These eggs are cared for and are provided with the essential things such as nutrients and correct temperatures in which to thrive. The fish are born and raised to a certain stage and then are moved to open waters or such places as lakes, streams, and ponds. In this way these habitats are provided with ample supplies of fish and other marine organisms. Another method involves the use of enclosures and retainers. This certain method can be described in three separate ways, natural feed, supplemental feed, and no natural feed. The natural feed method works by separating the desired fish and the food providers of the fish from there predators in there own natural waters by the use of netted embayments and cages, thereby allowing the provider to grow and multiply in its own habitat and this in turn allows the fish to multiply. The second way is supplemental feed and this method works by isolating fish in tanks or concrete ponds. In these tanks or ponds fish are reared through the use of supplemental feeds along with natural feed that is pumped in from the sea. This allows the fish to have a lot of food supply making sure the fish get nice and fat for the market that they are being primed for. The third method works much like the second involving the tanks and ponds but this time there is no natural feed pumped in instead fertilizers take the place of natural feed along with ...

    Antibiotic Abuse In Animal Agriculture Exacerbating Drug Resistance In Human Pathogens

    6658 words - 27 pages

    Abstract (Summary) Most of the antibiotics produced in the U.S. are fed to farm animals routinely as "growth promoters," and to facilitate "factory farming." Unfortunately, this places selective pressure on bacteria to develop antibiotic-resistance. Genes that neutralize antibiotics wind up protecting disease-causing germs. We have seen a tremendous increase in antibiotic-resistance in common food poisoning bacteria like Salmonella, but the problem is even worse than food-borne diseases. Bacteria also can rapidly transfer and spread antibiotic-resistance to other bacterial species. Therefore,
