Marine invertebrate biology and culture
Run by School of Ocean Sciences
20.000 Credits or 10.000 ECTS Credits
Organiser: Prof Lewis Le Vay
Overall aims and purpose
The module aims to provide an understanding of the biology, ecology and culture of a range of marine invertebrate species and the application of this knowledge in the culture of selected commercial species. These specific aims are:
1) To develop knowledge and understanding of the life cycle of selected species and groups.
2) To develop knowledge and understanding the principles controlling larval supply, recruitment and abundance of natural populations.
3) To understand the underlying biological characteristics of marine invertebrates that determine their suitability for culture.
4) To develop knowledge and understanding of culture techniques for a range of commercially important species and groups and principles of hatchery design.
Biological and ecological aspects of the life cycle of selected species will be covered in detail, including reproductive biology, larval development, larval feeding and nutrition. Factors controlling larval supply and recruitment in natural populations will be considered. Current status of aquaculture for invertebrate species will be reviewed, moving on to biological criteria for selecting species of aquaculture and culture practices for a range of commercially important species. This will include all aspects of larval and growout culture for molluscan and crustacean shellfish from water quality management, live food production, broodstock selection and management, spawning induction, handling gametes and embryos, larval development and growth. Grow-out production systems from extensive to intensive will be covered.
Rudimentary report containing the very basics of what was done, but missing detail and with only the simplest analysis. Design and layout of report acceptable.
Report sufficiently introduced and referenced and containing the important details of material and method, with tabulated and/or graphical presentation of data obtained and a concise but sufficient analysis of the data. Short but pertinent discussion with a few papers referred to. Design and layout of report reasonable
Outstanding report having a concise introduction covering all relevant aspects of the study and giving full references. Materials and methods fully and succinctly described, data well presented in tabular and/or graphical format, data fully analysed using the correct analytical methods for all data sets. Discussion focused, critical and concise, covering all aspects of the study, and fully referenced. Design and layout of report exceptional.
Understand the principle components of a marine invertebrate hatchery and conceptual design principles.
Understanding of the biology, life cycle and ecology of a range of marine invertebrates
Understanding and knowledge of principles for selection of species of aquaculture and aquaculture practices for a range of commercially important species.
Ability of handle and analyse data, and writing of an interpretive report in the context of primary research literature.

Teaching and Learning Strategy
Lectures 20 Hours
Directed study: Each lecture topic will have associated reading material which will be book chapters, reviews and/or primary source papers. All students will be expected to read this material. In addition, a broader range of reading sources will be recommended to allow students to read more widely and explore topics of interest in more detail. All reading material will be made readily available either electronically via Blackboard or library on-line resources or in books held on reserve in the library.
