Show Answer
1. Answers may include: hand line fishing, spearfishing, net casting, fish trapping.
2. Examples: scoop net, hooks and lines, cast nets, fish cages.
3. Because each environment requires specific tools - e.g., scoop nets for shallow water, cast nets for schools of fish, and stationary traps for rivers or coastal areas.
📖 Explore the Lesson (Day 2: Fishing Gears Used for Catching Fish)
Fishing has been a vital human activity for thousands of years. From simple sticks and strings to modern nets and machines, fishing gears have evolved to make catching fish more efficient and sustainable. Just like in farming on land where we use plows, shovels, and tractors, in aquaculture and fisheries, fishermen use different fishing gears depending on the type of fish, water environment, and purpose.
Let’s explore the most common fishing gears used in aquaculture and fisheries, and why each of them is important.
1. Scoop Net 🥅
A scoop net is a handheld tool with a frame and mesh used to catch fish or other aquatic organisms.
- Where it’s used: In rivers, ponds, or shallow areas where fish are easy to reach.
- Why it matters: It allows fishermen to catch fish carefully without harming them, often used in scientific research or small-scale fishing.
Student example: Imagine using a butterfly net, but instead of catching butterflies, you use it to scoop fish from a pond.
2. Seine Net 🌊
A seine net is a large fishing net with weights at the bottom and floats at the top. It is dragged through water to trap fish.
- Where it’s used: In lakes, ponds, and coastal areas.
- Why it matters: It can catch a large number of fish at once, making it efficient for commercial fishing.
Student example: Picture a giant curtain being pulled through water, sweeping fish into a “pocket” at the center.
3. Cast Net 🎣
A cast net is a circular net with small weights around its edge. Fishermen throw it over schools of fish, and the weights sink the net to trap them.
- Where it’s used: Shallow waters, rivers, and near shorelines.
- Why it matters: It is low-cost, effective, and commonly used in traditional fishing communities.
Student example: Think of throwing a blanket with small stones around the edges. As it lands, it covers and traps the fish.
4. Hand Diggers and Collectors ✋
These are simple tools like small shovels, rakes, or hands used to collect aquatic organisms from the water or substrate.
- Where it’s used: In shellfish gathering (like clams, mussels, or oysters).
- Why it matters: They allow sustainable harvesting of small aquatic organisms.
Student example: Like digging in the sand for seashells, but in aquaculture, you’re digging for edible shellfish.
5. Dredges ⚙️
Dredges are heavy mechanical devices dragged along the bottom of lakes, rivers, or seas to collect shellfish or remove unwanted materials.
- Where it’s used: In deeper water environments, often for clams or oysters.
- Why it matters: They can harvest large amounts at once, but if not managed well, can disturb the ecosystem.
Student example: It’s like using a giant underwater vacuum to scoop things from the seafloor.
6. Spears 🪙
Spears are pointed tools used to catch fish by piercing or impaling them. Spearfishing is one of the oldest fishing methods.
- Where it’s used: Shallow waters, reefs, and rivers.
- Why it matters: It requires skill, patience, and direct targeting of fish, making it a selective method that avoids bycatch.
Student example: Like playing darts, but underwater, aiming at moving fish.
7. Stupefying Aids 💨
These are substances used to temporarily stun fish, making them easier to catch. However, their use is highly regulated because they can harm ecosystems if abused.
- Where it’s used: Traditionally in some communities, but not encouraged today.
- Why it matters: Shows how fishing methods have evolved - modern sustainable practices avoid these aids.
8. Hooks and Lines 🪝
Also called angling gear, hooks and lines are among the most traditional fishing tools. A baited hook is attached to a line to catch individual fish.
- Where it’s used: Rivers, lakes, seas - widely used worldwide.
- Why it matters: Still one of the most popular methods for both food fishing and recreation.
Student example: Think of going fishing with a simple rod and line.
9. Stationary Entangling Nets 🧵
These nets are fixed in one place, waiting for fish to swim into them. As fish pass, they get entangled in the mesh.
- Where it’s used: Rivers, lakes, and coastal areas.
- Why it matters: They are passive gears that can catch fish without constant human effort.
10. Stationary Enclosures 🏠
Also known as fish traps or weirs, these are structures built in water to guide fish into an enclosure from which they cannot escape.
- Where it’s used: Shallow rivers or tidal areas.
- Why it matters: A traditional but effective method, allowing selective capture of fish.
Student example: Imagine building a fence in water that guides fish into a cage.
11. Mobile Enclosing Nets 🔒
Also called purse seines, these are huge nets used to encircle schools of fish in open water. Once closed at the bottom like a purse, the fish are trapped inside.
- Where it’s used: Open seas and large lakes.
- Why it matters: A modern method that catches large quantities but must be used responsibly to avoid overfishing.
Why Different Fishing Gears? ⚖️
Different fishing gears are used because:
- Some fish live near the surface, others at the bottom.
- Some gears are for small-scale fishing, others for commercial operations.
- Some are selective (catching only target fish), while others risk catching non-target species (bycatch).
Safety & Sustainability 🌍
Using fishing gears responsibly is very important:
- Overfishing with large nets can harm fish populations.
- Destructive gears like some dredges or stupefying aids can damage habitats.
- Sustainable fishing practices ensure there will be fish for future generations.
