Description and contextualization of the subject

Topics covered will include the description of the normal and pathological histology of marine invertebrates and fish, with special emphasis on the effects of chemical pollutants and other sources of environmental stress.

Aims

¿ To describe the normal and pathological histology of marine animal species: mainly fishes, molluscs and crustaceans.

¿ To Identify histopathological alterations of viral, bacterial, parasitic and toxic (due to pollutant exposure) ethiology

¿ To characterise the cellular and molecular mechanisms involved in pathological damage and organismal defence.



Objectives

At the end of the unit, you should:

1. be familiar with the form and function of organs and tissues in aquatic animals (comparative histology)

2. understand the normal histological organisation of target tissues in molluscs (integument, kidney, blood, digestive gland)

3. understand the normal histological organisation of target tissues in marine fishes (integument, kidney, spleen, blood, liver)

4. recognise major parasites and pathological lesions in molluscs and fish

5. know the value of histopathology in ecosystem health monitoring and marine pollution assessment



Key Skills Acquired

At the end of the unit, you should be able to:

1. conduct histological processing of marine animal tissues

2. identify normal tissues and cell types at the light microscope in marine molluscs and fish

3. identify major parasites and histopathological lesions in marine molluscs and fish

4. search in the web and literature the relevant information concerning molluscs and fish disease, with emphasis in environmentally relevant syndromes
