What is Estuary and River Fishing?
Estuary and river fishing is a popular and diverse style of angling that takes place in transitional water systems where freshwater rivers meet the saltwater of the ocean. These unique environments are known as estuaries, and they create a rich, brackish water habitat that is home to a wide variety of fish species. As the salinity of the brackish water changes with the tides and the amount of freshwater flowing in from the river, this creates a highly dynamic and nutrient-rich environment.
Why Choose Estuary and River Fishing?
While the Northern Territory is renowned for its diverse fishing options, ranging from bluewater game fishing for marlin to casting for giant trevally on remote reefs, estuary and river fishing stands out as a unique and often more challenging pursuit. It’s a style of fishing defined by its environment and the distinct predatory nature of the species that inhabit it. The estuaries are not just open water. They are a complex mosaic of different habitats, including:
- Mangrove-lined creeks: The tangled root systems of mangrove trees provide excellent cover and a rich food source for many fish.
- Mud and sand flats: These shallow areas are often exposed at low tide and are full of invertebrates like crabs and yabbies, which are a key food source for fish.
- Deep channels and holes: These are the main thoroughfares for fish and provide a safe haven during low tide or when the current is strong.
- Rock bars and snags: Submerged rocks, fallen trees, and other debris provide ambush points for predatory fish.
- Tidal Influence: The tides are the lifeblood of an estuary. The movement of water brings in baitfish, stirs up nutrients, and influences where fish are located. Anglers must understand the tides to be successful, as the best fishing often occurs on a rising or falling tide.
How is Estuary and River Fishing Different from Other Kinds of Fishing in Australia?
Estuary and river fishing is a more intimate and technical pursuit. It requires an understanding of the local environment, a knowledge of where the fish are likely to be hiding, and the ability to make precise casts into tight spaces. There is no end to the variety of techniques that you can utilise in this environment and the types of fish will astound you.
Estuary and River Fishing Techniques
Estuary and river fishing is a very versatile form of angling, and a wide range of techniques can be used:
- Lure Fishing: This is a very popular and active method. Anglers use a variety of lures, from hard-bodied minnows and poppers to soft plastics and jigs, to imitate baitfish. Precision casting is crucial to land the lure in tight spaces near structure.
- Live Baiting: Using live prawns, mullet, or other baitfish is a highly effective method for targeting larger, more wary predators.
- Bait Fishing: Simple and effective, this involves using fresh or frozen baits like prawns, worms, or squid to catch a wide range of species.
- Trolling: For covering a lot of water and finding actively feeding fish, trolling lures along the river channels can be very productive.
The Fish in Estuaries of Arnhem Land
The species you can catch in an estuary vary greatly depending on the geographical location (e.g., tropical vs. temperate climates). However, many species are known to use estuaries as a nursery, a feeding ground, or a permanent home.
Common estuary species in NT Australia include:
- Barramundi: A prized sportfish in the tropical north, known for its powerful fight and spectacular aerial displays, “barra” are a bucket-list fish for any angler. You’ll find them in both saltwater and freshwater, and a “meter-plus” barra is the ultimate prize.
- Mangrove Jack: An aggressive predator that hides in structure and strikes with incredible force.
- King Threadfin Salmon: A hard-fighting species that is also a fantastic table fish.
- Mulloway (Black Jewfish): A large, powerful fish often found in deeper holes and channels.
