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

3. Hatcheries techniques of marine fishes
4. Nursing and culture techniques of marine
fishes
5. Techniques for harvesting, transporting of
fingerling and marketable fish
