Transportation of fish - 1. A preliminary study on insulated containers and their efficacy in long distance transportation

Polythene lined thermocole insulated plywood boxes (second-hand tea chests) could be successfully used for transport of fresh iced fish. It was found that a minimum of 25 mm thermocole insulation was necessary during summer (April to June) and 15 mm during winter (Nov. to March). By using these insulated boxes the initial fish to ice ratio could be brought down to 1:0.75 and still further to 1:0.5 at the height of winter in Jan. and Feb. These second-hand tea chests are robust and are able to stand a minimum of 5 trips to and fro. The moulded polystyrene boxes are not suited for long distance transport. Another redeeming feature in the entire operation was that there was practically no loss of fish due to spoilage in transit. 100% of the fish transported was in acceptable condition and could be marketed. In the non-insulated boxes used by the trade, the loss due to spoilage ranged from 10% to 25%, and this could be completely eliminated by the use of these insulated boxes.

Studies on long wing trawl for shrimps off Kakinada (A.P.) coast - (i) Results of comparative fishing experiments with the conventional two seam trawl

Comparative fishing operations with the conventional two seams net and a 29.26 m. long wing shrimp trawl of four seam type were undertaken. The result showed that the four seams net gave nearly twice prawn catch than that of the conventional type. It was also found that the four seams net can be developed into a combination trawl for the effective exploitation of both prawns and fish along the coasts off Kakinada.

Investigations on long distance transportation of fish 1. Transportation of frozen fish from Cochin to Calcutta

Oil Sardine (Sardinella longiceps), mackerel (Rastrelliger kanagurta), cat fish (Arius sp.), threadfin bream (Nemipterus japonicus) and ribbon fish (Trichurus sp.) were frozen in glazed/unglazed blocks, packed in expanded polystyrene (EPS) insulated plywood boxes with and without additional ice and despatched in uninsulated parcel vans of trains from Cochin to Calcutta. The consignments reached the destination in excellent condition and were readily disposed off.

Change in quality of different variety of fish during long distance transportation

A study was conducted to investigate the quality of iced fish of different species during long distance transportation. Total bacterial counts showed different species to show different quality deterioration under similar handling conditions.

Shark long line gear of India

Sharks are mainly harvested with long lines which is less expensive compared to other methods of fishing. Though this is a common gear operated along the coast, the gear in every region has its own peculiarities in construction and rigging. This communication furnishes detailed description of the gear operated in different centres. Suggestions are also offered to improve the gear and methods for enhancing production.

Socio-economic and marketing aspects of Laila and Bottom Long Line fisheries in the Kalpitiya peninsula of Sri Lanka

Surrounding Net Fishery (laila) and Bottom Long Line Fishery which operate in the coastal waters of Kalpitiya Peninsula, compete for the same fish resources, resulting in a fishery dispute between the respective fishermen. Both fisheries target demersal as well as mid pelagic fishes, such as travellys (parava), mullets (galmalu) and barracudas (ulava). As the dispute had an adverse impact on the social harmony in the fishing community of the area, a socio-economic survey was conducted to study the underlying factors and to suggest policy measures to resolve the issue. The laila fishermen were resident fishermen in the Kalpitiya Peninsula while bottom long line fishermen were migratory fishermen from Negombo and Chilaw areas in the west coast of Sri Lanka. The Kalpitiya peninsula is located in the North West coast, some 50 km away from the west coast. Although the educational level and literacy rate of the laila community was below that of the bottom long line community, the laila community was economically better off. The net economic returns from laila fishery were superior to that from bottom long line fishery. The boat owner's and crew's share per operation of laila fishery were Rs.3,736 and Rs.947 respectively. The same figures for bottom long line fishery were Rs.588 and Rs.327 respectively. The resource rent from laila fishery was Rs.5,860, however, and much higher than that for bottom long line fishery (Rs.275), showing that the laila fishery exploits the targeted fish resource at a much higher rate compared to bottom long line fishery. This situation badly affects the equitable distribution of resources between the two fishing communities and results in unequal economic gains. Based on the findings of this study, certain input/output controls are proposed to address this problem, among which is the need to increase license fee for laila fishery units to offset the higher exploitation rate of fish resources.

The long road to freedom: the end of apartheid has signalled a new beginning for women in South Africa’s fisheries but real equality is still a far-off dream

Women in fishing communities are increasingly moving from traditional, community based occupations to seeking employment in the labour market. While this is an opportunity for women, their employment is also largely in the male dominated fishing industry, where job segregation into ‘less skilled and low paid’ jobs for women define employment opportunities. However, engagement as members in local non-government networks help women to challenge these stereotypes. In South Africa, for instance, the recent legislation promoting opportunity for women in male dominated sectors of employment is an opportunity for women to earn wages equal to those of men.

Europe: new, but long overdue

Small-scale fishers in Europe have established a low-impact fishing platform to further fishing in a sustainable and socially and economically viable manner....
