Bycatch & interactions

<0.1% of lifts

Protected-species interactions and non-target bycatch as a share of pot lifts. Baited pots are passive, selective gear, so the overwhelming majority of lifts bring up target lobster and little else.

Worked example · Share of pot lifts · non-target
99.9% clean pot lifts Target lobster · 99.9% Bycatch / interaction · <0.1%
Share of pot lifts · non-target
The benchmark

Pot fishing is among the most selective wild-capture methods, with very low rates of non-target bycatch and protected-species interaction compared with trawl or net gear.

What it signals

Low, well-documented interaction rates are central to the fishery’s clean reputation and its export and certification credentials. Recording every interaction, however rare, is what lets the fishery prove its selectivity rather than merely assert it.

Data required to calculate
Non-target or protected interactionsno.Total pot liftsno.

Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.

How to improve it
01

Record every interaction, however rare, for a defensible record.

02

Use gear configurations that minimise entanglement risk.

03

Report and adapt quickly if any interaction hotspot emerges.

Questions & answers

What is bycatch & interactions?

Protected-species interactions and non-target bycatch as a share of pot lifts. Baited pots are passive, selective gear, so the overwhelming majority of lifts bring up target lobster and little else.

What data do you need to calculate bycatch & interactions?

You need: Non-target or protected interactions (no.), Total pot lifts (no.). Silo pulls each of these from the sources the operation already uses and keeps the figure current automatically.

What is a good bycatch & interactions benchmark?

Pot fishing is among the most selective wild-capture methods, with very low rates of non-target bycatch and protected-species interaction compared with trawl or net gear.

How do you improve bycatch & interactions?

Record every interaction, however rare, for a defensible record. Use gear configurations that minimise entanglement risk. Report and adapt quickly if any interaction hotspot emerges.
