Examples Of Aquaculture

1212 Words5 Pages

Aquaculture in India Aquaculture is the cultivation of the natural produce of water (such as fish or shellfish, algae and other aquatic plants). Mari culture is specifically marine aquaculture, and thus is a subset of aquaculture. Some examples of aquaculture include raising catfish and tilapia in freshwater ponds, growing cultured pearls, and farming salmon in net-pens set out in a bay. Fish farming is a common kind of aquaculture. India offers a huge potential for aquaculture development. The country has a coastline of 7,517 km and an extensive river and canal system of about 195.210 km, consisting of 14 major rivers, 44 medium rivers and numerous small rivers and streams. In addition, pond and tank resources are estimated at 2.36 million ha.1 India experienced an eleven fold increase of fish production in the past six decades. This growth continues as is demonstrated by figure 1. In the freshwater, brackish water and the marine aquaculture sector there exist challenges and opportunities to which Dutch companies can respond. History Aquaculture was used in China circa 3000 BC. When the waters lowered after river floods some fishes, namely carps, were held in artificial lakes. Their broods were later fed using nymphs and feces from silkworms used for silk production. The Romans were quite adept in breeding fish in ponds. …show more content…

Organic wastes from fish cages can have a significant effect on water quality and the population structure of organisms, beyond the boundaries of the fish pens, increasing the occurrence of toxic algal blooms. Scotland, as well as Chile and China, has had serious toxic algae blooms. Algal blooms can cause the death of huge numbers of wild fish and other species, and great harm to wild fisheries. However, even a month of fallow time can return the area to pristine

  • Crayfish Case Study

    235 Words  | 1 Pages

    Crayfish are decapods pertaining to the phylum arthropoda, which are invertebrates and contain an open-circulatory system.1 The system works by the hemolymph getting re-oxygenated in the gills before being transporting to the heart by brachio-cardiac veins and then pumped to sinuses that bathe tissues with oxygenated hemolymph.2 The crayfish contain a neurogenic heart that depends on neuronal input from cardiac ganglion.3 The neurogenic heart requires nerve impulses to produce contractions in contrast to a myogenic heart that can contract independently from the nervous system.3 The crayfish heart will beat due to the reaction of the ganglion to stimuli in the environment.4 Stimuli will affect the autonomic nervous system in the crayfish that control involuntary actions such as the heart rhythm.4 Neurotransmitters are the chemical signals in which the nervous system regulates both heart rate and contraction.3The autonomic nervous system breaks into two categories as parasympathetic system that is involved in relaxation of organs and the sympathetic system that will stimulate increased activity. Neurotransmitters can either increase or decrease heart rate by altering the patterns in neural activity of the heart.4 Crayfish are poikilotherms, which means they cannot metabolically thermoregulate thus conform to the ambient temperature in the water.

    Study of Hawaiian Fish by Hubert Vos was created in 1898. It is an oil on canvas, seventeenth century style Dutch still-life painting that depicts a elderly Hawaiian fisherman emptying a lauhala basket filled with bountiful catch of fifty-seven varieties of fish native to Hawaiian waters, carefully rendered from sketches of fish commonly displayed in the Honolulu Fish market, on a marble slab.1 I propose that this is work is a piece of art Hawaiian art because it portrays the ancient Hawaiian art of fishing, displays staple native fish that were important to the diet of ancient Hawaiians along with the ancient art of lauhala basket weaving . The reason why I chose this specific piece of art to write about is because it caught

  • The Role Of Water Pollution In Ohio

    The algae comes from fertilizer that washes in the water from huge farms near the lake. The algae absorb a lot of oxygen from the water when they run out of steam and leave spots called “Dead Spots” which are areas where there is no oxygen so fish can’t breathe. Though this isn’t even the worst part, some of the bacteria that are in the algae get into our water and cause nondrinkable water. If someone were to drink it, they would get very sick and maybe have fatal outcomes. All hope is not lost though because Scientist are working very hard to solve how we can clean the lake.

    The purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.

    When one thinks of a veterinarian, most associate this job title with treating dogs, cats, horses, cows, and other farm and companion animals. However, a relatively small field not known by the general population is that of marine veterinary medicine. If one has a passion for the water and a desire to help the creatures in it, marine veterinary medicine just may be the perfect career. Marine veterinarians are responsible for “conducting basic exams and evaluations, giving vaccinations, taking samples of blood and other bodily fluids, prescribing and distributing medication, evaluating behaviour, performing surgical procedures, and taking x-rays and sonograms” (Kramer “Life of an Aquatic Veterinarian”).

  • Consequences Of Overfishing

    800 Words  | 4 Pages

    According to world wildlife organisation, overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results may not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life. According to the research world wildlife organisation, 1.6% of the world’s oceans have been declared as marine protected areas (MPAS), and 90% of existing MPAS are open to fishing.

    While researching about how pollution affects sea turtles, we faced some issues on finding different types of pollution. As most people know, the plastic waste that is being dumped into the oceans and onto the beaches is becoming a main food source for sea turtles. When sea turtles see this trash, they consume the plastic causing death or severe sickness which has caused this species to become endangered. They also get tangled with the plastic in the ocean restricting them from normal movement and function. During our research, we found that there are more types of pollution affecting sea turtles than just plastic waste in the ocean.
