Slot Limit
A slot limit is a tool used by Fishery, 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 fish measurement, lengths, measured from the snout to the end of the tail, fall within the protected interval. For example, on a body of water where there is a protected slot limit on largemouth bass between , largemouth between those lengths may not be harvested. In this example largemouth bass shorter than and longer than may be removed from the water and kept for personal use in accordance with local fishing regulations. Slot limits are based on the principle that bass populations exhibit different habitat requirements during different phases of their lives. Slot limits focus on protecting one segment of the life history which can influence overall fishing success. A minimum landing size is a similar regulation in comm ...

Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Lake Mille Lacs
Mille Lacs Lake (also called Lake Mille Lacs or Mille Lacs) is a large but shallow lake in the U.S. state of Minnesota. It is located in the counties of Mille Lacs, Aitkin, and Crow Wing, roughly 75 miles north of the Minneapolis-St. Paul metropolitan area. ''Mille Lacs'' means "thousand lakes" in French. In the Ojibwe language of the people who historically occupied this area, the lake is called ''Misi-zaaga'igan'' ("grand lake"). Physical features Mille Lacs is Minnesota's second-largest inland lake at , after Red Lake. The maximum depth is . Much of the main lake has depths ranging from 20- to 38-feet. Gravel and rock bars are common in the southern half of the lake. Islands Mille Lacs Lake hosts numerous islands, many of which are an acre or smaller and are in private ownership. The following list is in order from largest to smallest. * Malone Island (35 acres) * Mulybys Island (5.35 acres) * Upper Twin Island (3.75 acres) * Rainbow Island (3.25 acres) * West Lowe ...

Bag Limits
A bag limit is a law imposed on hunters and fishermen restricting the number of animals within a specific species or group of species they may kill and keep. Size limits and hunting seasons sometimes accompany bag limits which place restrictions on the size of those animals and the time of year during which hunters may legally kill them. Those who violate these laws or other hunting laws are known as poachers. In most cases, bag limits serve to keep a healthy population for the carrying capacity of the species' environment. This is done by utilizing hunters and fishermen, to harvest only a selected number of the mature game species. These bag limits are utilized by a multitude of Countries and Fish and Game enforcement agencies. Although like all law and regulation enforcement agencies, poorer regions of the world have limited ability to enforce these regulations. Examples Florida bass fishing In southern Florida, licensed fishermen may keep no more than five largemouth bass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minimum Landing Size
The minimum landing size (MLS) is the smallest fish measurement at which it is legal to keep or sell a fish. The MLS depends on the species of fish. Sizes also vary around the world, as they are legal definitions which are defined by the local regulatory authority. Commercial trawl and seine fisheries can control the size of their catch by adjusting the mesh size of their nets. Effect of selection on fish sizes The idea behind this limitation is that only the older, mature fish get taken, leaving juveniles behind to continue breeding and propagating their species. There is some criticism of this legal requirement, however, as it applies selection pressure to the fish: as the larger fish get taken, the genes for larger size are reduced or removed from the gene pool, while fish that mature at a smaller size continue breeding. The average size of fish shrinks over time. This has led to a collapse in the amount of fish being caught in some fisheries. Aboriginal Australians around Mo ...

Lake Fork Reservoir
Lake Fork Reservoir is a reservoir located in Wood, Rains, and Hopkins counties in the state of Texas, between the towns of Quitman, Alba, Emory, and Yantis, Texas. It was impounded by the Lake Fork Dam in 1980, and reached its normal pool surface elevation of above mean sea level in 1985. It consists of , offers of shoreline, and has a drainage area of . The dam is in length and impounds Lake Fork Creek, a tributary of the Sabine River, and other major creeks are Big Caney and Little Caney. The dam and reservoir with a maximum capacity of are owned and operated by the Sabine River Authority, a state agency. It officially serves as a reservoir for Dallas and its suburbs. However, it is best known for its fishing, as it holds 15 of the top 20 Texas State Record largemouth bass ever caught, making it one of the premier trophy bass fishing lakes in the world. Fishing Lake Fork Reservoir was created as a textbook fishery, including initial stockings before the lake fille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortality Rate
Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or incidence of a disease, and also from the incidence rate (the number of newly appearing cases of the disease per unit of time). An important specific mortality rate measure is the crude death rate, which looks at mortality from all causes in a given time interval for a given population. , for instance, the CIA estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population per year. In a generic form, mortality rates can be seen as calculated using (d/ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recruitment (biology)
When discussing population dynamics, behavioral ecology, and cell biology, recruitment is several different biological processes. In population dynamics, recruitment is the process by which new individuals are added to a population, whether by birth and maturation or by immigration. When discussing behavioral ecology and animal communication, recruitment is communication that is intended to add members of a group to specific tasks. Finally, when discussing cell biology, recruitment is the process by which cells are selected for certain tasks. Recruitment in population dynamics Definition and importance In population dynamics and community ecology, recruitment is the process by which individuals are added to a population. Successful recruitment is contingent on an individual surviving and integrating within the population; in some studies, individuals are only considered to have been recruited into a population once they've reached a certain size or life stage. Recruitment can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Largemouth Bass Slot Limit Diagram
The largemouth bass (''Micropterus salmoides'') is a carnivorous freshwater gamefish in the Centrarchidae ( sunfish) family, a species of black bass native to the eastern and central United States, southeastern Canada and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth.

Spawning
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small ...

Walleye
The walleye (''Sander vitreus'', synonym ''Stizostedion vitreum''), also called the yellow pike or yellow pickerel, is a freshwater perciform fish native to most of Canada and to the Northern United States. It is a North American close relative of the European zander, also known as the pikeperch. The walleye is sometimes called the yellow walleye to distinguish it from the blue walleye, which is a color morph that was once found in the southern Ontario and Quebec regions, but is now presumed extinct. However, recent genetic analysis of a preserved (frozen) 'blue walleye' sample suggests that the blue and yellow walleye were simply phenotypes within the same species and do not merit separate taxonomic classification. In parts of its range in English-speaking Canada, the walleye is known as a pickerel, though the fish is not related to the true pickerels, which are members of the family ''Esocidae''. Walleyes show a fair amount of variation across watersheds. In general, fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
