The life capacity of copepod's eggs passed through the gut of Ladoga lake Coregonus [Translation from: Zool.Journal.Moscow 29-5, 476-477, 1950]

This short paper summarises findings of experiments that were carried out using copepod eggs taken from guts of Coregonus which breeds in various Ural lakes. The study showed that copepod eggs can pass through the gut of Coregonus unharmed.

Fish production, catches and the carrying capacity of the world oceans

A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH II approach implemented as a new, Windows-based software is then shown to allow construction of a stratified world model accoutinng for global catches, production of and predation on fishes, and thus improved estimates of global potentials. A newly initiated, cooperative project is described through which the foundation for such a global model could be constructed, based on a stratified database with more than 100 trophic models. Collaborators are invited to join in this, and will be assisted in constructing models covering their areas of interest.

Survey on the idle capacity of fish processing (freezing) plants in India - 1. West Coast

The extent of idle capacity in fish processing (freezing) plants estimated by stratified random sampling is reported. The estimates for 1978 and 1979 for the processing plants on the west coast of India were 76.9 % and 73.2 % respectively at the rate of 250 working days per annum and two shifts per day. The percentage error of estimates worked out to 6.04 for 1978 and 6.98 for 1979. Substantial under utilization of processing plants noticed in all the states accounts mainly to the non-availability of raw material (prawn), high cost of production and shortage of power.

Survey on the idle capacity of fish processing (freezing) plants in India - 2. East coast

The extent of idle capacity in the fish processing (freezing) plants in the east coast of India estimated by stratified random sampling and the factors responsible for the same are reported. The estimates of idle capacity of fish processing plants in the east coast for the years 1978 and 1979 were respectively 75.9% and 72.5% on the basis of 250 working days per annum and double shift per day. The percentage errors of estimates worked out to 6.9 for 1978 and 4.7 for 1979. The corresponding figures were worked out on the basis of 200 working days also. Substantial under-utilisation of plants in all the maritime states in the east coast accounted mainly to non-availability of raw material, high cost of production, shortage of power, scarcity of ice and potable water during peak season and frequent labour troubles.

Enhancing capacity of fishing communities for resource management

International Collective in Support of Fishworkers (ICSF) undertook capacity development in six locations in five countries (India, Indonesia, Myanmar, Bangladesh and Thailand). Six workshops were undertaken to help communities develop proposals for the conservation and sustainable uses of fisheries resources.

Report of the BOBLME fishing capacity workshop, Phuket, Thailand, 12-13 January, 2015

The workshop focused on capacity utilisation estimation using Data Envelopment Analysis (DEA) to assess the fishing capacity of fleets.
