Lesson Content
A. Introduction (Building Background Knowledge)
- The teacher revises the previous lesson on poultry cookery, covering topics such as poultry types, nutritional value, factors for choosing poultry, preparation, and cooking methods.
- The teacher asks students:
- Have you eaten fish or seafood before?
- What are some examples of fish you know?
- How do people cook fish in your community?
- The teacher then introduces the new topic by explaining that seafood includes all edible aquatic animals and plants, including fish and shellfish.
B. Lesson Explanation (Content Development)
1. Definition of Seafood Cookery
Seafood cookery refers to the preparation and cooking of edible aquatic animals, including fish and shellfish, in various ways to enhance flavor, texture, and nutritional benefits.
2. Broad Division of Seafood
A. Fin Fish (Fish with Fins and Backbones)
Fin fish are fish with fins on their bodies and are divided into:
-
White or Lean Fish – These have their fat stored in the liver rather than between the muscle fibers. Their flesh is white, and examples include:
- Cod
- Halibut
- Tilapia
- Bream
-
Oily or Fat Fish – These have fat distributed throughout their body, giving them darker flesh. Examples include:
- Herrings
- Mackerel
- Salmon
B. Shellfish (Aquatic Animals with Protective Shells)
Shellfish are further divided into:
-
Soft-bodied Shellfish (Mollusks) – These have soft bodies protected by shells. Examples include:
- Oysters
- Clams
- Scallops
- Mussels
-
Crustaceans – These have segmented crust-like shells. Examples include:
- Lobsters
- Shrimps
- Crabs
- Crayfish
3. Nutritive Value of Seafood
Seafood provides essential nutrients, including:
- Protein – High-quality, complete protein with essential amino acids.
- Fat – Oily fish provide healthy fats, including omega-3 fatty acids.
- Minerals –
- Calcium (from small fish eaten with bones)
- Iron (especially in oysters)
- Iodine (found in sea fish due to seawater content)
- Vitamins –
- B-complex vitamins
- Vitamins A and D in fatty fish
- Low Carbohydrate Content – Fish contains little to no carbohydrates and should be paired with carbohydrate-rich foods.
4. Fish Cuts and Market Forms
Fish are sold in different cuts, including:
- Whole or Round Fish – Sold as caught from the water.
- Drawn Fish – Internal organs removed.
- Dressed Fish – Scales, head, tail, and fins removed.
- Steaks – Cross-section slices from large dressed fish.
- Fillets – Boneless fish sections cut lengthwise from the backbone.
5. Methods of Cooking Seafood
Seafood can be cooked using various methods to retain flavor and nutrients:
- Frying – Cooking fish in hot oil (e.g., deep frying or shallow frying).
- Boiling – Cooking in hot water with seasonings.
- Stewing – Slow cooking in a small amount of liquid.
- Steaming – Cooking using steam to retain nutrients.
- Grilling – Cooking over an open flame or under a grill.
- Baking – Cooking in an oven at controlled temperatures.
C. Class Activity
- Teacher shows pictures of various types of seafood.
- Students classify different fish into fin fish and shellfish based on characteristics.
- Teacher demonstrates how different fish cuts look using pictures or real samples.
- Students discuss preferred seafood cooking methods in their culture.
