How to catch Serpent eel

Ophisurus serpens (Linnaeus, 1758)

About Serpent eel fishing

The serpent eel belongs to the family Ophichthidae and features an extremely elongated, snake-like body with a tapering snout, small pectoral fins, and no caudal fin. Its colouration is typically olive green to brown above with a paler belly and distinctive dark head pores. Growing to substantial lengths, it inhabits brackish and marine waters down to three hundred metres, residing over soft sandy and muddy bottoms of the continental shelf. By day, it remains buried tail-first in the sediment with only its head exposed, emerging at night to hunt crustaceans and small fish. While rarely targeted commercially as a primary catch, it presents an unusual challenge for specialized nocturnal anglers.

How to catch Serpent eel

Tips for catching Serpent eel

Targeting this nocturnal predator requires patience and night-fishing tactics along sandy or muddy coastal stretches where soft sediment prevails. Since the fish spends daylight hours completely buried in the substrate, presentations must coincide with its nocturnal foraging activity using robust tackle equipped with heavy grips to hold bottom in the surf zone. Safe and effective presentations rely on ledgered strips of oily fish or large marine worms fished directly on or near the sea floor. Persistence is key, as these resident eels maintain strict burrow fidelity, requiring anglers to place baits close to known holding areas during the warmer summer and early autumn months.
