  1. Sea- Saltwater fishes Flat fish / Round fish Freshwater fishes Migratory fishes Fish Source: On Cooking, Chapter 20, page 561 to 577

  2. Fish are aquatic animals with fins for swimming and gills for breathing. There are over 30’000 species of which most live in seas and oceans, while freshwater fish are far less numerous. All fish are highly perishable but with improved preservation and transportation techniques they are now readily available fresh or frozen almost anywhere. The general term fish includes both fresh and saltwater varieties. They have fins and an internal skeleton of bone and cartilage Fish

  3. Sea fish - Saltwater fish • Round fish • Flat fish • Migratory fish • Fish that migrate either fresh water to saltwater and back for spawning or vice versa or migrate between sea or freshwater without spawning • Fresh water fish • Round fish only • Lake fish and river fish Classification of Fish

  4. Diminishing fish in the world seas has led to an increased establishment of aquafarming both for seawater and freshwater fish. Fresh water fish are farmed in ponds, for river fish varieties often with added flow of water to simulate the stream of water in a river. Aerating is necessary to ensure the natural amount of CO2 in the water. Saltwater fish is farmed off the coast in large netted enclosures. Artificial feeding is very important to the final product of the fish, as the fish can’t naturally “hunt” it’s prey. Aquafarming

  5. Based on the shape and skeletal structure, fish are divided into two major categories • Round Fish • Swim in vertical position • Eyes on both sides of the heads • Shape might be round, oval or compressed • Flat fish • Swim in horizontal position • Eyes on top of their head • Bottom dwellers with dark skin on top and light skin underneath for camouflage • Some change colors according to surroundings • Small scales and dorsal and anal fins run the full length of the body Fish – Structure and Mussel composition

  6. This is a difficult task due to the vast number of species and at times very similar appearance. Adding to the confusion is the fact that the same fish may have different names in different locations and some species are referred to by their foreign name even on menus of restaurants. The FDA has a list of approved market names for the US which helps but is not used in common jargon a good referral guide. Fish - identification

  7. Bass Several fresh and seawater species which are spiny-finned. The freshwater varieties are members of the unrelated sunfish family. They’re meat is lean and delicate. • Largemouth / smallmouth / redeye and black bass The saltwater varieties are very popular and commercially often used: • Black sea bass / Striped bass Sea fish - Round fish

  50. Mollusks are mainly sea creatures although there are some found in fresh water and some on land (land snail) There are generally three categories of mollusks: Univalves Single shell with soft bodies. Mainly marine snails with one foot used to attach them selves to a fix object (eg rocks) Bivalves Mollusks with two shells that are attached to each other by a “hinge” Cephalopods Marine mollusks with distinct heads and developed eyes and several arms attached to the head near the mouth No outer shell but a small inner shell called pen or cuttlebone mollusks
