It has been called "the central problem of fish population dynamics" [14] and “the major problem in fisheries science". [15] Fish produce huge volumes of larvae, but the volumes are very variable and mortality is high. This makes good predictions difficult. [16] According to Daniel Pauly, [15] [17] the definitive study was made in 1999 by ...

An example of using age class structure to learn about a population is a regular bell curve for the population of 1-5 year-old fish with a very low population for the 3-year-olds. An age class structure with gaps in population size like the one described earlier implies a bad spawning year 3 years ago in that species. [ 7 ]

It covers 11.4 million square kilometres (4.38 million sq mi), which is the second largest zone in the world, exceeding the land area of the United States. [5] According to the FAO, in 2005, the United States harvested 4,888,621 tonnes of fish from wild fisheries, and another 471,958 tonnes from aquaculture. This made the United States the ...
NOAA Fisheries regulates commercial and recreational marine fishing in the United States under the Magnuson-Stevens Fishery Conservation and Management Act (MSA). [17] [18] Established in 1976, the MSA is the primary law governing marine fisheries conservation and management in U.S. federal waters.
