AQUATICS |
|
The term aquatic refers to water and can be either a noun or an adjective. Dictionary definitions do not specify what kind of water, although in both general use and in the sciences, the implication is that of fresh water. The term marine is typically substituted where reference to salt water is intended.

FISHERIES |
|
A fishery (plural: fisheries) is an organized effort by humans to catch fish or other aquatic species, an activity known as fishing. Generally, a fishery exists for the purpose of providing human food, although other aims are possible (such as sport or recreational fishing), or obtaining ornamental fish or fish products such as fish oil. Industrial fisheries are fisheries where the catch is not intended for direct human consumption (Castro and Huber 2003).
Regardless of purpose, however, the term fishery generally refers to a fishing effort centered on either a particular ecoregion or a particular species or type of fish or aquatic animal, and usually fisheries are differentiated by both criteria. Examples would be the salmon fishery of Alaska, the cod fishery off the Lofoten islands or the tuna fishery of the Eastern Pacific. Most fisheries are marine, rather than freshwater; most marine fisheries are based near the coast. This is not only because harvesting from relatively shallow waters is easier than in the open ocean, but also because fish are much more abundant near the coastal shelf, due to coastal upwelling and the abundance of nutrients available there.

A playground is an area designed for children to play freely. Modern playground often have recreational equipment such as the see-saw, merry-go-round, swingset, slide, climber, walking bridge, jungle gym, chin-up bars, sandbox, parallel bars, overhead ladder, trapeze and trapeze rings, playhouses, and maze, many of which help children develop physical coordination, strength, and flexibility, as well as providing recreation and enjoyment. Common in modern playgrounds are "play structures" that link many different pieces of equipment.
