Essential Fish Habitat (EFH) is managed under the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), which is designed to protect waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity. This EFH Assessment was prepared pursuant to the Magnuson-Stevens Act to analyze potential impacts to federally managed fish and invertebrates from construction and operation of the proposed Project. The primary Project elements that could affect the marine environment, including EFH, include: . Dredging (including installation of king piles and approximately 1,400 linear feet of sheet piling to stabilize the wharf) at Berths 226-229 to a design depth of -53 feet mean lower low water (MLLW) plus two feet of overdepth tolerance (for a total depth of -55 feet MLLW) to accommodate larger ships (the existing design depth is -45 feet MLLW); . Dredging (including installation of approximately 1,400 linear feet of sheet piling to stabilize the wharf) at Berths 230-232 to a design depth of -47 feet MLLW plus two feet of overdepth tolerance (for a total depth of -49 feet MLLW) to accommodate larger ships (the existing design depth is -45 feet MLLW); . Disposal of approximately 38,000 cubic yards of dredged materials (30,000 cubic yards from Berths 226-229 and 8,000 cubic yards from Berths 230-232) at an ocean disposal site (i.e., LA-2), assuming an approved upland disposal facility, or a combination

Caesio cuning is a reef-associated artisanal fishery, making it an ideal species for assessing regional patterns of gene flow for evidence of speciation mechanisms as well as for regional management purposes. We evaluated the genetic population structure of Caesio cuning using a 382bp segment of the mitochondrial control region amplified from over 620 fish sampled from 33 localities across the Philippines and Indonesia.
