What are the reasons for the collapse of the west coast fishery?

The collapse of the east coast fishery had several causes.

1. Pollution. Pouring untreated sewage into the east coast waters killed a large number of fish.

2. Habitat loss. Many of the fish use the wetlands and streams as places to lay their eggs and as nurseries for their young. When the meadowlands are filled in they are no longer the nurseries for little fish. Little fish can no longer leave home to grow up to become big fish. Simply because no one saw the tons of little fish produced by the meadowlands every day did not mean they would not miss the tons of big fish they would become as they were eaten and as a few grew into those big fish.

When streams are dammed, Atlantic Salmon and other fishes can not swim upriver to lay their eggs. (Enough were already killed trying to swim upstream in polluted rivers.)

3. Over fishing. When entirely too many big fish are caught, not enough little fish will be produced to replace them. It still takes one large male and one large female fish to produce fertilized eggs. Enough of those must grow up for the fishery to recover. Right now that is difficult.

How do laws that limit the sizes of fish help protect fishery resources?

Laws that limit the sizes of fish help protect fishery resources by ensuring that fish have the opportunity to reach maturity and reproduce before being harvested. By establishing minimum size limits, these regulations prevent the overfishing of juvenile fish, which can lead to population declines. Additionally, size limits can help maintain a balanced ecosystem by allowing larger, more reproductive individuals to contribute to the population's genetic diversity and resilience. Overall, these measures promote sustainable fishing practices and the long-term health of fish stocks.

Why are many successful fisheries located near areas of upwelling?

Improve

because they have high nutrient levels. These nutrients are used by alage, which is then eaten by zooplankton. The zooplankton become Why_are_upwelling_zones_usually_home_to_schools_of_fishfor the fish, and so there is a large food source in these areas. This plentiful food source can then support huge schools of fish. And stuff like that.

What is fecundity in fishery?

In terms of reproduction, fecundity means the biological ability to have a particular quantity offspring. Fertility means the actual use of fecundity to produce the offspring. Both terms can be used either of an individual or a population.

In everyday speech, most people use the term "fertility" to cover both meanings. But when needing to distinguish the ability to have offspring from the actual use of the ability, "fertility" should be used for reproductive ability, and "fecundity" for actual number or rate of offspring.

What are the three Atlantic continental shelf areas that are famous fisheries?

The three Atlantic continental shelf areas that are famous fisheries are the Grand Banks, the area east of Nova Scotia, and Georges Bank. The Grand Banks are east of Newfoundland, Canada's easternmost province. The second area is found east of Nova Scotia in the area that adjoins Sable Island. Georges Bank is south of Nova Scotia. The continental shelf is relatively shallow so that plants and nutrients are available to fish. As a result, these fishing grounds supplied many fish, including tuna, halibut, mackerel, cod, and swordfish, for hundreds of years. In recent decades, however, fishing stocks have declined. Over-fishing has resulted in insufficient fish being available to replace the fish taken.
