HELCOM FISH PRO III Meeting, Helsinki, Finland, 12th to 14th February 2019

Pilot study 2017-2018

Aim:

1. Testing methods for monitoring of recreational fisheries in Polish marine waters, 2. Identification of fishing areas, 3. Identification of potential issues, 4. Analysis of formal procedures, law.

Two moduls: trolling and shore fishing. Target species: salmon, sea trout, cod, eel.

Polish coast

Roving creel survey

• Harbors (trolling),
• On-board (trolling),
• Shore (surfcasting).

Mobile App

Interviews – on-site survey

Off-site survey

Web-based survey

• started in March 2018,
• concers only 2017,
• targeting sea recreational fishing.

Self-sampling

Concers only trolling fishing

• started in November 2017,
• volountary participation,
• inviting trolling boat skippers,
• targeting salmon and sea trout.

Two locations: 1. Hel 2. Gdańsk (Górki Zachodnie) Why?

• potential high importance
• available infrastructure

CCTV monitoring results - Hel

• Fig. 3. Number of trolling trips observed in Hel harbor, since 1st of January to 3rd of February 2018.

N = 112 fishing days (trips)

Trolling

• Two salmon fishing areas,
• Four main harbors (Hel, Gdynia, Gdańsk Górki Zachodnie, Kołobrzeg),
• Low level of trust,
• Very closed community,
• Interviews - response rate harbor-dependent.

Surfcasting

• Distributed along Polish coast (not aggregated),
• High level of trust,
• High response rate.

Preliminary findings

• First task, start with information campaign,
• On-site surveys – time - and cost-consuming vs. obtained results,
• Web-based survey – low response rate.
