1. experimental research method: quantitative or qualitative evaluation and verification of aquaculture technology through laboratory or field experiments. This method can provide accurate data and results, but it needs the design of control variables and random grouping.

2. Observation and research method: Through the observation and record of farms or farmers, we can understand the practical application and effect of breeding technology. This method can get real data, but it may be influenced by subjective factors.

3. Questionnaire survey method: By designing and distributing questionnaires, collect the opinions and experiences of farmers or related experts, and understand the acceptance of aquaculture technology and suggestions for improvement. This method can get a lot of information, but there may be problems of answer deviation and sample selection.

4. Literature review method: By consulting relevant literature and research results, comprehensively analyze and evaluate the aquaculture technology. This method can obtain a wide range of information, but it needs to filter and sort out a large number of documents.

5. On-the-spot investigation method: Through on-the-spot investigation and interview, we can understand the problems and challenges encountered in the practical application of aquaculture technology, as well as the solutions and experiences. This method can obtain direct information, but it needs more time and resources.

6. Model simulation method: By establishing mathematical model or computer simulation, the breeding technology is predicted and optimized. This method can provide theoretical guidance and decision support, but it needs to establish reasonable models and assumptions.

To sum up, the research methods of aquaculture technical papers are various, and appropriate methods can be selected according to specific research purposes and conditions.
