Instructional Materials

The teacher will teach this lesson with the aid of:

Pictures of industrial fishing trawlers
Video clips showing fish processing vessels
Diagrams of large fishing nets (e.g., purse seine, trawl net)
Images of cold storage facilities

Rationale for the Lesson

This lesson helps pupils understand the large-scale commercial aspect of fisheries, which is a major part of the food industry and economy. It enables them to differentiate between small-scale and large-scale fishing methods and their impact.

Prerequisite/Previous Knowledge

Pupils have some basic knowledge of fishing as a source of food and livelihood, and they may have heard of different ways fish are caught.

Lesson Content/Board Summary

Sub-division of Fisheries: Industrial Fisheries

Meaning of Industrial Fisheries

Industrial fisheries refer to large-scale fishing operations conducted with significant capital investment, advanced technology, and large vessels. The primary aim is commercial profit, often supplying fish to processing plants, canneries, or for export.

Types of Industrial Fisheries

The following are common types of industrial fisheries based on the gear and methods used:

Trawling: Involves dragging a large net (trawl) through the water or along the seabed to catch fish. There are bottom trawling and mid-water trawling.
Purse Seining: Uses a large net to encircle a school of fish, and then the bottom of the net is drawn together like a purse to trap the fish. Commonly used for tuna, sardines, and mackerel.
Longlining: Employs a very long line with many baited hooks attached at intervals. It can extend for many kilometers and targets fish like tuna, swordfish, and halibut.
Drift Netting: Uses long nets that drift freely in the open ocean. While effective, large-scale drift netting is often regulated or banned due to bycatch issues.
Dredging: Involves dragging a dredge (a metal frame with a net bag) along the seabed to collect shellfish like oysters, clams, and scallops.

Examples of Industrial Fishing Operations

The following are examples of industrial fishing operations:

Large trawlers operating in the Atlantic Ocean to catch vast quantities of cod, hake, or pollock, which are then processed and frozen on board.
Purse seine vessels targeting large schools of tuna in the Pacific Ocean, with the catch often destined for canning factories.
Longline fleets deploying thousands of hooks across vast ocean stretches to catch high-value species like swordfish and bluefin tuna.
Factory ships that not only catch fish but also process, fillet, freeze, and package them at sea.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and asks them to mention different ways people catch fish (e.g., hook and line, net). The teacher then steers the discussion towards large-scale fishing methods.
Pupils’ Activity: Pupils respond by mentioning various fishing methods they know.
Learning Point: Pupils recall prior knowledge about fishing and are prepared for the lesson.

Step 2: Presentation of Meaning of Industrial Fisheries

Time: 10 minutes
Teaching Skill: Explanation/Definition
Teacher’s Activity: The teacher explains the meaning of industrial fisheries, highlighting its characteristics such as large scale, use of technology, and commercial objectives. The teacher may show pictures of large fishing vessels.
Pupils’ Activity: Pupils listen attentively, observe the pictures, and ask questions for clarification.
Learning Point: Pupils understand the definition and key features of industrial fisheries.

Step 3: Discussion of Types of Industrial Fisheries

Time: 10 minutes
Teaching Skill: Elaboration/Categorization
Teacher’s Activity: The teacher introduces and explains different types of industrial fisheries, such as trawling, purse seining, longlining, drift netting, and dredging. The teacher uses diagrams or video clips to illustrate each type.
Pupils’ Activity: Pupils listen, observe the visual aids, and take notes. They may contribute by describing what they see.
Learning Point: Pupils learn about the various methods and gear used in industrial fishing.

Step 4: Examples of Industrial Fishing Operations

Time: 7 minutes
Teaching Skill: Illustration/Application
Teacher’s Activity: The teacher provides concrete examples of how industrial fishing operations are carried out, linking them to the types previously discussed. The teacher emphasizes the scale and purpose of these operations.
Pupils’ Activity: Pupils listen to the examples and relate them to the types of fisheries. They may share any examples they know.
Learning Point: Pupils understand practical applications and real-world scenarios of industrial fisheries.

Step 5: Lesson Summary and Key Points

Time: 3 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher quickly summarizes the main points of the lesson, reiterating the definition, types, and examples of industrial fisheries.
Pupils’ Activity: Pupils listen and review their notes.
Learning Point: Pupils reinforce their understanding of the lesson content.

Step 6: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define industrial fisheries.
Mention three types of industrial fisheries.
Give two examples of industrial fishing operations.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 7: Conclusion

Time: 5 minutes
Teaching Skill: Consolidation
Teacher’s Activity: The teacher commends the pupils for their participation and provides homework: “Research the environmental impact of industrial fisheries and be prepared to discuss it in the next class.”
Pupils’ Activity: Pupils note down the assignment and prepare for the next lesson.
Learning Point: Pupils are encouraged to explore the topic further and connect it to broader issues.

Lesson Keywords

Industrial Fisheries – Large-scale fishing operations for commercial profit.
Trawling – Fishing method using a large net dragged through water or along the seabed.
Purse Seining – Method using a net to encircle a school of fish, then drawn together at the bottom.
Longlining – Fishing method using a very long line with many baited hooks.
Dredging – Method using a dredge to collect shellfish from the seabed.

Differentiation

For pupils who grasp concepts quickly, the teacher can encourage them to research specific industrial fishing vessels or processing techniques. For those who need more support, the teacher can provide simplified diagrams and allow for peer support during activities.

Note for teachers using this lesson plan

Ensure to use clear and relevant visual aids, such as pictures or short video clips, to help pupils visualize the large-scale nature and complexity of industrial fisheries. Emphasize the economic importance while briefly touching on potential environmental considerations to spark further interest.
