Barramundi Aquaculture Definition

Brine Shrimp are a micro-crustacean that is found mostly in inland saltwater bodies, however, the salinity levels that they live in vary greatly. The conditions that they require can be made at home as the eggs (cysts) of the shrimp are dry, hard shells that can withstand drought and go without water for up to 50 years. This study presents the results of 3 different salinity levelled environments to the Brine shrimp in order to discover a salinity level that produces the most successful hatching rate. By filling 3 Petri dishes with 20mL’s of purified water, each dish contained varying sodium chloride amounts from 15ppt, 25ppt, and

Aquaculture can be defined as farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants both in freshwater and saltwater. It has a wide range of ownerships from small family business to multimillionaire global industries.1It provides many job opportunities throughout the world. As an example Canadian aquaculture industry valued $ 5 billion Canadian dollars provides more than 130 000 jobs only in Canada.2Accelerated growth of aquaculture causes series of problems to both human health and environment.3Most bacterial species resides both in animals and well as in human will pathogenic to both. transfer of pathogens between the two host species is a common situation for most organisms.4 Most of the developing country aquatic farms are non-hygienic and stressful. This will lead to an increase of bacterial infection among most aquatic species. As a preventative and curative method farmers mix a huge amount of antimicrobial products with the aquatic feed.5 Since aquaculture is a global industry, Implemented laws and regulations are different from country to country. It is very difficult to implement global regulations relating to antimicrobial use.1

The purpose of this lab was to answer the question, “Of the saline solutions of 0%, 0.5%, 1%, 1.5%, and 2% sodium chloride (NaCl), which solution will yield the highest hatching viability for the brine shrimp?” The hypothesis was that the saline solution most precise to the concentration of NaCl in seawater, which is approximately 3.5%, will yield the highest hatching viability. Therefore, the 2% NaCl solution will yield the highest hatching viability.

One of the most commonly shared beliefs about aquaculture is that it has potential to amplify and transfer disease/parasites to wild fish populations, but strict management practices and guidelines have been utilized and supplemented to ensure that US farming operations mitigate current and potential environmental risks associated with aquaculture (NOAA, 2015). Among these practices are regular diver-led inspections to investigate the integrity of nets and net infrastructure, surveillance cameras and even public webcam feeds that monitor the fish farms and in particular monitor efficient use of feed, regular health inspections in efforts to have a head start on disease prevention and detection, and “comprehensive sanitary and biosecurity programs to prevent the introduction and/or spread of pests or diseases from one farm site/cage to another or into the environment.” (NOAA, 2015). Additionally, movements are being made to stop the spreading of disease and to limit oceanic pollution by containing salmon in solid tanks rather than in netting. “In Washington State, Domsea Farms has launched a land-based, freshwater system to produce coho salmon.” (David Suzuki Foundation, n.d.) This method is not only environmentally sound, but it opens up aquacultural boundaries. By containing fish in these large tanks, there is potential for salmon aquaculture to

The conditions that the captured killer whales are forced to live in are not acceptable replacements for the wildlife habitats that they have been ripped from. All the enclosures that the orcas are kept in do not provide an adequate amount of space that the animal requires. The size of an orca in relation to the size of the tanks they are forced to live in is comparable to the

Behavior of Brine Shrimp in Habitat Selection Introduction: This experiment was developed primarily to find the optimal or preferred living conditions of adult brine shrimp. In this lab 3 variables were tested in different degrees to determine which the shrimp prefer. The different variables were light, ph, and temperature. From outside resources I have found that brine shrimp can survive in temperatures ranging from 4° Celsius to 40° Celsius with an optimal temperature of 20°-25°. So I hope to reinforce this research by testing its validity in the lab. From another outside source brine shrimp display positive photo taxis, which means that they are attracted to light. And finally from my last outside source I have found information that

dangerous in captivity, there are some whales that weigh up to 13 thousand pounds in captivity,

As time goes by developed countries pay great amounts of attentions to fish stocks and the consumption of fish species. These numbers are very important to environmentalist because it helps the government set percentage quotas to keep the fish species in good

Bull sharks migrate often when they run out of food or if the water gets too cold or too cold. Bull sharks like warmer waters that are shallow and about 70 Degrees Fahrenheit.The South American bull shark migrates about 2300 miles a year up rivers and streams.

The habitats that are exploited to farm fish are becoming ineffective, as a result of disappearing mangroves. Humans should be protecting wild fish instead of over farming them. The issues caused by aquaculture are rendering the ecosystem unsustainable. In this chapter, we learned about aquaculture and all the various problems that come with it.

REMIEDIATING AGRICULTURAL WATER CONTAMINATION Remediating Agricultural Water Contamination: Problem, Solution, and Barriers Paper Problem Concerns about water pollution are generally focused towards sources that are highly visible and chemically oriented. However, the greatest causes of water contamination and quantity abuse in the United States come from agricultural production (United States Environmental Protection Agency [EPA], 2012a), which is defined as a nonpoint source that pollutes with nutrients. In 2011, nine

Blue Whales are endangered and their numbers are slowly going up but it doesn’t mean that they are also getting killed. This animal is found North Pacific, Pacific Ocean, and the Indian Ocean. The blue whale is currently endangered, and it weighs approximately 300,000 pounds or 150 tons! The blue whale is carnivorous and it can eat about 8,000 pounds of krill a day. The blue whale’s life span can be up to 80 to 110 years pretty similar to humans. The blue whale can be up to 100 feet long but they are usually are 60-80 feet long. When baby blue whales are born they are usually 20-25 feet long and can drink up as much as 200 pounds of milk a day. The blue whale is the biggest animal to have ever live on earth. The baby blue whale can be dependant

A fishery by definition, is “the occupation, industry, or season of taking fish or other sea animals (shrimp, squid, clams) and selling them for profit” (Webster Dictionary). Atlantic Cod used to be considered as one of the richest fisheries in the world. Atlantic Cod, scientifically known as,Gadus morhua, are heavily bodied, blunt snouted fish that are typically brown or grayish in color with a series of spots located on their bodies along with a pale lateral line. This species of fish have a schooling behavior when feeding but remain isolated when traveling. The Atlantic Cod once densely populated the waters of the Atlantic ocean, from Greenland to North Carolina. Despite the wide range in location, Atlantic Cod are a nonmigratory species

Another global effect of overfishing is fish farming or aquaculture. It was first started to help preserve the ocean and hoped to help people to obtain a reliable fish source. Unfortunately, what many came to realize is the downside of fish farming. One example is water contamination, where consequently waste products such as foods eaten, feces and other dead fish, are all dumped into our main water supply which contributes to water pollution. Moreover, chemicals that are used to treat the fish farms like antibiotics and algaecides are all released into the ocean; which is a real cause for concern for our oceans. Fish that come from the fish farms are pumped full of drugs, to prevent sickness in the fish but this is not healthy for us to eat. There is also a great environmental impact which includes the fact that to sustain fish farms, portions of

Due to the importance of fishing to the worldwide economy and the need for humans to understand human impacts on the environment, the academic division of fisheries science was developed. Fisheries science includes all aspects of marine biology, in addition to economics and management skills and information. Marine conservation issues like overfishing, sustainable fisheries and management of fisheries are also examined through fisheries science.
