Aquaculture is the farming of aquatic organisms such as fish, crustaceans, mollusks, aquatic plants. It involves gathering freshwater and saltwater populations under controlled settings, and can be compared with commercial fishing, which is the harvesting of wild fish. Farming implies some form of involvement in the nurturing process to enhance production, such as regular stocking, feeding, and protection from predators. It also implies individual or business ownership of the stock being gathered. The reported output from global aquaculture operations would supply one half of the fish and shellfish that is directly consumed by humans.
Such operations limit habitat damage, disease, escapes of farmed fish and the use of wild fish as feed. (https://www.seafoodwatch.org/ocean-issues/aquaculture, 2017) Freshwater aquaculture produces species that are native to rivers, lakes, and streams. U.S. freshwater aquaculture is dominated by catfish but also produces trout, tilapia, and bass. (http://www.nmfs.noaa.gov/aquaculture/what_is_aquaculture.html,
Fish have been found throughout many different cultures as food for many. Today it has evolved from being a way to feed family to a sport or hobby. Who can catch the biggest fish? From my experience tournament fishing can be a challenging but relaxing sport. A good angler knows how to catch the fish but the bass master knows where the fish is.
Since so many people rely on the fish caught around these reefs, limiting stress on them is important. They supply the benefit and necessity of food to many people. In developing countries, coral reefs contribute to one fourth of the fish caught that feed about one billion people in Asia alone (Moore 1). Fish seem to be plentiful, at least right now.

The main biotic factors are the plants, fish, and microorganisms. The plants are the main component of an aquaponic system, and they play a significant role in forming a symbiotic ecosystem, the plants also provide water full of nutrients for the fish. Additionally, the fish play a role in forming the ecosystem, but they also assist in the growth of the of the plants by allowing for clean water to be produced from their waste. The bacteria allow for the nitrification cycle to take place, in turn, cleaning the water in the
There was a technological advance in fishing practices and fishing boats. For example, boat engines became bigger, nets became bigger and able to go deeper, sonar and radar helped fisherman accurately target the fish, huge boats with massive refrigeration systems meant that these boats could stay out for very long time and the only limit to how much fish they could catch was how many fish the boat could hold.  The worst example of new fis... ... middle of paper ... ... levels. The industry group that brings together fishery management is called “The Marine Conservation Alliance” and includes 70% of the industry. This group pushes for fishing reserves based on good scientific catch levels which are environmentally stable.
Some travel beneath the surface to have fun and explore its beautiful habitats. The ocean is an immense structure that sustains life on earth . As such, without the oceans we would not be able to breathe due to fact that various organisms that live in the oceanic environment such as phytoplankton and stromatolites which create oxygen and help us to stay alive and allow .Aquaculture plays an important part in the ocean's services by bringing within the realm of possibility a new way of food production around the world by making sustainable long- term practices available, and food security as well as environmental costs being leveled. Furthermore, when it comes to the worlds food source, we rely on the ocean for ''$21 trillion in food'' , due to fisherman fishing frequently for people's meals and as a means of income. Seafood being a dominant food source in the human race because of its nutritional and abundance of omega 3, protein and other mineral substances that are beneficial to maintain health, therefore, bestows the ocean's additional services upon us.
Separately, aquaculture and hydroponics have negative implications in their systems. However, when fused together in aquaponics, the two systems solve the other’s problems (Blidariu & Grozea, 2011). Aquaponics is an innovative agriculture system that has been implemented from a need to resolve the ailments of the separate systems of aquaculture and hydroponics; this new system has effects that are beneficial to the producer, consumer, and the environment. The growing population of the world has caused agriculturalists to consider new technologies and methods to feed the earth. The population is estimated to “double” by the year “2050”, creating an urgency for these agricultural breakthroughs (Veludo, Hughes, & Le Blan, 2012).
This vegetation also provides much cover for fish. The aquatic plants provide a great source of food supply and act as a nursery for young fish (“Native” par. 5). Vegetation serves many purposes in fish habitat; besides keeping fish safe. It also helps keep the lakes clean.
Antimicrobial resistant bacteria in seafood are a major public health concern worldwide. Reports on use of antimicrobials in aquaculture and residue findings in the products have indicated food safety threat to the consumers. In aquaculture, the use of wide array antimicrobials leading to development of bacterial resistance, use of resistant probiotic resistant strains and contamination of resistant pathogenic bacteria e.g. Salmonella spp. as input have facilitated to development of pool of resistant bacteria.
