Have you ever wondered how many fish live in a lake or river? That is something scientists and fish managers think about a lot! They want to know how many fish there are swimming about so they can tell if the fish population is healthy and decide how much fishing people should be allowed to do. However, all that fish is hard to count! There is a dedicated way to do it, and this involves using something called a fish counter.
Fish counters are a really valuable piece equipment for counting the fish living in water body. This information is important for scientists and fish managers to understand whether there are enough fish in the water so that it remains healthy, or if people can catch from the population without harming them. Too many fish in the water is unhealthy for ecosystems and not enough tells us that our fish are running into extinction.
Given that some fish are endangered, the use of a fish counter can be extremely useful for tracking them and understanding their numbers. Scientists can then use these results to determine if the numbers of those special fish are growing, or shrinking over time. If they notice too many of a certain fish are going away, then the begin a campaign to save it from becoming extinct.
There has been a long history of change in the design and construction of fish counters. People used to keep a paper and pen way back in the day, just to count the fish. But now, with the advent of modern technology, fish counters can come in many forms and use everything from cameras to lasers to even sound waves (hydroacoustic surveys) for counting fish.
A little different from the laser system. They flash a beam of light into the water, and when fish swim through it they interrupt that beem. This light break will give the approach to count how many fishes are down there. While this approach yields very accurate, robust numbers it can be quite expensive to implement.
In order for fish counters to be useful resources, they must perform accurately and consistently. And by accurate we are saying the numbers they provide us have to be right. And by steady we mean, the numbers should consistently remain that low. A fish counter cannot be wrong or a fish manager if it is not stable; the data that will remain from there are meaningless and unusable for scientists.
Having a device called the fish counter will help you tally up how many fish are there in your current reservoir results. Fish counters can be configured very quickly since there are a number of excellent technology options available to choose from today. They are able to sample a lot of individuals very quickly, which allows scientists to make better decisions regarding the population status.
