Fishing has always been a fuel-intensive livelihood. Unlike a lorry that can optimize its route or a factory that can reduce shifts, a fishing boat has to travel to where the fish are and back again. There are no shortcuts across the ocean. With diesel prices at RM3.35 per litre for subsidized users and significantly more on the open market, the economics of fishing in Malaysia are being tested in ways that affect livelihoods directly.

How Much Diesel Does Fishing Actually Require?

Fishing vessel fuel consumption depends on the boat size, engine type, trip distance, and duration. Here is what different types of Malaysian fishing operations typically use:

Coastal fishing (day trips, small boats):

Vessel: 20-40 foot boats with single engines
Fuel per trip: 100-150 litres
Trip frequency: 20-25 trips per month
Monthly fuel: 2,000-3,750 litres

Near-shore trawling (2-3 day trips):

Vessel: 40-60 foot trawlers
Fuel per trip: 300-600 litres
Trip frequency: 8-12 trips per month
Monthly fuel: 2,400-7,200 litres

Deep-sea fishing (5-14 day trips):

Vessel: 60-100+ foot vessels
Fuel per trip: 1,500-5,000 litres
Trip frequency: 2-4 trips per month
Monthly fuel: 3,000-20,000 litres

These numbers make fishing one of the most diesel-dependent industries in Malaysia. Fuel typically represents 30 to 50 percent of total operating costs, and for some deep-sea operations, it can reach 60 percent.

The Cost Impact: Real Numbers

Let us work through three scenarios representing different scales of fishing operation.

Coastal Fisherman

A coastal fisherman running a 30-foot boat, making 20 trips per month, using 120 litres per trip:

Monthly fuel use: 2,400 litres

At RM2.15/litre: RM5,160/month
At RM3.35/litre: RM8,040/month
Monthly increase: RM2,880

For a coastal fisherman whose monthly catch might bring in RM8,000-12,000, an extra RM2,880 in fuel costs is devastating. That money was previously available for engine maintenance, gear replacement, crew wages, and family expenses.

Mid-Size Trawler Operator

A trawler operator running a 50-foot vessel, making 10 trips per month, using 500 litres per trip:

Monthly fuel use: 5,000 litres

At RM2.15/litre: RM10,750/month
At RM3.35/litre: RM16,750/month
Monthly increase: RM6,000

Six thousand ringgit per month is a significant amount. This operator needs to catch and sell substantially more fish just to cover the fuel increase, which is not always possible given fishing ground conditions and seasonal patterns.

Deep-Sea Operator

A deep-sea vessel making 3 trips per month, using 2,500 litres per trip:

Monthly fuel use: 7,500 litres

At RM2.15/litre: RM16,125/month
At RM3.35/litre: RM25,125/month
Monthly increase: RM9,000

At unsubsidized rates of RM5.52 per litre, this vessel would spend RM31,500 per month on diesel - nearly double the old subsidized cost.

The Fishing Subsidy Situation

The Malaysian government has historically provided diesel subsidies to registered fishermen, recognizing both the economic importance of the fishing industry and its role in food security. The subsidy framework has helped keep fish affordable for Malaysian consumers while allowing fishermen to earn a living.

However, subsidy structures are evolving. The broader fuel subsidy rationalization programme affects the fishing industry’s access to subsidized diesel. Some operators receive full subsidies, others receive partial support, and the administrative requirements continue to change.

If you are a registered fisherman, ensure your documentation is current and you are accessing all available subsidies. If you are not registered or your registration has lapsed, addressing this should be a priority as it directly affects your fuel costs.

Why Fishing Gets Hit Harder Than Most Industries

No Route Optimization

A lorry operator can optimize routes, consolidate loads, or reduce empty runs. A fishing boat goes where the fish are. If the productive fishing grounds are 4 hours steaming time from port, you burn fuel getting there and getting back regardless of your catch. You cannot reroute to a closer destination if the fish are not there.

Catch Uncertainty

A lorry picks up a guaranteed load and delivers it. A fishing boat goes out hoping for a good catch. Some trips are profitable. Others barely cover fuel costs. This uncertainty means that higher diesel costs raise the break-even threshold for every trip. More trips become unprofitable.

Perishable Product, Limited Pricing Power

Fish prices at the wholesale market fluctuate based on supply. When boats bring in large catches, prices drop. When catches are poor, prices rise but you have less to sell. Fishermen generally cannot set their prices the way other businesses can. The market determines what your catch is worth, and that market does not adjust upward just because your diesel costs increased.

Seasonal and Weather Factors

Monsoon seasons restrict fishing days. During the northeast monsoon from November to March, many east coast fishermen cannot go out for weeks at a time. Fewer fishing days mean fewer chances to earn, while fixed costs like boat maintenance, crew retainers, and loan payments continue.

Practical Steps for Fishing Operators

Engine Maintenance Is Critical

Marine engines that are poorly maintained consume significantly more fuel. Fouled injectors, worn impellers, dirty fuel filters, and hull growth all increase fuel consumption. A clean hull alone can reduce fuel use by 10-15 percent compared to a heavily fouled hull. At current diesel prices, the cost of a hull cleaning or haul-out pays for itself quickly.

Know Your Break-Even Point

Every fishing trip has a break-even point - the minimum catch value needed to cover fuel, crew costs, ice, and other trip expenses. With higher diesel prices, this break-even point has moved up. Know your number. If today’s weather forecast or fishing reports suggest a trip is likely to fall below break-even, sometimes the smartest decision is to stay in port.

Consider Trip Efficiency

Some operators can improve trip efficiency by better planning. This might mean investing in better fish-finding equipment, sharing information with other boats about productive areas, or adjusting trip timing to match tidal and current patterns that affect fuel consumption.

Equipment Upgrades

Older engines are less fuel-efficient. A 20-year-old marine diesel engine may consume 15-25 percent more fuel than a more modern unit of similar horsepower. When diesel was RM2.15, that inefficiency was a minor concern. At RM3.35 or RM5.52, it represents hundreds or thousands of ringgit per month in wasted fuel.

Similarly, older boats with heavier hulls, less hydrodynamic designs, or deteriorated bottom paint create more drag and burn more fuel. Equipment age directly affects operating costs.

Financing for Fishing Operations

Fishing boats, marine engines, and related equipment represent substantial investments. For a coastal fisherman, even a used boat and engine package might cost RM50,000-100,000. Mid-size trawlers and deep-sea vessels cost far more.

When diesel costs have already increased your monthly expenses by RM3,000-9,000, paying cash for equipment replacement is often not feasible. Financing allows you to spread the cost over time while the equipment generates income from day one. If upgrading to a more fuel-efficient engine saves you RM500-1,000 per month in diesel, the financing payment may be partially offset by fuel savings.

Ing Heng Credit has been financing equipment for Malaysian businesses since 1985. With over 40 years of experience and more than 4,000 customers, we understand that fishing operators need practical, affordable financing solutions. We are KPKT licensed and we finance used boats and marine equipment because we know that is the reality of the industry. 0% deposit options are available.

The Reality Check

Diesel prices are unlikely to return to RM2.15. The subsidy restructuring is a long-term policy direction. Fishermen who adjust their operations, maintain their equipment, access available subsidies, and make smart financial decisions about their equipment will be better positioned to sustain their livelihoods.

Fishing remains essential. Malaysians consume fish as a staple protein, and the industry supports hundreds of thousands of livelihoods. The challenge is ensuring the economics still work for the people who go out and bring the fish home.
