On top of this, water quality will deteriorate causing more stress and health issues. Another important factor in fish health is good oxygen levels. Aquariums that have a larger surface area have better gaseous exchange, therefore better oxygen levels in the water.

For example, a tall, slim 30 litre aquarium that has a small water surface will generally have poorer oxygen levels than an equivalent volume model with a wider surface opening. The New York Times.

Scientists have been working to develop new efficient methods to count fish such as the use of Artificial Intelligence.

The data collected is fed into a computerized system for easier analysis. It is from this data that estimates along with other information are deduced. Taking stock of the number of fish in the ocean is an essential task. It is important to determine the amount of fish available so that it can be estimated how many of them can be taken out for the population to remain sustainable.

The records portray whether fishery management goals implemented are efficient and shed light on the fishery trends.
