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 sell mackerel heads by the kilo, there are around 10-18 heads per kilogram depending on size. We also offer a 25% discount if 3 packs are purchased, they will be vacuum packed in 1kg bags so can be defrosted and used as needed.
Preserved whole fish, preserved fish heads and frozen whole fish also available.
