VRQ2 Theory Unit 711 UPK 711

2. Classification Fish can be classified into 3 types; Round Oily Flat
and 2 groups;
Fresh water
Saltwater
There are some fish that live in both fresh and saltwater and these are called Estuarine fish.

3. The main way to define a round fish is that it has eyes on either side of its body
Some fish which may seem flat are actually compressed vertically (John Dory)
Flat fish have eyes on one side of their body only

4. External Anatomy of Round Fish

5. White and Oily Fish All fish contain oil to some degree
Depending on where the fish live and their lifestyle will determine their fat content, also seasonal
Active fish and those from cold waters will have higher fat levels
White fish can be considered sprinters, and oily fish marathon runners

9. Cookery Methods of Fish
Unlike animal muscle fibres which are long, fish muscle tissue is short separated by connective membranes
This connective tissue is easily gelatinised by heat, resulting in the flaking effect of cooked fish

10. Cookery Methods of Fish
This also results in cooked fish being moist and succulent and dried out tough fish if overcooked.
Oily fish when cooked, release their fats (mainly under the skin) to help keep the cooked flesh moist.
Because fish flesh is fine and delicate, fast cooking or gentle moist cooking are the best methods.

11. Methods of Cookery Deep Frying Grilling Baking Steaming Poaching
Shallow frying

12. Fish Farming
Advances in technology and fish husbandry have improved aquaculture
Only fish that do not have a planktonic stage (most Fresh water) can be easily grown
Seawater fish have a planktonic stage, so are more difficult, but some advances have been made
Fish can be wild caught as youngsters and then grown on in sea pens

13. Advantages / Disadvantages of fish farming
Sustainable
Available year round
Guaranteed size
Cheaper
Need to feed fish protein, so need catches of other fish to make feed
Pollution
Contamination
Less intense flavour and texture than wild
