This can be a very diverse charter as there are a range of good fishing areas to choose from using light-medium tackle for a variety of species including large Sharks. Various game fish such as Yellowtail, Snoek, Skipjack & Katonkel arrive in massive shoals off Cape Point annually.

Yellowtail is an esteemed game fish that is a fast and powerful predator and gives an excellent fight. Snoek is a fierce shoaling predator that is well respected by all who catch it and this is great fishing for the whole family. Cape Point is also known for good reefs that produce Red Roman, Cape Salmon, Hottentot and a range of Rays, Skates and Sharks.

Alternatively, we could head into False Bay towards Seal Island, world famous for the great white Shark breaching predations and home to a population of up to 70 000 Cape Fur Seals. This dense population of Seals, in turn, attracts a large number of White Sharks and one can often see these phenomenal apex predators clear the water while hunting their furry prey.

In and around this area, we target fish species such as Kob, Steenbras, Roman, Yellowtail and a wide variety of Sharks. All Sharks are caught on a strict catch and release basis.

False Bay and around Cape point is home to an abundance of marine wild life and is one of the few places where you can witness such an extensive range of marine life. On our charters, we often encounter pods of Dolphins, Southern Right Whales, Cape Fur Seals, African Penguins and the Great White Shark. We also encounter Humpback & Brydes Whales and the occasional Orca can be seen hunting Dolphins along the spectacular coastline.

Big Game Fish & Tuna Charter

The Cape waters have a worldwide reputation for Tuna fishing. The sheer power of a big Yellowfin, a true bluewater game fish, has to be seen to be believed and the memories of the powerful runs of a decent size Yellowfin Tuna will live on in any anglers mind forever. From October, oceanic tunas start arriving in large shoals off Cape Point and continues until June.

On this charter we target Yellowfin, one of the world’s toughest fighting fish, Big Eye and Longfin Tuna. Yellowfin and Big Eye Tuna of over a 100 kg’s are landed but the average size of the fish is 50kg – 70kg. Southern Bluefin Tuna have recently made an appearance in the Cape waters and the occasional one has been landed

The best method to catch Tuna is either by trolling lures behind the boat or creating a chum line and fishing with bait while drifting in the current. Often, other pelagics like Skipjack, Katonkel and Dorado (Mahi-Mahi) are landed in the same area.

Hooking up with one of the rulers of the blue world, the Mako or Blue shark gives a great fight but these are caught on a strict catch & release basis only. Although not common, Marlin can be caught at certain times of the year.

We use top of the range Shimano Tiagra reels and Black Magic stand up harnesses because of their comfort, quality and proven durability when fighting fish.

This full day fishing charter generally begins early when we cast off from our Private Marina and head up to 40 nm (approximately 75 km’s) from Cape Point to the tuna grounds.

Marine Eco Life Charters

False Bay is flanked by Cape Town’s iconic Table Mountain range and is one of the largest embayment’s on the tip of the South African continent. Along the coast line towards the Cape of Good Hope, rugged rocks, caves and sheer cliffs towering more than 200 metres above the sea and cutting deep into the ocean, provide spectacular views from the seaward side.

False Bay and around Cape Point is home to an abundance of marine wild life and is one of the few places where you can witness such an extensive range of marine life. We often encounter pods of Dolphins, Cape Fur Seals, African Penguins and the Great White Shark. Certain times of the year we also encounter Southern Right Whales, Humpback & Brydes Whales and the occasional Orca can be seen hunting the Dolphins along the spectacular coastline.

Deep Sea Fishing

Deep-sea fish are fish that live in the darkness below the sunlit surface waters that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout.

Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone; meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. This area is also where nutrients are most abundant. The bathypelagic and abyssopelagic zones are aphotic, meaning that no light penetrates this area of the ocean. These zones make up about 75% of the inhabitable ocean space.

The epipelagic zone (0–200m) is the area where light penetrates the water and photosynthesis occurs. This is also known as the photic zone. Because this typically extends only a few hundred meters below the water, the deep sea, about 90% of the ocean volume, is in darkness. The deep sea is also an extremely hostile environment, with temperatures that rarely exceed 3 °C (37.4 °F) and fall as low as −1.8 °C (28.76 °F) (with the exception of hydrothermal vent ecosystems that can exceed 350 °C, or 662 °F), low oxygen levels, and pressures between 20 and 1,000 atmospheres (between 2 and 100 megapascals).


In the deep ocean, the waters extend far below the epipelagic zone, and support very different types of pelagic fishes adapted to living in these deeper zones.

In deep water, marine snow is a continuous shower of mostly organic detritus falling from the upper layers of the water column. Its origin lies in activities within the productive photic zone. Marine snow includes dead or dying plankton, protists (diatoms), fecal matter, sand, soot and other inorganic dust. The “”snowflakes”” grow over time and may reach several centimetres in diameter, travelling for weeks before reaching the ocean floor. However, most organic components of marine snow are consumed by microbes, zooplankton and other filter-feeding animals within the first 1,000 metres of their journey, that is, within the epipelagic zone. In this way marine snow may be considered the foundation of deep-sea mesopelagic and benthic ecosystems: As sunlight cannot reach them, deep-sea organisms rely heavily on marine snow as an energy source.

Some deep-sea pelagic groups, such as the lanternfish, ridgehead, marine hatchet fish, and light fish families are sometimes termed pseudoceanic because, rather than having an even distribution in open water, they occur in significantly higher abundances around structural oases, notably seamounts and over continental slopes. The phenomenon is explained by the likewise abundance of prey species which are also attracted to the structures.

Hydrostatic pressure increases by 1 atmosphere for every 10m in depth. Deep-sea organisms have the same pressure within their bodies as is exerted on them from the outside, so they are not crushed by the extreme pressure. Their high internal pressure, however, results in the reduced fluidity of their membranes because molecules are squeezed together. Fluidity in cell membranes increases efficiency of biological functions, most importantly the production of proteins, so organisms have adapted to this circumstance by increasing the proportion of unsaturated fatty acids in the lipids of the cell membranes. In addition to differences in internal pressure, these organisms have developed a different balance between their metabolic reactions from those organisms that live in the epipelagic zone. David Wharton, author of Life at the Limits: Organisms in Extreme Environments, notes “”Biochemical reactions are accompanied by changes in volume. If a reaction results in an increase in volume, it will be inhibited by pressure, whereas, if it is associated with a decrease in volume, it will be enhanced””. This means that their metabolic processes must ultimately decrease the volume of the organism to some degree.

Most fish that have evolved in this harsh environment are not capable of surviving in laboratory conditions, and attempts to keep them in captivity have led to their deaths. Deep-sea organisms contain gas-filled spaces (vacuoles). Gas is compressed under high pressure and expands under low pressure. Because of this, these organisms have been known to blow up if they come to the surface


The fish of the deep-sea are among the strangest and most elusive creatures on Earth. In this deep dark unknown lie many unusual creatures that have yet to be studied. Since many of these fish live in regions where there is no natural illumination, they cannot rely solely on their eyesight for locating prey and mates and avoiding predators; deep-sea fish have evolved appropriately to the extreme sub-photic region in which they live. Many of these organisms are blind and rely on their other senses, such as sensitivities to changes in local pressure and smell, to catch their food and avoid being caught. Those that aren’t blind have large and sensitive eyes that can use bioluminescent light. These eyes can be as much as 100 times more sensitive to light than human eyes. Also, to avoid predation, many species are dark to blend in with their environment.

Many deep-sea fish are bioluminescent, with extremely large eyes adapted to the dark. Bioluminescent organisms are capable of producing light biologically through the agitation of molecules of luciferin, which then produce light. This process must be done in the presence of oxygen. These organisms are common in the mesopelagic region and below (200m and below). More than 50% of deep-sea fish as well as some species of shrimp and squid are capable of bioluminescence. About 80% of these organisms have photophores – light producing glandular cells that contain luminous bacteria bordered by dark colourings. Some of these photophores contain lenses, much like those in the eyes of humans, which can intensify or lessen the emanation of light. The ability to produce light only requires 1% of the organism’s energy and has many purposes: It is used to search for food and attract prey, like the anglerfish; claim territory through patrol; communicate and find a mate; and distract or temporarily blind predators to escape. Also, in the mesopelagic where some light still penetrates, some organisms camouflage themselves from predators below them by illuminating their bellies to match the colour and intensity of light from above so that no shadow is cast. This tactic is known as counter illumination.

The lifecycle of deep-sea fish can be exclusively deep water although some species are born in shallower water and sink upon maturation. Regardless of the depth where eggs and larvae reside, they are typically pelagic. This planktonic — drifting — lifestyle requires neutral buoyancy. In order to maintain this, the eggs and larvae often contain oil droplets in their plasma. When these organisms are in their fully matured state they need other adaptations to maintain their positions in the water column. In general, water’s density causes up thrust — the aspect of buoyancy that makes organisms float. To counteract this, the density of an organism must be greater than that of the surrounding water. Most animal tissues are denser than water, so they must find equilibrium to make them float. Many organisms develop swim bladders (gas cavities) to stay afloat, but because of the high pressure of their environment, deep-sea fishes usually do not have this organ. Instead they exhibit structures similar to hydrofoils in order to provide hydrodynamic lift. It has also been found that the deeper a fish lives, the more jelly-like its flesh and the more minimal its bone structure. They reduce their tissue density through high fat content, reduction of skeletal weight — accomplished through reductions of size, thickness and mineral content — and water accumulation makes them slower and less agile than surface fish.

Due to the poor level of photosynthetic light reaching deep-sea environments, most fish need to rely on organic matter sinking from higher levels, or, in rare cases, hydrothermal vents for nutrients. This makes the deep-sea much poorer in productivity than shallower regions. Also, animals in the pelagic environment are sparse and food doesn’t come along frequently. Because of this, organisms need adaptations that allow them to survive. Some have long feelers to help them locate prey or attract mates in the pitch black of the deep ocean. The deep-sea angler fish in particular has a long fishing-rod-like adaptation protruding from its face, on the end of which is a bioluminescent piece of skin that wriggles like a worm to lure its prey. Some must consume other fish that are the same size or larger than them and they need adaptations to help digest them efficiently. Great sharp teeth, hinged jaws, disproportionately large mouths, and expandable bodies are a few of the characteristics that deep-sea fishes have for this purpose. The gulper eel is one example of an organism that displays these characteristics.

Fish in the different pelagic and deep water benthic zones are physically structured, and behave in ways, that differ markedly from each other. Groups of coexisting species within each zone all seem to operate in similar ways, such as the small mesopelagic vertically migrating plankton-feeders, the bathypelagic anglerfishes, and the deep water benthic rattails.”

Ray finned species, with spiny fins, are rare among deep sea fishes, which suggests that deep sea fish are ancient and so well adapted to their environment that invasions by more modern fishes have been unsuccessful. The few ray fins that do exist are mainly in the Beryciformes and Lampriformes, which are also ancient forms. Most deep sea pelagic fishes belong to their own orders, suggesting a long evolution in deep sea environments. In contrast, deep water benthic species are in orders that include many related shallow water fishes.”
