| NOAA SEAMAP 2015 Cruise Stations collected from the R/V Oregon II during the 2015 NOAA Seamap Fall Groundfish Survey in the Gulf of Mexico (OtolithHypoxia project) | Seamap 40' net | |
| Mg/Ca ratios in Echinoderms collected near western Antarctica on NBP12-10 (Jan. 1 to Feb. 9, 2013) and LMG13-12 (Nov. 22 to Dec. 20, 2013) | 1.5 meter width Blake Trawl | |

| Gulf of Maine Inshore Trawl Survey: Length Frequency Data from F/V Robert Michael, F/V Tara Lynn NEC-JS2000-1 along the Maine and New Hampshire coasts from 2000-2004 (NEC-CoopRes project) | The net is a scaled down version of the most common shrimp and modified shrimp net design used by Maine's dragger fleet. The net was designed by the vessel owner and his net designer, Jeff Flagg, to fish effectively, be easily maintained, and be towed by vessels ranging from 45 - 70 ft. with nominal horsepower. Net tapers were cut to permit the shape of the net to get maximum height, while allowing the net to remain tight on the bottom. The net is shackled from the footrope to the frame using two 3/8-inch shackles to a banded wire that runs parallel with the footrope. Heavy rubber wing bobbins retard bottom wing lift. The top leg is 3/8th inch wire, 15 fathoms long, and the bottom leg is 15 fathoms. The net is constructed of 2 inch mesh overall with a 1/2 inch mesh liner in the cod end. Doors are #7.5 Bisons. The 70 ft. footrope includes 70 feet of 6 inch cookies. Chain sweeps were not used. Between surveys, the net is sent back to the manufacturer where it is returned to specification. | Trawl_custom |

| Scup and windowpane flounder expanded length frequency for study of scup and windowpane flounder catch using scup gear and a Large Mesh Belly Panel (LMBP), October 2015 (Windowpane Bycatch project) | Experimental net with the large mesh belly panel and small mesh typical of that used in scup fishery along the East Coast of the US. The nets used for this project were 286 x 16cm, 4-seam, 3-bridle standard otter trawls. The 286 x 16cm refers to the circumference of the fishing circle (286 meshes around of 16 cm mesh to form the circle) and nets of this size are appropriate for vessels with horsepower in the range of 400hp to 550hp. The net was constructed with 16cm (full mesh) webbing in the wings and jibs. The bunt and the 1st bottom belly were constructed from 12 cm mesh. The top square, top bellies, and the side panels were constructed from 8cm Dyneema webbing. The last belly section, top, and bottom were 6cm PE webbing. The codend was constructed of 5" regulation mesh used in the scup fishery. Flotation for this trawl was provided by 48 -8" floats mounted on the headrope. The sweep of the trawl was constructed of 2-3/8" and 3" rubber discs on wire rope. The sweep was comprised of three pieces totaling 2400cm or 78.72 feet in length. The headrope height was approximately 16 feet high. This net was then modified by Jon Knight of Superior Trawl to include the LMBP. The large mesh panel for this project was made from 5mm poly webbing and the mesh size was 80cm or approximately 32 inches knot-center to knot-center diamond mesh. The actual panel was 2 meshes deep and was sewn into the standard 12cm (5”) mesh of the 1st bottom belly using a "saw-toothing" technique. Similar to the SNECRI project, this results in an effective area for fish escapement of 3 full 32 inch meshes, or an opening in the belly of the net that is approximately 8 feet deep from front to back. The LMBP attached approximately 1 foot (2.5 meshes/12cm) behind the footrope and extended widthwise across the entire belly of the net (from gore to gore) for 30 meshes of 32 inch diamond mesh. | |
