Lesson Content/Board Summary

Materials and methods of harvesting fish

Types of Fishing Gears

Fishing gears are equipment used to catch fish and other aquatic animals. The choice of gear depends on the target species, water body, and fishing method.

1. Traps

Traps are passive fishing gears designed to capture fish by enticing them into an enclosure from which escape is difficult. They are often baited and left in the water for some time.

1. Basket traps: Made from woven materials like bamboo or raffia, used in rivers and shallow waters.
2. Pot traps: Made from wire mesh or plastic, commonly used for crabs, lobsters, and some fish species.
3. Fyke nets: Long, cylindrical nets with funnel-shaped entrances, often set in shallow waters.

2. Hooks and Line

This is a simple and widely used method involving a hook attached to a line, often with bait, to catch individual fish.

1. Handline: A single line held by hand.
2. Rod and reel: A fishing rod with a reel to manage the line.
3. Longline: A main line with many baited hooks attached at intervals, used for catching large quantities of fish.

3. Cast Nets

A cast net is a circular net with weights distributed around its edge. It is thrown by hand in such a way that it spreads out and sinks, trapping fish underneath as it is retrieved.

1. It is effective in shallow waters and for catching schooling fish.

4. Gill Nets

Gill nets are walls of netting set in the water, designed to entangle fish by their gills as they try to swim through. The mesh size is crucial, as it determines the size of fish caught.

1. They can be set vertically in the water column, either floating or anchored.
2. Commonly used for catching species like tilapia, catfish, and sardine.

5. Drag Nets (Seines)

Drag nets are long nets with floats on the top and weights on the bottom, used to encircle and capture fish by dragging them towards the shore or a boat.

1. Beach seines: Operated from the shore, encircling fish in shallow coastal waters.
2. Purse seines: Large nets used to encircle schools of fish in open water, with a drawstring at the bottom to close the net like a purse.

6. Scoop Nets

Scoop nets are small, hand-held nets with a handle, used for scooping up fish from shallow waters, ponds, or tanks. They are often used for harvesting fish in aquaculture or for small-scale fishing.

1. They are simple to operate and suitable for catching small fish or transferring fish.

7. Traw Nets (Trawls)

Traw nets are large, cone-shaped nets that are towed through the water by one or more boats (trawlers) to catch fish. They are effective for catching demersal (bottom-dwelling) and pelagic (mid-water) fish.

1. Bottom trawls: Dragged along the seabed to catch groundfish.
2. Mid-water trawls: Towed in the mid-water column for pelagic species.

Teaching Methods/Instructional Techniques

Discussion, Demonstration, Guided Practice, Question and Answer, Explanation, Observation, Practical Activity.

Instructional Procedures

Step 1: Introduction

Time: 5 minutes

Teaching Skill: Engagement/Questioning

Teacher’s Activity: The teacher greets the students and asks them if they have ever seen anyone catch fish, or if they know how fish are caught. The teacher then introduces the topic: “Materials and methods of harvesting fish.”

Pupils’ Activity: Students respond to the questions and listen attentively to the introduction.

Learning Point: Introduction to fish harvesting

Step 2: Presentation of Fishing Gears (Traps and Hooks & Line)

Time: 8 minutes

Teaching Skill: Demonstration/Explanation

Teacher’s Activity: The teacher presents actual samples or clear images of different types of traps (e.g., basket trap, pot trap) and hooks with fishing lines. The teacher explains what each gear is and how it is used to catch fish, focusing on traps and hooks/line.

Pupils’ Activity: Students observe the materials, listen to the explanations, and ask questions for clarification.

Learning Point: Traps and hooks identification

Step 3: Discussion of Cast Nets and Gill Nets

Time: 7 minutes

Teaching Skill: Explanation/Discussion

Teacher’s Activity: The teacher presents samples or diagrams of cast nets and gill nets. The teacher explains their characteristics, how they are deployed, and the types of fish they are typically used to catch. The teacher encourages students to share any experiences or knowledge about these nets.

Pupils’ Activity: Students observe the nets, participate in the discussion, and contribute their ideas.

Learning Point: Cast and gill nets understanding

Step 4: Exploring Drag Nets and Scoop Nets

Time: 7 minutes

Teaching Skill: Visualisation/Description

Teacher’s Activity: The teacher uses charts or pictures to illustrate drag nets (seines) and scoop nets. The teacher describes their structure, method of operation (e.g., dragging towards shore for seines, scooping for scoop nets), and their applications in different fishing environments.

Pupils’ Activity: Students view the illustrations, listen to the descriptions, and identify key features of each net type.

Learning Point: Drag and scoop nets features

Step 5: Understanding Traw Nets

Time: 6 minutes

Teaching Skill: Explanation/Comparison

Teacher’s Activity: The teacher explains traw nets, describing them as large, cone-shaped nets towed by boats. The teacher differentiates between bottom trawls and mid-water trawls and discusses their impact on marine ecosystems (briefly, if time permits).

Pupils’ Activity: Students listen to the explanation and understand the concept of trawling and its variations.

Learning Point: Traw nets characteristics

Step 6: Practical Application/Reinforcement

Time: 3 minutes

Teaching Skill: Practical demonstration/Reinforcement

Teacher’s Activity: If practical materials are available, the teacher briefly demonstrates how a simple hook and line is set up, or how a small trap might be baited. The teacher reinforces the importance of choosing the right gear for the right purpose.

Pupils’ Activity: Students observe the practical demonstration and ask final questions about the gears.

Learning Point: Gear application reinforcement

Step 7: Evaluation/Review

Teacher Guide for Using This Lesson Plan

Before the lesson, ensure you have actual samples of fishing gears or clear, large visual aids (charts, pictures, or videos) ready for presentation. Arrange the materials in an organised manner for easy demonstration. During the lesson, encourage active participation and allow students to handle safe fishing gear samples under supervision. Emphasise the practical aspects of each gear. Guide students to copy the Board Summary notes during Step 8. Check for understanding throughout the lesson by asking questions and clarifying misconceptions. For weaker learners, provide extra visual cues and repeat explanations. For faster learners, encourage deeper inquiry into the mechanics or ecological implications of the gears. Remind students about safety when discussing or handling any sharp objects like hooks.
