Tons and Tons. The sea's supply is reducing and fishermen of every nation are finding it more difficult to meet the demand. Fish farms are not filling the gap and even sports fishermen are finding it difficult to catch their limit.
OverfishingOverfishing, or harvesting fish faster than they can be replaced by reproduction, greatly reduced the amount of fish in parts of the world's oceans.
Having several layers of gills on the fish helps to increase the breathing rate of the fish.
The zebra fish will have a higher respiration rate
As the temperature changed, the fish's breathing rate increased or decreased accordingly.
Fish do not have a pulse rate in the same way that mammals do. Instead, their hearts beat at a steady rate that varies by species. Generally, a fish's heart rate is much slower than that of a mammal.
The number of fish that die each day can vary greatly depending on factors such as fish population size, habitat conditions, and care provided. In natural ecosystems, the mortality rate can be quite high due to predation, disease, and environmental factors. In aquariums or fish farms, the mortality rate is often lower due to controlled conditions and care provided by humans.
Sustained yield management is the use of renewable resource of a rate that allows the resource to renew itself. for example, the number of fish caught should not be greater than the number of fish reaching maturity.
The fish population goes into decline and the fish species may go extinct.
Fish and chips
The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.
