Aims

Aims at introducing the students to the wide diversity and variability existing in fish reproduction and sexual determination and differentiation processes; offering to the students basic knowledge on endocrinology of marine fish and shellfish; showing the students the effects of environmental pollutants on endocrine system and reproduction of fish and shellfish; developing skills to estimate reproductive stages in fish and shellfish; and understanding modern tools on aquaculture of fish and shellfish species.

Objectives

1. Understand reproduction strategies in fish
2. Identify reproduction strategies and reproductive gonad stages in fish and shellfish
3. Have gained a knowledge of impact of environmental pollutants on fish and shellfish reproduction and endocrine system, as well as of hormonal regulation in aquaculture.

Key skills acquired

At the end of the Unit the student should identify sex and gonad development in fish and shellfish and identify effects of pollutants in reproductive and endocrine system in fish and shellfish
