peak during November-December and secondary one * Consuliduled by N. Copiiuiha Mcnon and K. Bulachandran, CMFRI, Cocliia. during March-April peiiod. C^tch per effort trend for troll line fishery was more oi less uoifoim throughout the period eventhough maximum effort expended was during the monsoon months. High catch rale recorded during February was the reflection of tiie effort put in during February, 1986. 2 0 * 18* 10* \ - > ^ INDIA LAKSHAOWECPN (^ ISLANDS \ \ 4i \ ) *M)NlCO\f\-/ 1 1 1 7 0 * 7 6 * 8 0 * as* i f 1 «o« In the pole and line fishery, skipjack tuna (KuisU' wonus pe/amisj contributed, on an average, about 90% of the total marine fish catch. Yellowfin tuna (Thwmus ulhacarcs) represented by sub-adults (young) occuiTcd 12 mainly during the postmonsoon period. Other com-ponents of the catch included rainbow runner (Elaga-tis bipinnulatus), little tuna (Euthynnus affinis), dolphin fish (Coryphaena hippurus) and small pelagic sharks in their order of abundance.

Stiusonal abundance of pole and line and troll line fishery ai Minicoy. Species diversity was high in the troll line catches; average annual pattern of occurrence of diiferent species in their order of abundance was: yellowfin tuna (sub-adults 38.7%), skipjack tuna (23.5%), Acanthocy-biuin iukiiu/ri (wahoo) (10.4%), pelagic sharks (7.3 %), htiophorus pUttypterus (sail fish) (5.4%), Caranx sp. (3.9%), Elagalis hipinnulatui (2.3%), Sphyraena sp. (1.8%), Euiliyiinus affinis and Auxis iluizunl (0.4%), Gyiunomnhi unUolor (0.4%), Coryphaeim hippurus (0.4%) and others (5.5%). A noticeable feature in the troll line lisiicry was the abundant occurrence of wahoo during postmonsoon months and young ycUowJin tuna during premonsoon months. Factois such as sea surface temperature, surface currents, wind pattern, availability and abundance of live-baits, tuna behaviour in the fishing ground and pre-sence of floatsam objects exert considerable influence on the fluctuation in the availability of tunas which is the mainstay of marine fishery at Minicoy. to* 60* 4 0 * 20* A M J J Y A b O N D J F M ^SAILFISH QOTHFRS Fig. 2.
