The UN Environment Programme estimates that about one million seabirds and 100,000 marine mammals every year are killed by plastic debris, which can include not just plastic bags, but syringes, cigarette lighters and toothbrushes, all of which have been found inside the stomachs of dead seabirds.
The general "fish deaths" number has never been calculated.
To calculate the number it would be necessary to determine:
This is far more than a life's work. Additionally, the data would be changing as fast as you could collect it. And this is precisely the problem with assessment of the pollution of our oceans. Pollution is massive (consider the North Pacific Gyre), and there isn't a good way to "get a handle on it" in an attempt to affect changes. The problem is just "out there" and bringing it home takes massive effort.
Fish deaths and that of other sea creatures are being magnified by the current oil spill catastrophe in the Gulf of Mexico. No telling how much time will be needed for the waters to become clean enough to sustain and reproduce marine life.
I can exactly answer that question, but here is a website if you are worried about water pollution killing innocent animals: http://www.promotega.org/GHC06004/index.htm it is mostly for kids, but that doesn't mean you cant help out in the same way! Answer: The term fish can be applied to a number of life forms from minnows to basking sharks. Specific fish related death rates are occasionally developed for rare, endangered or "cute" critters, usually after an oil spill. The general "fish deaths" number has never been calculated.
To calculate the number it would be necessary to determine:
* Number of fish of the species alive at any given time. * Total mortality rate from all causes. * Percentage attributable to pollution. This is far more than a life's work.

It is in excess on 250 000 000 kg (280 000 tons) per day. It could be (by estimation!!) at least 100 000 000 fishes every day.

Pretty sure it's around 20-30
Over 1,000
normal rule for fish in a tank is: For every 1 inch of fish there is 1 gallon of water
Half of 10 gallons is 5 gallons, there are 4 quarts in a gallon, and 5*4 is 20.
Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.
no fish do not like dirty water you will be able to know because if it is a colorful fish the fish will not show that many colors and bold color fishes will be lying down on the rocks and look dead
Many tetras prefer soft and acidic water.
The pollutants react with the oxygen dissolved This means there's no oxygen available for the fish. That kills more fish than the actual toxicity of the pollution in many cases.
There are no statistics available regarding how many fish were killed from Titanic pollution. It is estimated that approximately 100,000 sea mammals die from pollution each year.
You need about one gallon for every inch of fish you have
From natural causes (Including predatory fish, old age, illness or disease)- approximately 1254865 From mankind (Including fishing and pollution)- approximately 856234
normal rule for fish in a tank is: For every 1 inch of fish there is 1 gallon of water
More than 20,000 can die with water pollution
There are 4 types of pollution in the environment. These include Air pollution, water pollution, noise pollution and soil pollution.
1. Why water pollution is a problem? Because, water pollution kills. It kills the fish and all living beings that lives in the water. If all the water life is dead so will much of humans food source will die too. 2. How Many People Pollute Each Year? Millions of people pollute each year. 3. How a ocean can get contaminated? water pollution, oil spills/leaks, people throwing litter into the ocean. 1. Why does water pollution affect all living beings? Because, contaminates our bodies and many of animals habitats.
Most of Kenya's pollution effects; are mainly air pollution, it mostly comes from gas, or transportation vehicles that use gas or some sort of energy, the effects are; that many people die from pollution in the air because, the chemicals in the air kill many people, as well as animals, water pollution kills fish, plants, and other under-water animals. It kills them because of all the waste, garbage, and chemicals you throw into the ocean. It also can injure many animals.
Dpends on the size of the fish its one inch full grown for every gallon
Water pollution has many harmful effects on society. Even when the water evaporates the pollutants still remain.
there are many types of pollution the main ones are- noise, air, light, water and land
