NMFS is amending the turtle excluder device (TED) regulations that require most shrimp trawlers to use TEDs in the southeastern Atlantic and the Gulf of Mexico to reduce the incidental capture of endangered and threatened sea turtles during shrimp trawling. Specifically, NMFS is allowing the use of a double cover flap TED with a modified flap design. This modification will allow the use of a flap that extends up to 24 inches (61 cm) past the posterior edge of the TED frame. This modification has been tested and meets the regulatory requirements for efficiency at releasing sea turtles.
Effective May 27, 2004.

All sea turtles that occur in U.S. waters are listed as either endangered or threatened under the Endangered Species Act of 1973 (ESA). The Kemp's ridley (Lepidochelys kempii), leatherback (Dermochelys coriacea), and hawksbill (Eretmochelys imbricata) turtles are listed as endangered. The loggerhead (Caretta caretta) and green (Chelonia mydas) turtles are listed as threatened, except for breeding populations of green turtles in Florida and on the Pacific coast of Mexico, which are listed as endangered.
Sea turtles are incidentally taken and killed as a result of numerous activities, including fishery trawling activities in the Gulf of Mexico and along the Atlantic seaboard. Under the ESA and its implementing regulations, taking sea turtles is prohibited, with exceptions identified in 50 CFR 223.206, or if in accordance with the terms and conditions of a biological opinion issued under section 7 of the ESA or an incidental take permit issued under section 10 of the ESA. The incidental taking of turtles during shrimp or summer flounder trawling is exempted from the take prohibition if the conservation measures specified in the sea turtle conservation regulations (50 CFR 223) are followed. The regulations require most shrimp trawlers and summer flounder trawlers operating in the southeastern United States (Atlantic area, Gulf area, and summer flounder sea turtle protection area, see 50 CFR 223.206) to have a NMFS-approved TED installed in each net that is rigged for fishing to provide for the escape of sea turtles. TEDs currently approved by NMFS include single-grid hard TEDs and hooped hard TEDs conforming to a generic description, the flounder TED, and one type of soft TED the Parker soft TED (see 50 CFR 223.207).
TEDs incorporate an escape opening, usually covered by a webbing flap, that allows sea turtles to escape from trawl nets. To be approved by NMFS, a TED design must be shown to be 97 percent effective in excluding sea turtles during testing based upon specific testing protocols (50 CFR 223.207(e)(1)). Most approved hard TEDs are described in the regulations (50 CFR 223.207(a)) according to generic criteria based upon certain parameters of TED design, configuration, and installation, including height and width dimensions of the TED opening through which the turtles escape.
February 21, 2003, Amendments to the Sea Turtle Conservation Regulations
On February 21, 2003, NMFS issued a final rule (68 FR 8456), amending the sea turtle conservation regulations to protect large loggerhead, green, and leatherback sea turtles. The February 2003 final rule requires that all shrimp trawlers fishing in the offshore waters of the southeastern United States (Atlantic area and Gulf area) and the inshore waters of Georgia and South Carolina use either a specified double cover flap TED, a single-grid hard TED with a 71-inch (180-cm) opening, or a Parker soft TED with a 96-inch (244-cm) opening in each net rigged for fishing. In inshore waters, except those of Georgia and South Carolina, the rule allows the use of a single-grid hard TED with a 44-inch (112-cm) opening, a Parker soft TED with a 56-inch (142-cm) opening, and a hooped hard TED with a 35-inch (89-cm) by 27-inch (69-cm) escape opening.
Since publication of the final rule, fishermen have reported that the current double cover flap TED design stretches over time. This stretching causes a gap between the flap panels and the grid frame. Fishermen report that this stretching causes loss of shrimp catch. While this loss is unsubstantiated and unquantified, fishermen sought the ability to modify the double cover flap TED design to allow longer flap panels and longer edge lines. Fishermen have concluded that this modification allows retention of shrimp catch.
Accordingly, since September 2003, NMFS has issued 230 experimental permits, in accordance with § 223.207(e)(2), to fishermen to test a modified double cover flap TED with longer flap panels. This modification to the double cover flap TED was designed by NMFS gear technicians in cooperation with industry. The modification incorporates the use of flap panels that extend 24 inches (61 cm) past the posterior edge of the TED frame and are sewn down the entire length of the outside edge of each flap panel. The current double cover flap TED design only allows the flap panels to extend 6 inches (15 cm) past the posterior edge of the TED frame. Interviews with permitted fishermen have indicated that the new design works well in retaining shrimp catch.
Long Flap Paneled Double Cover Flap TED Testing
NMFS tested the modified double cover flap TED using testing protocols designed to evaluate a TED's ability to release large turtles. The protocols were developed during the testing and approval of the double cover flap TED (66 FR 24287, May 14, 2001). NMFS used the average carapace measurements of 15 nesting female leatherback turtles to construct a pipe-framed model of a leatherback turtle. This model measured 40 inches wide by 21 inches (102 cm by 53 cm) deep. The test was performed by a diver swimming repeatedly through the trawl with the model and pushing it through the TED opening. During these tests, the diver was able to push the model through the opening with ease. When the model was inverted (simulating the dorsal surface of the turtle oriented against the TED frame), the diver was still able to push Start Printed Page 31036the model through the opening with ease.
The long flap double cover flap TED was also tested for its ability to release wild turtles of a range of sizes using a modified version of the Cape Canaveral testing protocol published in the Federal Register on October 9, 1990, (55 FR 41092). The 1990 protocol called for the use of a series of double rigged tows, in an area with a high sea turtle concentration (such as the Cape Canaveral Shipping Channel), in which one trawl is a naked net (no TED) and the other includes the experimental TED. The catch of turtles in the naked net is compared to the captures in the net with the TED installed to determine if the TED was at least 97 percent effective at releasing turtles as required by § 223.207(e)(1). NMFS has modified this protocol to better protect turtles and to increase its accuracy. The modifications include the use of two trawls, each rigged with the experimental TED and a video camera mounted by the TED escape opening that can be monitored on board the research vessel. Once the NMFS technician on board the research vessel sees a turtle encounter the TED, the turtle is given 10 minutes to escape. If the turtle does not escape within 10 minutes, the trawl is retrieved and the turtle is released. Any turtle that does not escape within 10 minutes is considered to have been captured.
Using this modified Cape Canaveral protocol, NMFS tested the modified double cover flap TED off the coast of Georgia between November 13 and November 18, 2003, and in the Cape Canaveral Channel between February 19 through March 12, 2004. In total, 33 turtles were exposed to this TED with 32 of the turtles escaping within the 10-minute exposure period for a 97-percent success rate. The turtles exposed to the modified double cover flap TED included one leatherback, seven Kemp's ridleys, and 25 loggerheads. The single turtle that did not escape within the 10-minute limit was a juvenile loggerhead.
Therefore, on April 16, 2004, NMFS published a proposed rule (69 FR 20571) requesting comments on allowing the use of a long flap double cover flap TED in the Atlantic and Gulf of Mexico. No responsive comments were received on the proposed rule.
Provisions of the Final Rule
This final rule will allow the use of a double cover flap TED with flap panels that extend between 6 inches (15 cm) but no more than 24 inches (61 cm) past the posterior edge of the grid with the use of edge lines in all areas and at all times where and when TEDs are required. This final rule will only modify the existing requirements for the double cover flap TED in a permissive manner, i.e., fishermen may now use longer flaps and edge lines on double cover flap TEDs, but if they choose not to make this modification, they are not required to change existing gear.
Specifically, this final rule allows a single-grid hard TED with the escape opening cut of at least 56 inches (142 cm) wide and 20 inches (51 cm) forward and aft, covered with a split flap composed of two equal size rectangular panels. Each panel must be no less than 58 inches (147 cm) wide and may overlap each other no more than 15 inches (38 cm). The panels may only be sewn together along the leading edge of the cut. The edge of the panels may extend no more than 24 inches (61 cm) past the posterior edge of grid, and may be sewn down the entire length of the outside edge of each flap panel. To better preserve the shape of the webbing panels over time, edge lines can be used around the edges of the unattached portion of the flap panels to help maintain the shape of the flap. Edge lines can only be used if the flap panels are sewn down the entire length of the outside edge of each flap panel.
This final rule has been determined to be not significant for purposes of Executive Order 12866.
NMFS prepared an environmental assessment/Regulatory Flexibility Act analysis/regulatory impact review (EA/RFA/RIR) for this final rule that evaluates the potential impact on the environment that may result from the final rule. The EA/RFA/RIR found that the implementation of this rule will not have a significant impact on the quality of the human environment and that the preparation of an environmental impact statement is not necessary.
The final rule is not expected to result in any direct adverse economic impacts on small entities. However, an RFA was conducted. Based on a compilation of data from the shrimp landings file for the Gulf, Florida trip ticket data, and data from the Georgia shrimp landings system, the maximum known gross revenue for an individual fishing craft in the Gulf and South Atlantic shrimp fisheries in 1999 was approximately $724,000 in nominal dollars. While this figure could be an underestimate of the true maximum value since currently available data does not allow all shrimp landings from different parts of the region and their associated revenues to be linked to a particular fishing craft, this figure is sufficiently less than $3.5 million, supporting the presumption that all firms in the Gulf and South Atlantic shrimp trawl fisheries are small business entities.
It is estimated that 11,244 small vessels (vessels less than or equal to 60 ft (18.3 m)) and 2,368 large vessels (vessels greater than 60 ft (18.3 m)), or a total of 13,572 vessels, operate in the Southeast shrimp fishery. Among these vessels, approximately 2,600 vessels are currently permitted to operate in the Gulf of Mexico EEZ commercial shrimp trawl fishery. Small vessels in the Southeast shrimp trawl fishery are estimated to harvest an average of 4,752 pounds of shrimp valued at $12,435 in gross revenues, requiring average variable cost expenditures of $8,708 and generating a profit of $3,727. Large vessels in the Southeast shrimp trawl fishery are estimated to harvest an average of 42,656 pounds of shrimp valued at $142,880 in gross revenues, requiring average variable cost expenditures of $126,089 and generating a profit of $16,089. All participants in the trawl fishery would be affected by the proposed action in that each would have the opportunity to utilize proposed gear modification. However, the preferred alternative does not impose a requirement to use the longer flaps, nor would the use of double-cover TEDs rather than other certified TED designs be required. The final rule, therefore, creates options without additional obligations. Use of the modified TED will require no special skills other than those currently necessary to operate in the fishery. No duplicative, overlapping, or conflicting federal rules have been identified. All business entities participating in the commercial shrimp fisheries are considered small entities, so the issue of disproportionality does not arise. The final rule will not impose any additional fishing restrictions on participants in the fishery. The final rule would simply allow greater flexibility to select the gear configuration that best suits the operational conditions of the individual shrimping operation. Thus, current operational behaviors, including when to shrimp, where to shrimp, and how long to shrimp, as well as where product is marketed, can continue unchanged. Minor costs (approximately $2.00 per vessel) associated with additional netting necessary to extend the flaps may be incurred. However, these costs should not impact profitability and, in fact, would only be incurred should the operator determine that the current flap dimensions result in excessive shrimp loss, such that modification would result in a net Start Printed Page 31037financial gain. Thus, no reduction in profits are expected for any small entities.
Adoption of the no action alternative (not allowing the use of the long flap double cover flap TED) would result in the fishermen's continued reports, but unsubstantiated and unquantified, loss of shrimp resulting from flap stretching over time as the double-cover TEDs are used. Thus, adoption of this no-action alternative will result in the continuation of an unanticipated adverse consequence of the original TED specifications. Although the amount of current shrimp loss as a result of this problem, and the subsequent impacts on revenues and profitability, are unknown, any perceived unnecessary adverse impacts on the economic performance of participants in the fishery further erodes the viability of continued participation, jeopardizing both the shrimping businesses themselves as well as associated industries.
A copy of the EA/RFA/RIR is available from NMFS (see ADDRESSES).
The Assistant Administrator for Fisheries, NOAA, (AA) waives the 30-day delay in effectiveness of this final rule because this rule relieves an existing restriction, and for other good cause. Under the existing TED regulations fishermen can choose to use a single grid hard TED with a 44-inch opening (112- cm)(inshore only), a 71-inch (180-cm) opening, or a double cover flap with a 6-inch (15.3-cm) flap, or they can use the inshore or offshore hooped hard TEDs or the Parker soft TED. Until this final rule becomes effective, long flap double cover flap TED use would not be legal in the southeast shrimp trawl fishery. This rule relieves this restriction for all fishermen in the southeast shrimp trawl fishery. In addition, there are 230 fishermen who have permits to use the long flap double cover flap TED, these permits expire on May 31, 2004. Responses from these fishermen indicate that shrimp loss is low with this TED and they would like to continue to use it. Accordingly, if the effectiveness of this rule is delayed, these permits will expire and the fishermen who are currently using this TED and plan to continue using it will be forced either to abstain from fishing until the rule becomes effective, or else modify their TEDs to meet the current requirements and then modify them back when the rule becomes effective a short time later. Waiver of the 30 day delay in effectiveness will save the fishermen the time and expense of making this change for a limited time only. Therefore, the AA waives the 30 day delay in effectiveness for this final rule.
