Overall aims and purpose
The module aims to provide a broad overview of fisheries and detailed training in the techniques used in the assessment of finfish population dynamics. The specific aims are:
1) To develop knowledge and understanding of the anatomy, morphology and ecology of pelagic and demersal finfish.
2) To develop dissection and data collection skills for finfish.
3) To develop knowledge and understanding of the current status of global fisheries
4) To develop knowledge and understanding of techniques used to assess population dynamics of finfish.
5) To understand how these data are used to inform fisheries management.
The course will provide (a) a broad overview of fisheries biology and (b) detailed training in the techniques used in the assessment of finfish population dynamics. In a series of fisheries lectures the following topics will be covered: the current status of global marine finfish fisheries will be discussed; bivalve, gastropod/echinoderm, cephalopod, crustacean and finfish fisheries will be reviewed; the types of models used in stock assessment and fisheries modelling will be introduced; the role of mapping essential fish habitat for commercial species as a means to both target these species during fishing activities and to providing protected areas will be reviewed; the effects of fishing activities on benthos will be discussed. Students will write a short essay (5 credits), selected from a list provided by staff, on a topic that has been covered in the lecture series but also requires further self-study by the student. In a series of fish ecology lectures, students will be introduced to the lifecycles of marine fishes and given a detailed review of how to assess the population dynamics of finfish species: areas to be included are how to estimate abundance, how to age finfish and how to calculate growth rates, mortality rates and maturity ogives. The importance of all of these measurements in developing management models for exploited fish species will be discussed. As part of this course, there will be three laboratory practicals where fish caught on fishing trips in the Field skills module will be dissected and aged. Students will learn about the morphology and ecology of pelagic and demersal fishes, learn dissecting skills and be trained in collection of data that can be used to assess the population dynamics of fishes. The knowledge obtained from these lectures and practicals, together with the student's own self-study will be used to compile a detailed report (15 credits) on the population dynamics of one of the main teleost fish species in the coastal waters of North Wales (e.g. dab, plaice, gurnards, whiting) for the module assessment.
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.The “info-sheet” will be poorly designed (e.g. too many words, use of jargon, lack of photos and infographics) and will not convey information in a clear and concise fashion making it difficult for the reader to easily and quickly understand the topic. The fact sheet will not be of a good enough standard to be published and used for public education by agencies such as Wildlife Trusts or other Conservation NGOS, Cefas or Fisheries authorities.
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. The “info-sheet” will be adequately designed but not presenting the information in an optimal format.to convey information in a clear and concise fashion. The fact sheet will not be of a good enough standard to be published and used for public education by agencies such as Wildlife Trusts or other Conservation NGOS, Cefas or Fisheries authorities but would be so after further modification/editing.
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.The “info-sheet” will clearly and concisely convey a comprehensive summary of a fisheries topic and should be of a standard that would be good enough to be published and used for public education by agencies such as Wildlife Trusts or other Conservation NGOS, Cefas or Fisheries authorities.
On completion of the module students will be able to demonstrate:
Knowledge of the different fisheries resources, exploited by man and their current status.
Ability of handle and analyse data, collate information from various published sources and to communicate this information in the format of an essay or an interpretive report.
Knowledge of the anatomy and morphology of pelagic and demersal finfish and how this relates to the ecology of the species.
Key dissection and laboratory skills to collect accurate data on size, sex, maturity status, and age of finfish species
Understanding and knowledge of the population dynamics of finfish species.

Teaching and Learning Strategy
|Practical classes and workshops||
4 x 7 hrs (2 dissection practicals, 1 ageing practical, 1 data analysis computer practical)
Reading list and web sites will be provided on the module page on Blackboard, to guide students for self-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
