Butler, J.A., Heinrich, G.L. [email protected] 904 602-3885 This study determined that 73.2% of diamondback terrapins could have been prevented from entering crab pots if bycatch reduction devices (BRDs) had been used. Additionally, there was no significant difference in the sex, size or number of crabs in pots fitted with BRDs.

Endangered Species Research Inter-Research Science Publisher Nordbünte 23 21385 Oldendorf/Luhe, Germany Inter-Research Science Publisher Tel: (+49) (0)4132-7127 Fishing-related seabird mortalities are considered the most pervasive threat to seabird conservation status. Specifically, warp wire interactions (warp strike) and net captures of trawl […]

Submitted by morgaac on July 25, 2012 – 14:22 Evaluation of a pound net leader designed to reduce sea turtle bycatch There was no significant difference in the harvest weight or size selectivity of finfish between the two nets (control and experimental) . During the study, 21 sea turtles interacted with the control net, while […]

Submitted by morgaac on January 21, 2011 – 17:27 There were no differences in the mean length at capture, but signficantly more swordfish were caught on the monofilament gangions. No signficant difference in catch rates between gangions for white marlin. Alternative leader design

Fratto, Z.W., Barko, V.A. and Scheibe, J.S. Chelonian Conservation and Biology Wisconsin-type fyke nets were modified in an effort to reduce the incidental bycatch of turtles, without significantly reducing the catch of targeted fish species.  The tests were conducted in three rivers (Missouri, Mississippi and Gasconade) in Missouri.  The net was modified by adding four […]

Submitted by Kate McClellan on July 30, 2012 – 14:29 sunfish, bullheads, yellow perch, rock bass, black crappie 77% of fish escaped through large hole in net 60% of turtles escaped through large hole in net

Submitted by morgaac on April 14, 2010 – 17:10 Bigeye and yellowfin tuna Nylon monofilament leaders had higher catch rates of bigeye tunas when compared to wire leaders, but had no effect on yellowfin catch Wire leaders had higher catch rates of sharks when compared to nylon monofilament leaders Alternative leader design

Draft SLED report for RLIAC https://doi.org/10.3354/esr00155 Pot-gear modifications or sea lion exclusion devices (SLEDs) were tested in the Australian West Coast rock lobster pot fishery to reduce bycatch of Australian sea lion pups and juveniles. Although low levels of interactions in this preliminary study make testing the efficacy of the gear modification difficult, early tests […]

Hatfield, B., J. Ames, J. Estes, M. Tinker, A. Johnson, M. Staedler, and M. Harris Endangered Species Research Sea otters are caught and drowned in fishing pots and traps.  Live California sea otters were exposed to finfish traps, lobster traps, and mock Dungeness crab traps in captive trials.  Researchers found that the otters attempted to […]

Radzio, T.A. and Roosenburg, W.M. [email protected]; [email protected] Field studies were conducted in the Patuxent River, Maryland, to quantify the bycatch of cloth-funnel eel pots with small and large openings, and to test the effect of a prototype bycatch reduction device on bycatch and catch.  The bycatch reduction device consisted of a 77 mm PVC ring […]

National Research Council (CNR), Institute of Biological Resources and Marine Biotechnologies (IRBIM) of Ancona, Largo Fiera della Pesca, 1 – 60125 Ancona, Italy, [email protected] In the Mediterranean Sea, trawl nets have high levels of bycatch of protected species, including the loggerhead turtle (Caretta […]

Submitted by morgaac on June 8, 2011 – 13:26 No significant differences in catch rates between the two set types was found Statistically more sickle pomfret and fewer wahoo, dolphinfish, blue marlin, striped marlin and shortbill spearfish were caught on the experimental compared to the control sets

Submitted by morgaac on July 21, 2010 – 14:46 Crab catch rates were 11% higher when the 5×10 cm excluder design was used in 1994 (multiple sites) and 49% higher in 1995 (single site) Modified traps with a 5X10 cm rectangular frame caught 2 out 15 terrapins during 1992 and 5 out of 51 terrapins […]
