Marine fish nursing and culture techniques

Semester: June

 

Course Objective: The demand for marine fish has been increasing, meanwhile the limitation of marine fisheries yield has been known worldwide. Many countries and territories around the world therefore are focusing on developing marine aquaculture to balance the human demand and the conservation of marine resources. In the other word, the demand for marine fish can only be met fully if marine aquaculture considerably contributes to the volume and stability of global marine fish supplies. The techniques for marine fish nursing and culture have been studying and developing to meet this inevitable requirement.

 

Learning Outcomes:

On completion of this course, students will be able to:

-          understand the certain marine fishes biology

-          apply artificial spawning technique

-          apply nursing technique

-          apply growing out technique

-          carry out harvesting and transporting techniques for fingerling and marketable size fish.

 

Pre-requisite: None

 

Course Outline:

 

1. Introduction to marine fish nursing and culture; evaluation of status, prospects and constraints of marine aquaculture

2. Biological characteristics of common culture marine fish species (cobia, grouper and threadfin)

3. Hatcheries techniques of marine fishes

4. Nursing and culture techniques of marine fishes

5. Techniques for harvesting, transporting of fingerling and marketable fish

 

Laboratory Session:

1.    Examine biological characteristics of cobia (appearance, stages of development, gonad...)

2.    Examine biological characteristics of grouper (appearance, stages of development, gonad...)

3.    Examine biological characteristics of threadfin (appearance, stages of development, gonad...)

 

Field visits:

1.      Field trip to marine fish hatchery

2.      Field trip to marine fish growout farm

Teaching and Learning Methods: Lectures, field visits, case studies and presentations (description attached)

 

Time Distribution and Study Load:

Lecture hours = 45 h.

Field trips = 2 days

Internship / field work = 3 months

Self-studies = 90 h.

 

Evaluation Scheme: 

 

Laboratory report = 5%; Field trip report = 5%; Field work report and presentation = 45%; and Final examination = 45%.

 

Students who display a thorough knowledge on techniques of marine fish nursing and growout during the examinations, and show excellent practical skills in laboratory report and field work report (written report + presentation) are given an A grade, and those who display a good understanding and practical skills are given a B grade.  Grade C will be awarded for those who show below average knowledge and practical skills on the subject matter, and the grade D will be given to students who show poor understanding/ practical skills on the subject matter.
