Answer 1

try wikipedia it has a huge article on illegal fishing beleive it or not also it has ways that fishing techniques vary through out the word but the ones are dynomite electro fishing etc
Dynamite or blast fishing, is done easily and cheaply with dynamite or homemade bombs made from locally available materials. Fish are killed by the shock from the blast and are then skimmed from the surface or collected from the bottom. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can damage or destroy the physical environment. Explosions are particularly harmful to coral reefs. Blast fishing is also illegal in many waterways around the world.

Electrofishing
A relatively new fishing technique is electrofishing, typically used for stream classification surveys and catching brood stock for hatcheries, or making estimates of populations in a body of water. A gated pulse of direct current is used to cause muscular contractions in a fish, called galvanotaxis, causing them to turn towards the source of the electrical current and swim towards it when correct pulse speeds and durations are used, along with correct current.

A low voltage or short pulse with long gaps will cause the fish to swim away from the device, and high voltage or long pulses with short rests can cause galvanonarcosis, or unconsciousness. Techniques for setting pulse length and patterns, current and voltage require great skill to catch fish effectively without killing or injuring fish if they are to be left unharmed. Dissolved minerals in the water can decrease resistance causing less of the current to pass through the fish, whereas fish recently entering fresh water from the ocean have high salinity and are more prone to electric shock. Also the smaller the fish, and consequently the less surface area in contact with the water, the higher the current required to produce galvanotaxis. Smaller fish also require shorter pulses, closer together, while large fish should have longer pulses at lower power and longer gaps between pulses.

Rigs can be battery powered back-packs or powered by a generator if they are mounted in a boat. They are typically equipped with a "dead-man switch" and a tilt switch to disable the device if the unit is tipped or the operator incapacitated. Protective equipment must be worn to isolate the operator and prevent electrocution.

Electro-fishing is also used to illegally catch Razorfish or Spoots, using a boat based generator. Current is passed into the sediment causing the Razorfish to 'jump' and be harvested by divers. This method of electro-fishing is banned due to the risk to the divers.

Answer 4

Gill nets on inland water ways or lakes, in the United States. This means rivers, streams, and lakes. Some Native American Nations (tribes) are excluded from this law.

Electro shocking any body of water in the United States other than the Fish & Game departments for fish study.

Some states do allow "snagging" I know there is a season for it on the Ohio River.

Answer 5

How many different type of fish are there in the ocean? Nobody knows because new fish are being discovered every minute and old fish are dieing out. .

Answer 6

dead lining is illegal in most parts of the UK now but allot of polish and eastern European people have come over to this country and started it up again they will take any kind of fish. what you do is stick a bait on a strong line and leave it in the water say over night and the fish can pick up your bait possibly five Minuit's after you go and be fighting against your line all night which tires the fish out sometimes it will even kill the fish through exhaustion

Answer 7

snagging - where you use a big 3 way hook and try to catch the fish by lodging the hook into the fish by yanking on the rod.

net fishing - where you open a very large net - drag the lake and pull all species of fish from the water.

electrocution - obviously not smart - or legal

Answer 9

Using the leaves of the common mullein plant or walnut hulls to paralyze the fish's gills, or the use of traps and shooting with firearms are illegal in my state.

Answer 10

Run an electric current through the water. The handcrank generator that used to be used for military radios is usually what is used.
