A significant factor contributing to the depletion of the cod stocks off Newfoundland's shores was the introduction of equipment and technology that increased landed fish volume. [5] From the 1950s onwards, new technology allowed fishers to trawl a larger area, fish more in-depth, and for a longer time, with the catches peaking in the 1970s and ...
Fisheries managers use stock assessments to help determine if a stock is overfished, measuring the maximum sustainable yield. [25] If a stock is designated as overfished, annual catch limits need to be low enough to allow stocks to rebuild. [23] Worldwide, about one-third of fish stocks are being fished at biologically unsustainable levels. [26]
Catches and landings must be recorded. Regulations cover the kind of fishing gear that may be used. Areas may be closed from fishing to allow stocks to recover. A minimum size for catch led to fishermen dumping dead fish that were too small to land legally, so a minimum mesh size was introduced, which let small fish escape to replenish stocks ...
Fish stocks are subpopulations of a particular species of fish, for which intrinsic parameters (growth, recruitment, mortality and fishing mortality) are traditionally regarded as the significant factors determining the stock's population dynamics, while extrinsic factors (immigration and emigration) are traditionally ignored. Stocks fished ...
Declining fishing stocks and frequent tax evasion led the Hansa cabal to close the fisheries near Bergen off the Norwegian coast in 1410. English fishermen responded by taking their craft to the closed Icelandic colony and trading and fishing there in 1412. Besides several local fishing boats, very few if any ships had visited Iceland in ...

Commercial fishermen off the coast of Alaska have found what officials are concerned could be another spy balloon and are bringing it to shore with them, three sources familiar with the matter ...
Today, due to the pre-allocation of catch that accompanies IFQs, the season lasts nearly eight months and boats deliver fresh fish at a steadier pace. However, halibut stocks have been in continuous decline for over a decade, as poor stock assessments leading to overfishing have caused a substantial decline in biomass. Additionally, despite the ...
