A slot limit is a tool used by fisheries managers to regulate the size of fish that can legally be harvested from particular bodies of water. Usually set by state fish and game departments, the protected slot limit prohibits the harvest of fish where the lengths, measured from the snout to the end of the tail, fall within the protected interval.

Harvest – the number or weight of fish caught and retained from a given area over a given period of time. Note that landings, catch, and harvest are different. Note that landings, catch, and harvest are different.
Schaefer published a fishery equilibrium model based on the Verhulst model with an assumption of a bi-linear catch equation, often referred to as the Schaefer short-term catch equation: (,) = where the variables are; H, referring to catch (harvest) over a given period of time (e.g. a year); E, the fishing effort over the given period; X, the ...
The goal of fisheries management is to produce sustainable biological, environmental and socioeconomic benefits from renewable aquatic resources. Wild fisheries are classified as renewable when the organisms of interest (e.g., fish , shellfish , amphibians , reptiles and marine mammals ) produce an annual biological surplus that with judicious ...
Conditions improved over the next few years, including a large harvest of 1,251 sturgeon in 1972, but fell under bad luck again in 1973, when the eight-fish harvest tied with 1969's.

The two major fish species were the orange roughy (Hoplostethus atlanticus) and pelagic armourhead (Pseudopentaceros wheeleri), which were quickly overexploited due to lack of knowledge of the longevity of the fish, late maturity, low fecundity, small geographic range and recruitment to the fishery. As well as the fishes being overexploited the ...
Over the years, fish farming has made a name for itself in the fishing industry as a means of ensuring that the world's fish supplies do not deplete so rapidly. Sometimes referred to as "aquaculture", fish farming, when done right, can be one a very environmentally-friendly way to harvest fish. Fish farms are regulated by laws and management ...
