“…It has a much lower ecosystem impact than some fishing methods (trawls and gill nets), which are significantly responsible for bycatch and destructive benthic impact (Aydın et al 2016). Traps and lift nets tried as alternatives were not satisfactory in terms of catch efficiency (Altınağaç et al 2004;Şahin 2004;Sağlam et al 2017). Divers display gathering behavior focused solely on the target species and tend to collect large size individuals of high economic value (Aydın et al 2016).…”

Hookah diving is a traditional fishing method based on the hand collection of commercial benthic organisms. Fishers continue their profession without paying attention to their physical health and psychophysical fitness. Ignoring the diving safety and decompression rules underwater, using improvised diving systems, and economic concerns carry risks that can result in death. The long-term sustainability of work depends on nations’ ability to control fishing practices and promote good management. This study discusses the current situation of hookah divers in Turkey based on official statistics from the ministry and face-to-face interviews with hookah divers. The data were subjected to strengths, weaknesses, opportunities, and threats (SWOT) analysis and synthesised with the literature for strategic analysis. The sector’s contribution to the national economy, economic satisfaction of divers, and supporting rural employment were evaluated as strengths. Lack of expertise in the professional career and complex laws were identified as threats that require urgent solutions. Multidirectional national efforts are needed for sustainable fishing, including stakeholder networking, diving safety, hookah equipment, underwater fishing strategies, training curricula and professional career development. Our findings offer strategic and planning approaches for the sustainable development of hookah diving in Turkey.

The effects of the claw size used on the shoes of the traditional sea snail beam trawl and the effect of the steel wire used between the shoes on catching efficiency were investigated on the Samsun coast of the Black Sea. A traditional beam trawl with steel wire and with a claw length of 5.5 cm (T) was compared to modified beam trawls with steel wire (M1) and without steel wire (M2) with a claw size of 0.5 cm. The operations were performed as T-M1 and then T-M2 hauls using the dual parallel towing method. There was no significant difference in the amount of target species in the comparison of T (70.12) and M1 (63.23) according to the average catch per unit effort (CPUE, kg h -1 ) values obtained (P = 0.399). In the T-M2 comparison, 49% higher CPUE value was achieved with the T (77.37) beam trawl and there was a significant difference in terms of targeted species (P = 0.002). As a result, it was observed by underwater observations that steel wire on the beam trawl had a negative effect on the ground, and it was found that the bycatch ratio with the T beam trawl was higher than that with the modified beam trawl.
