A fishery officer is responsible for the consecration and protection of fisheries. He carries out surveys of aquatic life, investigates fish mortalities and studies ater quality. All these people play an important role in aquaculture and together they create food for millions of
Therefore, it has high ecological value. There are two sea-grass species, which are Oval Halophila and Dwarf Eel Grass, could be found in Lai Chi Wo. The Dwarf Eel Grass has roots, leaves and stems. It takes root in floating mud and extracts the soil nutrients through the roots.

In the United States in particular, 40 percent of our wetlands are coastal wetlands and just over 80 percent of those coastal wetlands are found in the Southeast (NOAA). Coastal wetlands can take on several different forms, including the salt marshes that line our bays, freshwater marshes, mangrove swamps, hardwood swamps, and seagrass beds (NOAA). Humans are connected to coastal wetlands in more ways than they may or may not know. Coastal wetlands are greatly responsible for the various seafood we indulge in every year. These wetlands provide the perfect habitat for the reproduction and feeding of many wildlife, including lobster, shrimp, crabs, oysters, and many types of fish including salmon and bass (NOAA).
Every year the Salton Sea International Bird Festival attracts thousands of bird lovers from around the world. Gentile da Fabriano, “Adoration of the Magi” Palla di Noferi Strozzi commissioned this famous altarpiece, signed and dated 1423 on the frame, for his family's chapel in the church of Santa Trinita in Florence. Wealth and culture of the donor are reflected in the lavish use of gold and in the pomp of the Magi procession, including also exotic animals as leopards and monkeys. If in this picture clearly emerges the persistence of International Gothic at the beginning of 15th Century, in the meanwhile the panel is ahead of its time showing in the propeller’s scenes (Nativity, Rest during the Flight into Egypt and Presentation to the Temple) one of the basic innovations of Renaissance art: the blue sky at the place of the traditional gold background
That’s why they are called rain forest, because they receive a lot of rain fall each year. Why do people need to protect our rain forest? Rain forest should be protected because they provide an enormous benefit to human kind. It is home to fifty-million Indigenous people. Also is a habitat for over a thousand species of plants and animals and birds.
Next, I got to meet some of the education birds. The World Bird Sanctuary provides birds of prey for wildlife education programs all over the United States. Ravens take a dollar bill and put it in the collection box during the World Bird Sanctuary’s “Birds in Concert,” which are every Thursday in August. During Birds in Concert trained birds of prey fly over the audience. World Bird Sanctuary has many other educational programs run by staff, interns and volunteers, both on and off site.
(http://www.nmfs.noaa.gov/aquaculture/what_is_aquaculture.html, 2017) There are many ways to farm marine shellfish, including “seeding” small shellfish on the seafloor or by growing them in sinking or floating cages. Marine fish farming is typically done in net pens in the water or in tanks on land. U.S. freshwater aquaculture produces species such as catfish and trout. Marine aquaculture refers to the culturing of species that live in the ocean. Marine aquaculture produces mostly oysters, clams, mussels, shrimp, and salmon as well as lesser amounts of cod, moi, yellowtail, barramundi, seabass, and seabream.

Aquaculture also supports a variety of year-round jobs. The American aquaculture industry is worth roughly 1.2 billion dollars. The Chinese produce an overwhelming 62% of the world seafood supply from aquaculture. Environmental concerns have slowed down production particularly in the United States.
Aquaculture Aquaculture is a form of agriculture that involves the propagation, cultivation and marketing of aquatic organisms in an controlled environment. The history of aquaculture first begun in ancient China some 4000 years ago with ornamental carp ponds to today's $264 million commercial production of catfish in the southern states of America. 1 The following essay will be a broad examination of the conditions and requirements of aquaculture and a closer study of the industry in Western Australia. It should be noted that the industry is only at a fledgling stage with a handful of organisms in commercial production. However, there is one segment that is a major success with $153 million worth of merchandise a year.
One of the bays biggest resources is oysters. Oysters are filter feeders which mean they pump water through their gills trapping algae, sediments and nutrients as they release clean the water back into the bay. The material collected through the oysters digestive process forms crystallized layers of nutrient rich matter which sometimes develop into pearls. Filtering the water provides food for the the oysters to grow and also helps to continuously clean the Chesapeake Bay. One oyster can filter fifty gallons of water within a twenty-four hour period according to many sources.
