Activity 14 - Report on freshwater fish in Scotland
Background for teachers
The vendace is one of the UK’s rarest freshwater fish. It has only ever been known from four locations in the UK, two in Scotland and two in England. It became extinct in Scotland by 1970 and was reintroduced to two Scottish sites in the late 1990s. One of these introductions, to Loch Skene, has proved successful. The vendace has recently disappeared from one of its English locations and so is now known only from one site in England and Loch Skene.
Genetics and Adaptation
Selection and speciation: conservation of species through wildlife reserves
Biology Advanced Higher
Interactions in ecosystems: competition
Managing Environmental Resources Higher
Investigating Ecosystems: human activities – their effect on ecosystems and strategies for improvement.
Curriculum for Excellence
This activity will help pupils achieve the four capacities of learning by:
- encouraging enthusiasm and motivation for learning;
- encouraging openness to new thinking and ideas;
- use of literacy and numeracy skills;
- use of technology for learning;
- thinking creatively and independently;
- making reasoned evaluations;
- evaluating environmental issues;
- applying critical thinking in new contexts, and
- creating and developing.
16-18 years [Language level of most resources is probably too high for the majority of younger pupils.]
Ask pupils to write a scientific report on freshwater fish in Scotland. In their report they should:
- use the piechart and relevant text in SNH Natural Heritage Trends: Freshwater Fish to describe trends in native freshwater fish populations in Scotland;
- highlight the problems of exotic fish and North American signal crayfish; and
- write a case study of the vendace, the rarest of UK freshwater fish, threats to the species including non-native species, and the reintroduction of the vendace to Scotland.
Pupils can find the information they need from the sources below.
