The minimum habitat requirements for captive lined seahorses consist of a tank 18 inches vertical in height and 20 to 25 gallons for a pair, 30 to 40 gallons for two pairs. The tank should be kept at a constant temperature between 22 and 25 degrees Celsius (72 and 77 degrees Fahrenheit). [ 8 ]
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.

Carrying capacity – the supportable population of a species, given the food, habitat conditions and other resources available within a fishery. Casting – the act of throwing bait or a lure over the water, using a fishing rod. Catadromous – fish that live their adult lives in fresh water lakes or rivers but migrate down rivers to spawn in ...
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
Productivity may be measured by density, survival, growth and movement to adult habitat (Beck et al. 2001). There are two general models for the location of juvenile habitats within the total range for a species which reflect life history strategies of the species. These are the Classic Concept: Juveniles and Adults in separate habitats.
