Floating longline: an optimized technique for pelagic species in midwaters

Technological aspects and working principle

The floating longline is an advanced fishing technique based on the hydrostatic balance between buoyancy and weight. It is suitable for fishing pelargic fish. It can be found under various names such as swimming longline, floating longline or mole longline. Unlike classic bottom longlines, this system enables precise control of the hunting depth through:

1. Balanced system of floats and weights
2. Variable leader length 
3. Strategically placed reference points (every 5-6 hooks)

Optimal equipment configuration

Basic parameters:

• Base thickness: 0,90 mm
• Rig thickness: 0.50–0.60 mm
• Rig length: approx. 60 cm
• Hook spacing: approx. 5 m
• Hooks: Mustad 2310dt, sizes 11–13
• Float: Ø 18 mm (red or yellow)
• Sinker: 3 g (fixed)

Dynamic placement model

The implementation process requires strict adherence to the following stages:

1. Preliminary survey of the terrain (sonar, bathymetric maps)
2. Calculation of depth range according to the thermocline
3. Setting reference marks (kavicale every 50m)
4. Position control every 30-60 minutes

Statistical efficiency

Studies conducted in the Eastern Adriatic (2018-2022) show:

Operational recommendations

1. Bait selectivity: A combination of live bait or baits such as sardines, squid, bibi
2. Movement Tactics: Rotate positions every 2 hours
3. Environmental monitoring: Temperature and salinity monitoring
4. Security protocol: Regular control of the strength of connections

Conclusion: strategic advantages

The implementation of a floating longline brings three key advantages:

1. Increased selectivity towards target species
2. Reduced impact on the seabed (benthic ecosystems)
3. Improved energy efficiency of fishing operations
