Project Narrative – Long Island Oyster Company Parcel # 79005000125, NWS-2009-01350 July 2021 1.0 INTRODUCTION We are submitting this project narrative on behalf of James Kemmer and Andrea Randall of Long Island Oyster Company in conjunction with application materials for coverage under Section 401 of the Clean Waters Act. This application is for continued shellfish aquaculture and harvest activities in Willapa Bay and is consistent with previous permit NWS-2009-1350. The purpose of this project is to continue commercial shellfish aquaculture on an existing farm to sell for human consumption. The proposed project is an existing shellfish aquaculture farm on private tidelands in Pacific County, WA. The project area includes the shellfish growing areas within Parcel #79005000125, described as those tidal elevations between +2.0-foot and +3.0-feet above Mean Lower Low Water. This parcel comprises 55.93 acres, with 55.0 acres of shellfish cultivation. Long Island Oyster Company proposes to continue their production of Pacific oyster (Crassostrea gigas) and Manila clam (Venerupis philippinarum). Additionally, secondary crops from natural set occur across cultivated areas of the Project area. 2.0 CULTURE METHODS 2.1 Pacific Oyster Culture On-Bottom culture methods Oysters (Pacific oysters) are grown directly on the beach substrate. Prior to planting, shellfish beds will be prepared by removing debris by hand. Seeding will occur by using oyster cultch – setting out and securing bags of washed, aged oyster shell to collect natural set on-site. This site will also be seeded with hatchery oyster seed. Harvest methods (mechanical and hand) Harvest typically by hand during low tide. During hand harvest, workers use hand tools or hand-pick oysters and place them into various sized containers placed on the bed. Larger containers may be equipped with ropes and buoys that can be lifted with a boom crane onto the 146 N Canal St, Suite 111 • Seattle, WA 98103 • www.confenv.com July 2021 Project Narrative: Continued Shellfish Aquaculture Operations for Long Island Oyster Company deck of a barge at high tide. Smaller containers are placed or dumped on decks of scows for retrieval at high tide or are carried off the beach at low tide. Mechanical (dredge) harvest occurs by use of a harvest bag that is lowered from a barge or boat by boom crane or hydraulic winch at high tide and pulled along the bottom to scoop up or 'dredge' the oysters. The dredge bags have a leading edge (blade) consisting of a steel frame with teeth and a steel mesh collection bag attached to the frame. As the dredge bags are towed across the substrate, the oysters are loosened and guided into the bags. The bag is then hoisted onto the boat deck, emptied, and then redeployed. Two dredge bags may be towed simultaneously off each side of the boat. Dredge equipment can typically be adjusted so that the correct depth is dredged as tide levels change. Harrowing may occur between the two successive dredge events in order to increase recovery of oysters. 2.2 Manila Clam Culture On-Bottom culture methods Hatchery-grown clams are seeded by hand directly onto the beach substrate. Natural spawning and setting of clams will also occur. Harvest methods (hand harvest) Hand harvesters dig clams during low tides using a clam rake. Shovels or other hand operated tools may also be used. Market-size clams are selectively harvested, placed in buckets, bagged, tagged, and removed. Undersized clams are returned to beds for future harvests. Since a given clam bed may contain multiple year classes of clams, it may be harvested on a regular schedule to harvest individual year classes of clams. www.confenv.com page 2 of 2 Leadbetter Point State Park Bay Center 79005000125 Oysterville Willapa 79005000222 Bay 79005002238 79003000166 Pacific Ocean 79003000175 Nemah 12112723042 79003000175 79003000174 Long Island 79004006026 11101655509 Project: Existing Shellfish Farm Project Parcel Applicant: Long Island Oyster Company Coordinate System: WA State Plane S (ft) Eelgrass/SAV (2015) ¯ 1:170,000 0 1 2 Miles Vicinity Map Exhibit: 1 Long Island Oyster Co.

  • Morphological Variations of the Shell of the Bivalve Lucina Pectinata
    I S S N 2 3 47-6 8 9 3 Volume 10 Number2 Journal of Advances in Biology Morphological variations of the shell of the bivalve Lucina pectinata (Gmelin, 1791) Emma MODESTIN PhD of Biogeography, zoology and Ecology University of the French Antilles, UMR AREA DEV ABSTRACT In Martinique, the species Lucina pectinata (Gmelin, 1791) is called "mud clam, white clam or mangrove clam" by bivalve fishermen depending on the harvesting environment. Indeed, the individuals collected have differences as regards the shape and colour of the shell. The hypothesis is that the shape of the shell of L. pectinata (P. pectinatus) shows significant variations from one population to another. This paper intends to verify this hypothesis by means of a simple morphometric study. The comparison of the shape of the shell of individuals from different populations was done based on samples taken at four different sites. The standard measurements (length (L), width or thickness (E - épaisseur) and height (H)) were taken and the morphometric indices (L/H; L/E; E/H) were established. These indices of shape differ significantly among the various populations. This intraspecific polymorphism of the shape of the shell of P. pectinatus could be related to the nature of the sediment (granulometry, density, hardness) and/or the predation. The shells are significantly more elongated in a loose muddy sediment than in a hard muddy sediment or one rich in clay. They are significantly more convex in brackish environments and this is probably due to the presence of more specialised predators or of more muddy sediments. Keywords Lucina pectinata, bivalve, polymorphism of shape of shell, ecology, mangrove swamp, French Antilles.

Greiner A Swinomish Indian Tribal Community Contribution SWIN-CR-2017-01 September 2017 La Conner, WA 98257 Investigating the collective effect of two ocean acidification adaptation strategies on juvenile clams (Venerupis philippinarum) Courtney M. Greiner A thesis submitted in partial fulfillment of the requirements for the degree of Master of Marine Affairs University of Washington 2017 Committee: Terrie Klinger Jennifer Ruesink Program Authorized to Offer Degree: School of Marine and Environmental Affairs ©Copyright 2017 Courtney M. Greiner University of Washington Abstract Investigating the collective effect of two ocean acidification adaptation strategies on juvenile clams (Venerupis philippinarum) Courtney M. Greiner Chair of Supervisory Committee: Dr. Terrie Klinger School of Marine and Environmental Affairs Anthropogenic CO2 emissions have altered Earth’s climate system at an unprecedented rate, causing global climate change and ocean acidification. Surface ocean pH has increased by 26% since the industrial era and is predicted to increase another 100% by 2100. Additional stress from abrupt changes in carbonate chemistry in conjunction with other natural and anthropogenic impacts may push populations over critical thresholds. Bivalves are particularly vulnerable to the impacts of acidification during early life-history stages. Two substrate additives, shell hash and macrophytes, have been proposed as potential ocean acidification adaptation strategies for bivalves but there is limited research into their effectiveness. This study uses a split plot design to examine four different combinations of the two substratum treatments on juvenile Venerupis philippinarum settlement, survival, and growth and on local water chemistry at Fidalgo Bay and Skokomish Delta, Washington.

  • Functional Traits of a Native and an Invasive Clam of the Genus Ruditapes Occurring in Sympatry in a Coastal Lagoon
    www.nature.com/scientificreports OPEN Functional traits of a native and an invasive clam of the genus Ruditapes occurring in sympatry Received: 19 June 2018 Accepted: 8 October 2018 in a coastal lagoon Published: xx xx xxxx Marta Lobão Lopes1, Joana Patrício Rodrigues1, Daniel Crespo2, Marina Dolbeth1,3, Ricardo Calado1 & Ana Isabel Lillebø1 The main objective of this study was to evaluate the functional traits regarding bioturbation activity and its infuence in the nutrient cycling of the native clam species Ruditapes decussatus and the invasive species Ruditapes philippinarum in Ria de Aveiro lagoon. Presently, these species live in sympatry and the impact of the invasive species was evaluated under controlled microcosmos setting, through combined/manipulated ratios of both species, including monospecifc scenarios and a control without bivalves. Bioturbation intensity was measured by maximum, median and mean mix depth of particle redistribution, as well as by Surface Boundary Roughness (SBR), using time-lapse fuorescent sediment profle imaging (f-SPI) analysis, through the use of luminophores. Water nutrient concentrations (NH4- N, NOx-N and PO4-P) were also evaluated. This study showed that there were no signifcant diferences in the maximum, median and mean mix depth of particle redistribution, SBR and water nutrient concentrations between the diferent ratios of clam species tested. Signifcant diferences were only recorded between the control treatment (no bivalves) and those with bivalves. Thus, according to the present work, in a scenario of potential replacement of the native species by the invasive species, no signifcant diferences are anticipated in short- and long-term regarding the tested functional traits.

Aquaculturists around the world have developed a variety of different clam farming systems, notably for the Manila clam, Venerupis philippinarum (Adams & Reeve, 1850). 2 - The aim was to test the aquaculture of V. decussata using the FLoating UPwelling SYstem (FLUPSY) to evaluate their growth rate over two seasons: spring 2011 (from 10 March, 2011, to 21 May, 2011), and autumn 2011 (from 18 October, 2011, to 28 December, 2011). The study was carried out in the Tortolì coastal lagoon, Eastern Sardinia (Italy; latitude 39°56’ N, longitude 9°41’ E). 3 - V. decussata juveniles with mean shell lengths of 10.88±0.91 mm in spring and 8.95 ± 0.75 mm in autumn, mean shell thicknesses of 5.21±0.54 mm in spring and 3.36 ± 0.27 mm in autumn, and mean total weight of 0.33±0.09 g in spring and 0.1 2± 0.03 g in autumn, were bred following FLUPSY.

Interactions with the native species include hybridization with the grooved carpet-shell Ruditapes philippinarum (GCS) clam (R. decussatus), which may have both useful and undesirable consequences. Here we report an Hybridization attempt to produce hybrids in captivity by crossing 3 females and 4–5 males of each species in a two-step Growth protocol that favored hybrid fertilizations. One-hundred animals were sampled at 15 months after fertiliza­ tion, and scored for one morphological diagnostic trait (siphon fusion) and two diagnostic genetic DNA markers (ITS-2 and Fas-i1). No hybrids were detected, although the 0% hybridization rate has an associated 95% con­ fidence interval of 3.3%.

  • Marine Reserves Enhance Abundance but Not Competitive Impacts of a Harvested Nonindigenous Species
    Ecology, 86(2), 2005, pp. 487–500 ᭧ 2005 by the Ecological Society of America MARINE RESERVES ENHANCE ABUNDANCE BUT NOT COMPETITIVE IMPACTS OF A HARVESTED NONINDIGENOUS SPECIES JAMES E. BYERS1 Friday Harbor Laboratories, University of Washington, 620 University Road, Friday Harbor, Washington 98250 USA Abstract. Marine reserves are being increasingly used to protect exploited marine species. However, blanket protection of species within a reserve may shelter nonindigenous species that are normally affected by harvesting, intensifying their impacts on native species. I studied a system of marine reserves in the San Juan Islands, Washington, USA, to examine the extent to which marine reserves are invaded by nonindigenous species and the con- sequences of these invasions on native species. I surveyed three reserves and eight non- reserves to quantify the abundance of intertidal suspension-feeding clam species, three of which are regionally widespread nonindigenous species (Nuttallia obscurata, Mya arenaria, and Venerupis philippinarum). Neither total nonindigenous nor native species’ abundance was significantly greater on reserves. However, the most heavily harvested species, V. philippinarum, was significantly more abundant on reserves, with the three reserves ranking highest in Venerupis biomass of all 11 sites. In contrast, a similar, harvested native species (Protothaca staminea) did not differ between reserves and non-reserves. I followed these surveys with a year-long field experiment replicated at six sites (the three reserves and three of the surveyed non-reserve sites). The experiment examined the effects of high Venerupis densities on mortality, growth, and fecundity of the confamilial Protothaca, and whether differences in predator abundance mitigate density-dependent effects. Even at densities 50% higher than measured in the field survey, Venerupis had no direct effect on itself or Protothaca; only site, predator exposure, and their interaction had significant effects.

Such assessments can contribute to a more comprehensive evaluation of natural history museums in the Philippines, as well as biodiversity management. This review showed that local museums in the Philippines have much to improve in terms of their accessibility and geographic coverage in order to effectively cater to research and conservation needs of the country. Online access to databases was lacking for local museums, making it cumbersome to retrieve collection information. The UST museum held the most species and subspecies across all museums (4899), comparable to the national museums of countries such as the USA and France. In terms of size, there were larger Philippine mollusk collections in museums abroad. Majority of mollusk specimens come from Regions 4 and 7, while the CAR and Region 12 were least sampled. Publications on Philippine mollusks are dominated by taxonomic and biodiversity research.
