Explanation:
The rapid increase in the human population day by day has led to the increased usage of marine plants and animals. Due to this, the population f some marine plants and animals is declining to threatening levels.
To overcome his problem, scientists have devised the method of mariculture. This technique involves raising aquatic plants and animals in artificial lakes or ponds containing salty water just like in the oceans.
Some of these plants and animals are:
- Sea weeds: People might think that they do not consume sea weeds but it is actually present in most of our daily use products like toothpaste, ice creams and even in some automobiles. Many people from the world consume sea weeds as food. Hence, they are being raised in maricultures.

In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.
