Overfishing Definition: What is Overfishing?




First, it’s important to note that recreational fishermen are generally not responsible for overfishing. Overfishing primarily involves commercial fishing, where large-scale operations use massive nets to meet the ever-growing demand for fish. This is driven by increased global fish consumption, which has doubled over the last 50 years, and the growing world population.

Overfishing occurs when a region’s breeding stock becomes so depleted that fish populations can’t replenish themselves. This results in fewer fish each year or, at worst, the extinction of a fish species in a specific area. Overfishing is often associated with wasteful fishing methods that catch not only the target fish but also other unintended marine life.

Over 80% of fish are caught in such nets, leading to adverse consequences:

Increased Algae in the Water: Overfishing disrupts the natural balance, leading to uncontrolled algae growth and negatively impacting the oceans’ acidity, reefs, and plankton.

Destruction of Fishing Communities: Overfishing can devastate communities reliant on fishing for both their economy and primary protein source.

Tougher Fishing for Small Vessels: Large-scale overfishing makes it harder for smaller fishing operations to meet their quotas.

Ghost Fishing: Abandoned fishing gear poses a threat to marine life, trapping them even after being discarded.

Species Pushed to Near Extinction: Overfishing has led to the depletion of many fish species.

Bycatch: Non-target marine life caught as a byproduct of commercial fishing is known as bycatch and increases dramatically with overfishing.

Waste: Overfishing results in a significant loss of fish in the supply chain, with up to 20% of fish being wasted in the United States.

Furthermore, overfishing can lead to mislabeling, where seafood is falsely marketed, affecting consumer trust.


Why Overfishing Happens

Several factors drive overfishing, including inadequate regulations, unreported fishing activities, mobile processing of fish, and harmful subsidies. Government subsidies are a significant contributor, encouraging overfishing by rewarding the quantity of fish caught, rather than considering environmental impact.

According to the World Wildlife Fund, subsidies contribute to illegal fishing activities, piracy, slavery, and human trafficking. In 2018, it was reported that $22 billion, 63% of all fishing subsidies, supported practices encouraging overfishing.

The Role of Farmed Fish

Farmed fish were initially considered a solution to preserve wild fish populations while providing a source of income to communities affected by overfishing. However, the reality has proven to be different. Concentrated farming of fish leads to environmental pollution, heavy use of pesticides and drugs, and a decrease in the nutritional value of farmed fish. Farmed fish, in some cases, become less healthy than their wild counterparts.

Notably, farmed fish do not contain the same essential nutrients as their wild counterparts, which can pose health risks.

Countries Overfishing

While overfishing affects numerous countries, the main culprits tend to be less-developed nations in Asia and the undeveloped world. Notably, the United States appeared on a “shame list” in relation to overfishing, particularly of bluefin tuna, alongside Japan, Taiwan, China, South Korea, and Indonesia.

China stands out for providing significant subsidies promoting overfishing and underreporting its overseas fishing catch, especially in Africa.

Overfishing can lead to economic instability in local communities, as seen in New England and the Japanese fish market. These effects have far-reaching implications for marine ecosystems and people’s livelihoods.

The Severity of Overfishing

Overfishing is a critical issue that cannot be underestimated. For example, the Pacific bluefin tuna population has declined by 97%. This species plays a vital role in the marine food chain, and its extinction could disrupt the entire ecosystem.

Overfishing has broader ecological effects, including the depletion of smaller fish species that keep coral reefs healthy.

Alternatives to Combat Overfishing

To address overfishing, both government policies and technological solutions are necessary. Innovations, such as devices that reduce bycatch and waste, can contribute to sustainable fishing practices. Current regulations, quotas, and subsidies must be reevaluated to create more sustainable models for the fishing industry.

One promising alternative is the territorial use rights in fisheries management (TURF) system, which provides long-term fishing rights to individuals or collectives in specific areas. Fishermen with TURF have a vested interest in maintaining sustainable fishing practices. This market-driven approach promotes sustainability and is used in countries like Chile, Belize, Denmark, and the United States.

It’s crucial to address overfishing not only for environmental reasons but also for food security. The extinction of major protein sources could lead to increased competition for remaining resources, affecting global stability.

The detrimental consequences of overfishing are not confined to distant waters but can affect us all, making corrective measures essential.

Ryan Chen: Diving to Heal the Mind, Body and Spirit 

Ryan is a PADI Open Water Scuba Diver who was in a tragic accident as a teenager that left him paralysed. He found healing and clarity through scuba diving with his dive buddy Kent Yoshimura – so much so that during one scuba diving trip he and Kent ended up creating their current company Neuro Gum – a collection of functional gum and mints that help you get energised, calm or focused that has now led him to be named on Forbes 30 under 30.

“Scuba diving was one of the ways I learned that I can do anything, I just have to do it differently,” Chen says, “Scuba diving is one of those things that can change your whole framework. There’s no cooler feeling than taking that first breath underwater. All of a sudden you have this superpower, to breathe underwater and explore.”

Scuba diving continues to be his physical and mental therapy he continually seeks out amidst his busy entrepreneurial life. Now, with Neuro a national success and leading wellness brand in the United States, Chen has kept up his diving, and remained close to PADI as an organisation. Neuro even has a collaboration with PADI’s coral reef restoration project coming up—a special pack of Neuro, with proceeds going to PADI’s non-profit foundation.

The life of a Great White Shark



Great White Shark

The great white shark, known scientifically as Carcharodon carcharias, embodies the apex predator of the ocean. This majestic creature’s life is a testament to survival, adaptability, and the intricate balance of the marine ecosystem.

Born in the waters off coastal regions, a great white shark begins its life as a pup within the safety of nurseries, typically found in warm, shallow waters. The pups, measuring around 5 feet in length at birth, are immediately equipped with an innate instinct for survival.

Great White Shark

As they grow, great whites embark on a journey, venturing into deeper and cooler waters, often covering vast distances across the ocean. These apex predators are perfectly adapted hunters, relying on their impressive senses to detect prey. Their acute sense of smell, aided by specialized sensory organs known as ampullae of Lorenzini, helps detect the faintest traces of blood in the water from several miles away.

Feeding primarily on seals, sea lions, and other marine mammals, great whites are known for their powerful jaws lined with rows of razor-sharp teeth. Their hunting techniques often involve stealth, utilizing their streamlined bodies to approach prey from below and striking with incredible speed and force.

Great White Shark

Despite their fearsome reputation, great whites play a crucial role in maintaining the health of marine ecosystems. As top predators, they help regulate the population of prey species, preventing overpopulation that could disrupt the balance of the food chain.

Reproduction among great white sharks is a slow and careful process. Females reach sexual maturity between 12 and 18 years of age, while males mature earlier, around 9 to 10 years old. Mating occurs through complex courtship rituals, with females giving birth to a small number of live pups after a gestation period of about 12 to 18 months.

Great White Shark

However, the life of a great white shark is not without challenges. Human activities, including overfishing, pollution, and habitat destruction, pose significant threats to their population. Additionally, despite their formidable presence, great whites are vulnerable and face dangers from entanglement in fishing gear and accidental bycatch.

Despite these challenges, great white sharks continue to inspire awe and fascination among scientists and nature enthusiasts. Their presence in the ocean serves as a reminder of the delicate balance and interconnectedness of marine life, emphasizing the need for conservation efforts to protect these magnificent creatures for future generations to admire and study.
