Conversion coefficients for fish catch statistics are the results of 28 years of Norwegian–Russian cooperation in the field of fisheries

Fisheries
The establishment of uniform conversion coefficients for the production of products from aquatic biological resources is one of the important measures to regulate the fishing of a joint stock of aquatic biological resources within the framework of the Joint Russian-Norwegian Fisheries Commission (RNFC), since the reliability of the calculation of the ...

The reliability of fishing statistics as a source for catches and fish stocks in antiquity [PDF]

, 2005
In 1985, T.W. Gallant published an influential essay on the potential productivity of fishing in the ancient world. He concluded that: ”the role of fishing in the diet and economy would have been, on the whole, subordinate and supplementary…” His methodological approach was original in using modern fishery data to estimate the productivity of ancient ...

Ecological restoration amplifies riverine fish catch of Gudusia chapra (Hamilton, 1822): an impact study in the river Ganga using multivariate statistical tools and water quality indices

Environmental Monitoring and Assessment
Fish residing in the aquatic ecosystem are considered the best ecological indicator for monitoring environmental habitat. To evaluate the changes that occurred due to relative restoration in the ecological habitat, a study was conducted in the freshwater zone of the river Ganga between Buxar, Bihar, and Ballia, Uttar Pradesh, between July 2021 and July

The Value of Catch-Statistics-Based Management Techniques for Heavily Fished Pelagic Stocks with Special Reference to the Recent Decline of the Southwest African Pilchard Stock

1981
The relatively short life-span of pelagic species, coupled with substantial year-class size fluctuations, makes it unlikely that management on the basis of models hypothesising a steady-state situation will prove adequate. Harvesting in excess of very conservative levels of exploitation necessitates monitoring of the current biomass of the stock.

Statistical relationships between palagic fish catches and long-term series of environmental conditions in the southern Benguela region

1991
Three different techniques are used to established statistical relationships between annual pelagic fish species catches viz. pilchard, horse mackerel and chub mackerel, and monthly environmental indices. The three techniques are Spearman's Rank correlation, multiple regression and cross-correlations of the Box-Jenkins time series approach.
