Frozen mackerel, or similar sized (such as herring or pike), fish 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 fish heads are a natural by-product of the food industry. All our frozen specimens are supplied vacuum sealed. Upon receipt specimen will have defrosted, they can then be re-frozen 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 fish 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.

Frozen salmon heads, preserved whole fish and frozen whole fish also available.

Northern Ireland

Sadly, due to the UK leaving the EU, we can no longer supply Northern Irish customers with any products the have codes starting with an 'L' or 'P'. This is due to the requirement for all live or preserved products to have an import licence specific to the customer purchasing and the product being purchased. As each licence takes 2 weeks to obtain, and involves a considerable amount of paperwork, we have made the difficult decision to stop offering these products to Northern Irish customers. We can still offer equipment, i.e. products with an 'E' code, as these simply require customs documentation.

We apologise for the inconvenience and if the legislation changes we will review our decision.

British Islands

Delivery charges to the Isle of Man, Channel Islands (including Jersey & Guernsey), Shetland, Orkney and all the other islands we've missed, are the same as to mainland Britain (see above). The main difference is that delivery is likely to take a little longer, and for this reason we cannot guarantee next day delivery.

In addition, we cannot ship any liquids, so any 'wet' specimen ordered will be sent vacuum packed rather than in a jar.

International Orders

We welcome international orders but please note only non-perishable and non-animal derivative items, i.e. only those with codes starting with an 'E', can be sent.

Buyer is responsible for all import duties and taxes. EU businesses need to supply an EORI number before we can ship.

EU Delivery: £28

If you wish to buy something very small/lightweight, or need urgent delivery, please contact us for a postage quote, otherwise standard charges apply.
