First of all, it removes fertilizer and chemicals from the agricultural process. The fish waste acts as a natural fertilizer for the crops, instead. Second of all, it saves water because the water is recycled within the tanks rather than sprayed across a field of crops with abandon. Thirdly, an aquaponics environment can be set up anywhere, so it reduces the need for local communities to import fish and crops from other countries.

Wisconsin has cold winters, and mild summers. Due to the fact that it has cold winters the agriculturists cannot raise certain fish. And the fish they can raise must be kept indoors so that they can harvest the fish all year round.

They have an inverse (negative) relationship.

The aquaculture changes have made steady growth and gain of production in Chinas food and security policy. The fishery sector has benefiting from the early market and price liberalizations.

SIC 0273 applies to ANIMAL AQUACULTURE.

No. Aquaculture refers to a type of agriculture where primarily fish are raised for food.

I believe there are some fish farmers (marketers?) who have Tuna caught live and then keep and feed them in very large enclosures in the ocean prior to selling them in the Japanese live fish market. So it must be possible to keep some Pelagics this way but by their very nature Pelagic fish would not be a natural choice for fish farming.

The problem with Pelagic fish being suitable for aquaculture is what they eat. They require high levels of protein for growth. Also, they have very specific amino acid requirements that are usually only met by fish meal. The amount of fish meal (and its cost) needed to feed them until they are market size makes most pelagic fish not a good choice.

Cultivation of water animals, such as eels and fish

There is the allometric equation which is used to find when is the best time to harvest the fish (or whatever else) so that the cost of production per pound is at it's lowest. Furthermore, there is a ton of statistics involved. Lastly they're are many equations when it comes to spreading of disease, population growth, food and resource consumption. Many of thos equations, if not already given to you, involve a solid background in differential equations. I'm not sure how much detail you want, hope it helps.

Tank size, fish's max. size, preferred water temperature, plant needs, aggression, water chemistry standards, your own fish-keeping experience, fish's preferred food (live, flakes, veggies, etc.), other fish in the tank. these are the most important ones, if you have found a fish you like, go to liveaquaria.com for more info (find the type of fish and read its requirements).Hope I helped!
