What are the negative impacts of fish farming?

Answer 1

Disadvantages: Long hours, high amount of money involved in growing and maintaining the farm, many things can go wrong at a time, meeting quota standards. Cattle can become ill or disease spread, herd requires more feed and nutrients than that of a beef herd.

Advantages: Income is usually higher than beef farming, you have an income everyday (unless something is wrong with the milk or cattle), your day is never the same as the day before.

Answer 2

Advantages

Produces high yields despite small volume of water.

Contains Essential nutrients, with a high protein value and low to moderate fat in comparison to terrestrial animals.

Easily-maintained, requires much less less attention than cattle and other farm animals

Part of an aquatic food chain, therefore it is not taking prey from omnivorous and carnivorous predators.

Disadvantages

Fishing costs (most of modern fishing utilizes technology such as weights, nets (e.g. purse seine), seine nets (e.g. beach seine), trawls (e.g. bottom trawl), dredges, hooks and line (e.g. long line and handline), lift nets, gillnets, entangling nets and traps

Aquatic contamination and pollution:(e.g. Oil spills,human material thrown in water often harms fish)

High density to volume ratio, fish often clustered together thus causing high stress level which increases susceptibility to disease and transfers disease at an accelerated

Mercury: Fish and shell-fish are able to concentrate mercury in their bodies, due to this being a toxin it can show negative effects if it is consumed.

Answer 3

Some advantages of dairy farming are that farmers get to be independent and work outside much of the time. Among the disadvantages are the fact that dairy farmers are at the mercy of the price of milk and must also depend on the weather to allow them to get hay and grain affordably. When things go wrong it can add up fast and drive dairy farmers out of business.

Answer 4

Fish farming can cause pollution to surrounding waters. Uneaten food pellets from fish farms alter the organic matter in the water which can change the consumption of oxygen and cause local eutrophication (there is too much algae in the water that becomes dominant and kills other animals and species).
