Describe the extent of infection as a result of catches, as well as how release techniques have led to the decrease of the red rum fish by 20 percent.

Research Design Plan
The main aim of this study is to find out the extent of infection as a result of catches, as well as how release techniques have led to the decrease of the red rum fish by 20 percent. The investigation of the decline took place between 2002 and 2007 in South Texas State. There is the need to identify a suitable and appropriate research design that will yield expected results. This study intends to use the quantitative research technique; it is a research tool that attempts to gather data by objective methods to provide information about relationships, comparisons, and predictions (Muijs1). Besides, it tries to eliminate the investigator from the investigation. One common factor in all quantitative experiments is that they all use a standard format for generating a hypothesis that is approved or disapproved. The hypothesis must have the ability to be proven mathematically or statistically as it is the basis of the experiment’s entire design. It involves randomization of study groups and the inclusion of control groups wherever possible.
Quantitative research has some advantages when adopted for use in any research. Firstly, it provides an excellent way of finalizing results by proving or disproving the hypothesis (Muijs 2). Secondly, the results from any form of quantitative research are real and unbiased; they can be legitimately discussed and published by peer groups. It is also useful for testing results gained by a series of qualitative experiments. Despite the various pros of quantitative research, there are also some cons associated with this method. The first disadvantage is that they may be difficult and quite expensive to conduct. Secondly, it requires the use of statistical analysis that may be difficult to non-mathematicians (Muijs 2). Thirdly, money and time must be invested to fine-tune the results due to some ambiguity that may arise. Finally, it generates results that are either proven or unproven and leave no room for any uncertainty.
Experimental research is a form of quantitative research that involves maintaining control over all factors that may affect the findings of an experiment. In simple terms, the researcher attempts to find out or predict what may occur (Bryman and Bell 163). It is a primary form of data collection as the results are obtained from the study’s subject directly. An experimental design is a roadmap of the procedure that a researcher follows to test the hypothesis by reaching valid conclusions about the relationships that exist between independent and dependent variables. Besides, it elaborates the conceptual framework of conducting an experiment. This research will employ the use of an experimental research design.
Experimental research design attempts to predict events that will occur in the experimental setting by neutralizing the effects of other factors. It is a manipulation of an independent variable through control and observation (Bryman and Bell 165). Control involves trying to hold all other variables except the dependent variable constant. Observation, on the other hand, entails the manipulation of independent variables on the dependent variable. In this research, the independent variables include the extent of infection as a result of catches and release techniques. The dependent variable is the decrease in red rum species of fish. The advantages of this design are that there is better control of the variables, easy determination of cause and effect, and better results (Bryman and Bell 145). The method, however, has some disadvantages. Firstly, it is subject to human error that affects the efficiency of outcomes. Secondly, one can fail to do the experiments as one cannot manipulate independent variables due to ethical issues. Finally, the research design sometimes creates artificial situations. The method of data collection will include the use of questionnaires and observation.
