ICT in the Fishing Industry

Information and Communication Technology (ICT) helps fishers identify areas where fish are concentrated and plan fishing activities. By collecting and analysing information from the sea, ICT can help fishing crews decide where and when to fish.

The process shown in this note uses sensors, data analysis, internet communication, and devices on fishing trawlers. These technologies can help improve catch rates, reduce unnecessary travel, save fuel and time, and support more effective fishing.

How ICT Is Used in the Fishing Industry

ICT can support fishing by collecting information about sea conditions, analysing the collected data, and communicating useful information to fishing vessels.

The process includes four main stages:

1. Data collection: Sensors placed in the sea collect information about the surrounding water.
2. Data analysis: Collected data is analysed to identify areas where fish may be concentrated.
3. Data transmission: The analysed information is sent to a server through the internet.
4. Information transfer to fishing trawlers: Fishing crews receive the information on their devices and can use it to plan where to fish.

Sensors

A sensor is a device that detects or measures a physical condition and produces data that can be recorded or processed.

In the fishing industry, sensors can be placed in the sea to collect information about water and environmental conditions. The note identifies several types of data that may be collected:

• Water temperature: Measures how warm or cold the water is.
• Salinity: Measures the amount of dissolved salts in the water.
• Depth: Measures the depth of the water at a particular location.
• Currents: Provides information about the movement of seawater.
• Chlorophyll level: Measures chlorophyll in the water, which can be useful when studying marine conditions.
• Oxygen level: Measures the amount of dissolved oxygen in the water.

These measurements provide information about the marine environment. The information can be used as input for further analysis to help identify possible fishing areas.

A sensor placed in the sea measures water temperature, depth, and other conditions. The measurements are collected as data and sent for analysis. The resulting information can help fishing crews understand the conditions in different areas.

Fish Concentration Analysis

Fish concentration refers to an area where a relatively large number of fish are gathered. Finding such areas can help fishers plan their activities.

Sensor data can be analysed to identify locations that may have suitable conditions for fish or where fish are likely to be concentrated. The analysis may be displayed visually on a screen, such as a map or a colour-coded image.

The note illustrates how a display can show areas with different levels of possible fish concentration. A high-concentration area can be highlighted so that fishers can identify it more easily.

The analysis provides information to support decisions; it does not guarantee that fish will be present at the indicated location. Actual conditions can change, and fishers may need to use other observations and equipment as well.

After analysing collected data, a system displays a possible high-concentration area on a screen. A fishing crew can use this information when deciding which location to visit.

Internet and Data Transmission

After the collected data has been analysed, the information can be sent to a server through the internet.

A server is a computer system that provides services or information to other devices. In this process, the server can receive and make the analysed fishing information available to fishing crews.

The internet enables information to be communicated between the system that processes the data and devices used by fishing vessels. The availability of this communication depends on the network connection and equipment in use.

Role of the Internet

• Transfers analysed information to a server.
• Makes information available to connected devices.
• Helps communicate useful fishing information to trawlers while they are at sea, where a suitable connection is available.

Information Transferred to Fishing Trawlers

A fishing trawler is a fishing vessel used to catch fish. In the process shown in the note, fishing trawlers receive analysed information through communication technology.

The information can be displayed on devices aboard the vessel. The crew can use it to identify possible fishing locations and plan their route.

When fishers have useful information before travelling to a fishing area, they may be able to avoid spending unnecessary time searching in less suitable locations.

A fishing crew receives information showing a possible area of high fish concentration. The crew can use the information to plan a route towards that area and decide where to carry out fishing activities.

How the Process Works

The stages in the note are connected. Each stage uses the output of the previous stage.

Benefits of ICT in the Fishing Industry

Finding Fish More Effectively

Analysed information can help fishers identify possible areas where fish are concentrated. This can reduce the time spent searching for suitable fishing locations.

Saving Fuel and Time

When crews can plan routes using information about possible fishing areas, they may avoid unnecessary travel. This can help reduce fuel consumption and save time.

Improving Catch Rates

Information about possible fish concentration areas can help fishers choose where to fish. This may improve the chance of making a catch, although a particular catch cannot be guaranteed.

Reducing Costs

Using time and fuel more efficiently can help reduce some fishing costs. The actual savings depend on the equipment, communication costs, conditions at sea, and how the information is used.

Planning Fishing Trips

Information about sea conditions and possible fishing locations can help crews plan their trips more effectively.

Supporting Sustainable Fishing

ICT can provide useful information for managing fishing activities. However, the use of technology alone does not ensure sustainable fishing; fishing practices and applicable rules also matter.

Important Examination Points

Students should be able to:

1. Identify the types of data that sensors can collect from the sea.
2. Explain how collected data is analysed to identify possible fish concentration areas.
3. Describe the role of the internet and a server in transmitting analysed information.
4. Explain how fishing trawlers use the information they receive.
5. State the benefits of ICT in fishing, including saving fuel and time, reducing costs, and helping improve catch rates.

Practice Questions

1. State four types of information that sensors can collect from the sea.

Possible answers include water temperature, salinity, depth, currents, chlorophyll level, and oxygen level.

2. What is the purpose of analysing the data collected by sea sensors?

The data is analysed to identify possible areas where fish are concentrated.

3. What is the role of the internet in the fishing process shown in the note?

The internet is used to send the analysed information to a server so that it can be made available to fishing trawlers.

4. How do fishing trawlers use the information they receive?

Fishing crews use the information to identify possible fishing locations and plan where to fish.

5. State three benefits of using ICT in the fishing industry.

• Helps fishers find possible fishing areas.
• Saves time and fuel.
• Can improve catch rates and reduce costs.

6. Arrange the stages of the process in the correct order.

Data collection → Data analysis → Data transmission → Information transferred to fishing trawlers → Fishing decisions.

Summary

ICT helps the fishing industry use information to plan fishing activities. Sensors collect sea data, such as temperature, salinity, depth, currents, chlorophyll level, and oxygen level. The data is analysed to identify possible fish concentration areas. The analysed information is then sent to a server through the internet and transferred to fishing trawlers.

Fishing crews can use this information to plan where to fish. This can help them find fish more effectively, save time and fuel, reduce costs, and potentially improve catch rates.
