Economics of troll line operation during monsoon in Minicoy, Lakshadweep

The Economics of troll line operation during monsoon is given based on the study carried out in 1999. The average initial investment of a troll line unit 5 m OAL with outboard engine of9.9.HP) was found to be Rs.91 , 000/-. The average share of a unit was 616 kg when the fuel was also supplied by the owner along with the craft, outboard engine and gear realising a revenue of RS.28 ,880/-. But the share was 462 kg when the fuel was not supplied realising a gross income ofRs. 21,660/-. The gross profit in the former case was Rs.17, 880/- whereas in the latter case, it was gross income itself indicating the better profitability of the lattersystem

Indigenous substitutes for "Lignum vitae" for making stern bearings for fishing boats

Difficulties are very often encountered in selecting proper material for making stern bearings for fishing boats. Conventional materials such as white metal, bronze etc. wear out too fast also causing considerable wear to the propeller shaft. Lignum-vitae, a natural wood commonly used for this purpose, is not available on a commercial scale in our country. Results of trials carried out to find out suitable substitutes for lignum-vitae from among indigenous timbers are presented in this paper

Stomach content analysis of the Indian mackerel Rastrelliger kanagurta (Cuvier) from Calicut, Kerala

The food and feeding of the Indian mackerel Rastrelliger kanagurta was studied from Calicut based on 1,551 fishes ranging in size from 100 to 280 mm total length (TL) collected from both multi-day trawlers and ring net during the period January to December 2006. There was a preponderance of empty stomachs in all the months. The dominant food item was copepod. Sand and foraminiferans also formed part of the stomach content. The fish, Bregmaceros sp. was noticed for the first time in the adult mackerel

Impact of ring net on the mackerel fishery at Calicut

With the introduction of ring net, there was considerable improvement in the mackerel fishery. The mackerel landing was almost fully contributed by ring net. During post-ring net period,16684 manpower brought 970 tonnes of mackerel with a catch per manpower of 58.14 kg. Due to the small mesh size of ring net and their better efficiency, the gear can cause over fishing and hence the fishery has to be watched closely in the coming years
