AQUACULTURE EXPOSITION


 

Introduction:

Aquaculture is the farming of aquatic lives like fish, crustaceans, mollusks and aquatic plants. It is a properly planned farming that is held under mild conditions. Farming suggests some form of intervention in the rearing process to increase production, such as regular stocking, feeding, protection from predators, etc. Farming also suggests the individual or corporate ownership of the stock being cultivated for some time. Moreover, in current aquaculture practice, products from several pounds of wild fish are used to make one pound of a piscivorous fish like salmon. It may involve many other framings as well. Special kinds of aquaculture include fish farming, shrimp farming, oyster farming, mariculture, algaculture and the cultivation of ornamental fish. Special methods include aquaponics and integrated multi-tropic aquaculture, both of which integrate fish farming and plant farming.

Harvest stagnation in wild fisheries and overexploitation of popular marine species, mixed with a growing demand for high-quality protein, supported aquaculturists to breed other marine species. At the inception of modern aquaculture, many were optimistic that a Blue Revolution could occur in aquaculture, just like the Green Revolution of the 20th century had revolutionized agriculture. Though land animals had long been bred at homes, most seafood was still caught from the wild. Concerned about the impact of growing demand for seafood on the world’s oceans, prominent ocean explorer Jacques Cousteau wrote in 1973. With earth’s burgeoning human populations to feed, we must turn to the sea with new understanding and new technology.

Consequence and significance:

Almost 430 (97%) of the species produced as of 2007 were bred at home during the twentieth and twenty-first centuries, of which an approximate 106 appeared in the decade to 2007. Given the long-term significance of agriculture, it is crucial to note that to date only 0.08% of known land plant species and 0.0002% of known land animal species have been domesticated, as compared to 0.17% of known marine plant species and 0.13% of known marine animal species. Domestication usually involves about a decade of scientific research. Domesticating aquatic lives take fewer risks to humans than do land animals, which took large money in human life. Most major human diseases began in domesticated animals, including diseases like smallpox and diphtheria that like most pernicious diseases spread to humans from animals. No human pathogens of comparable virulence have yet appeared from marine lives.

Biological control methods to administer parasites are already being used such as cleaner fish to control sea lice populations in salmon farming. Models are being used to help with spatial planning and siting of fish farms to minimize impact.

The decline in wild fish stocks has supported the demand for farmed fish. However, it is necessary to find alternative sources of protein and oil for the fish feed so the aquaculture industry can grow sustainably; otherwise it represents a great risk for the over-exploitation of forage fish.

Another recent issue following the banning in 2008 of organ tins by the IMO (International Maritime Organization) is the need to find environmentally friendly, but still effective, compounds with antifouling effects.

Aquarium Roofing

Roofing For The Aquarium

roofing-companiesSo we all know that roofing is extremely important for our homes. It protects us from the elements and contains everything we need. If you get the wrong roof, you are going to be replacing it constantly. Get the right one and you won’t even need to clean it regularly. Yep you can have a self-cleaning roof. Now, let’s take that a little further. Your aquarium needs a roof, too.

Roofing Company Considerations

Really the roof is going to serve a completely different purpose than your roof. That does not mean that the roof is any less important, or that the roof is going to be easier to pick. So begin by what type of fish you have. Some type of fish need a specialty roof.

roofingRed belly Pacus, for instance, can get up to 20 lbs. Well, they can get bigger but that depends on the aquarium you have them in. If you do not have the proper roofing, they will either jump out or they will not have the air flow that they need to thrive. Trust me, the wrong roof and they are just going to go through it like it isn’t even there.

Victoria BC Roofing For Outdoor Aquarium

If you in Victoria BC Canada and have an outdoor aquarium, you will need a roof as Victoria can get quite chilly in the winter. There are many reasons for this, but the main on is that you have to be able to control the temperature. These same principles also apply to Nanaimo BC Canada. The material that your roof is made out of will help you to do that, but it will also keep the wind from blowing on it. Keeping the wind and rain out of aquarium can help regulate it by about 10 degrees. This is especially true if it is in underground aquarium. You’ll want to be sure to look for a

roofing-companyThe difference between an outdoor, in ground aquarium and a pond is really the roof and the pump. Most ponds do not take a pump and the fish are generally a hardy breed that is weather resistant. The in ground aquarium is going to have an elaborate pump system, a device to control the temperature, and a roof. The roof is your first defense against anything you do not want in your tank, including birds. Your roofing options are going to vary by as much as your fish options. Talk to a specialist about what your fish need and then the options will become easier for you to choose from.

Basically, your aquarium is your fish’s home. Treat it as you would your own home and do not take your roofing choices lightly.
