Submitted by lweiss on December 13, 2019 – 10:30 Escape behavior of haddock can be triggered by mechanical stimulation and were slightly affected by light. Cod did not react significantly to the presence of mechanical stimulation or LED light stimulation.

Porsmoguer, S.B., Banaru, d., Boudouresque, C.F., Dekeser, I. and C. Almarcha AlmarchabaAix-Marseille University, CNRS, Toulon University, IRD, MIO (Mediterranean Institute of Oceanography) UM110, Campus de Luminy, Case 901,13288 Marseille Cedex 09, Two models of high field strength neodymium magnets (N35-Ni and N35-NdFeB types) were tested to determine their ability to deter sharks incidentally captured in […]

Submitted by morgaac on February 24, 2012 – 12:33 Circle hooks penetrated the lip more frequently (73%) than the J-hook (41%). Hook location was correlated with immediate mortality; all mortalities involved hook damage to the visceral region. A 10% post-release mortality was seen with both hook types.

Submitted by morgaac on September 15, 2011 – 16:35 There were no significant differences in catch rates between hook types but squid bait caught significantly more blue and silky sharks and dolphinfish.

Submitted by morgaac on December 1, 2011 – 08:22 No significant differences in catch rates of the target species were found between hook types. The highest catch rates for tunas were found on circle hooks size 15. Squid and jack mackerel bait had the highest catch rates for tunas. Significant differences between J and circle […]

Trippel, E.A., Strong, M.B., Terhue, J.M. and J.D. Conway Canadian Journal of Fisheries and Aquatic Sciences Field testing was conducted  in the lower Bay of Fundy during 1996 and 1997 to determine the effectiveness of acoustic alarms (Netmark 1000) in reducing bycatch rates of harbor porpoises in gillnets. Alarms were spaced 100 m apart along […]

Harcourt, R., Pirotta, V., Heller, G., Peddemors, V. and D. Slip Endangered Species Research Department of Biological Sciences, Macquarie University, Sydney, NSW 2109, Australia; [email protected] Acoustic deterrents were tested for their ability to deter humpback whales (Megaptera novaeangliae) from potential sources of entanglement. Low frequency (3 kHz, 135 +/- 5 db, 5 s emission interval […]

Aquatic Conservation: Marine and Freshwater Ecosystems Fish Ecology and Conservation Physiology Laboratory, Department of Biology, Carleton University, Candada [email protected] A population viability analysis and evaluations of bycatch mitigation techniques were used to investigate the impact of bycatch mortality on the populations of four freshwater turtles […]

Aquatic Conservation: Marine and Freshwater Ecosystesm Joshua Hatch, Integrated Statistics, Inc., 16 Sumner St., Woods Hole, MA 02543, USA. Email: [email protected] Fisheries observer data from six gear types operating in the US Northeast and mid-Atlantic were analysed for seabird interactions. Between 1996 and 2014 an estimated 48,821 seabirds interacted with commercial fishing gear. This resulted […]

Submitted by morgaac on September 30, 2015 – 14:33 Target catch rates were not affected Integrated weight longlines paired with streamer lines eliminated surface foraging and shearwater catch by 97%; integrated weigh longlines reduced surface forager catch rates by 91% and unweighted longlines with paired streamer by 98% Bird-scaring devices Sub-surface bait setting

Jimenez, S., Phillips, R.A., Brazeiro, A., Defeo, O., Domingo, A. [email protected] This study examined the spatial and temporal variations in bycatch rates of four species of great albatrosses. Observer data was obtained from the Uruguayan pelagic longline fleet and Japanese vessles operating in Uruguay. Vessel operational practices and habitat variables affected bycatch rates, including: setting […]

Submitted by morgaac on August 12, 2015 – 20:17 Straight 16/0 circle hooks caught the most blue sharks in the Azores longline swordfish and blue shark fishery, followed by offset 18/0 circle hooks. Offset 16/0 circle hooks caught the fewest blue sharks. There was no significant difference in the number of loggerhead sea turtles caught […]

Submitted by morgaac on July 31, 2012 – 10:45 Circle hook performance in the Uruguayan pelagic longline fishery Albacore catches increased with circle hooks on both types of longline. Shortfin mako shark catch rates increased with circle hooks on the American style longlines. American style longlines – no significant difference in catch rates for blue […]
