Fishermen have long debated whether extracting a deeply embedded lure or severing the line proves more beneficial for the fish. Mike discovered an article on the CBC website addressing this exact question with real science.
What the Research Says
Researchers at Carleton University's Cooke Lab determined that fish successfully dislodge lures within relatively brief timeframes, regardless of hook depth. According to their findings: "By and large, most of the lures were shed in a relatively short period of time. Barbless hooks usually came out within 24 hours. Deeply hooked lures also came out relatively quickly, although retained longer."
Survival Factors
Drawing from years of observing fish and anglers at Dogskin, survival factors influenced by angler behavior include:
- Duration the fish remains airborne
- Intensity of the fight
- Degree of protective coating loss (particularly for pike)
- Capture depth and retrieval speed
Best Practice: Cut the Line
Understanding that fish naturally shed lures suggests that cutting the line near a deeply hooked catch maximizes survival odds by returning the fish to water immediately. Spending time trying to extract a deep hook causes far more damage than letting the fish shed it naturally.
For trophy fish, photograph appropriately, measure while minimizing skin contact, and release promptly. The fish — and the next angler — will thank you.
