1. CHAPTER 14FISH AND SHELLFISH Gilbert Noussitou 2010

2. Fish and Shellfish • Fish are aquatic vertebrates with fins for swimming and gills for breathing • More than 30,000 known species • Most species live in our seas and oceans • Freshwater species are less numerous • Shellfish are aquatic invertebrates with shells or carapaces • Found in fresh and salt water Gilbert Noussitou 2010

3. Fish and Shellfish • Due to increased demand, improved preservation, and transportation techniques, good quality fish and shellfish are readily available • Many fish and shellfish are expensive • All are highly perishable • Cooking times are generally short • Taste is generally mild and delicate • Special attention must be given to prevent spoilage and retain quality Gilbert Noussitou 2010

4. Structure and Muscle Composition • Fish includes fresh and saltwater varieties • Fish has skin and an internal skeleton of bone and cartilage • Fish can be classified into two groups: • Round fish • Flat fish • In cooking, fish is also classified into 2 categories • Lean • Fat Gilbert Noussitou 2010

5. Classification • The fish and shellfish used in the foodservice industry can be divided into 3 categories: • Fish: • Mollusks • Crustaceans Gilbert Noussitou 2010

29. Fish and Shellfish • Nutrition • Low in calories, fat and sodium • High in protein and vitamins A, B and D • Fish are high in a group of polyunsaturated fatty acids called Omega-3 • Inspections and Grading • C.F.I.A. is the only approval granting agency under federal regulations • Approved facilities must adhere to a HACCP program • No grading protocol exists in Canada. Buying must rely on the integrity of the supplier Gilbert Noussitou 2010

30. Inspection • C.F.I.A. mark and statement Gilbert Noussitou 2010

31. Freshness • Fish and shellfish are highly perishable • Fish and shellfish must be kept cold at all times • Checking Freshness: • Smell – Eyes • Gills – Fins • Texture – Scales • Appearance – Movement Gilbert Noussitou 2010

35. Storage • Most important concern with storage is temperature • All fresh fish should be stored at; -1 to +1°C (30 to 34°F) • Store on ice • Store bivalves in shipping packages at 4°C (40°F) in high-humidity environment • Can keep crustaceans in salt-water tanks Gilbert Noussitou 2010

36. Applying Various Cooking Methods • Dry heat • Broiling and grilling, baking, sautéing, pan-frying • Moist heat • Steaming: • “en papillote” • Poaching: • “deep poaching” (court-bouillon) • “shallow poaching” (white wine, fumet etc.) • Simmering Gilbert Noussitou 2010
