Frozen mackerel heads, ideal for affordable A-level biology dissection practicals. Gills and operculum present.
Most specimens have the pectoral fins present, although there is variation - please see image 4 for examples of variance.
All fish are sustainably sourced in the UK.
Our mackerel heads are processed and prepared in the same way as food produced for human consumption; they are a natural by-product of the food industry. They are then vacuum sealed and frozen. Upon receipt specimen is likely to have defrosted, either re-freeze for dissection at a later date (use within 2 years) or kept refrigerated if required imminently (within 2 days). Not suitable for human consumption.
We offer a pack of 10 or a great value class pack of 30 heads.
