Culture Protocols and Production of Triploid Purple-Hinge Rock Scallops
水 研 機 構 研 報, 第 45 号,29 - 31, 平 成 29 年 Bull. Jap. Fish. Res. Edu. Agen. No. 45,29-31,2017 29 Culture Protocols and Production of Triploid Purple-Hinge Rock Scallops Paul G. OLIN* Abstract: The goal of this ongoing research and outreach is to expand the West Coast shellfish industry through creation of triploid seed and demonstration of efficient culture methods for the native purple-hinge rock scallop (Crassadoma gigantea). Shellfish aquaculture is a low trophic level means of seafood production that provides many benefits to coastal communities and the environment, while at the same time increasing the supply of locally produced safe and nutritious seafood. There is a strong desire to develop native species for aquaculture development to diversify the shellfish industry and help to avoid concerns often voiced today about the use of non-native species. While new native species of shellfish for aquaculture are highly sought after, there are also genetic concerns associated with rearing native species for aquaculture using hatchery-reared seed that may have undergone significant domestication selection or been produced from distant broodstock populations. This may occur as a normal consequence of rearing in the hatchery environment or through highly directed selection, crossbreeding, or other means to genetically change the production characteristics of the organism. These risks are significant and must be addressed to realize the potential for growth of the U.S. west coast shellfish industry. Issues associated with potential genetic risk to wild rock scallop populations could be resolved through the creation of tetraploid scallop stocks, which could be mated to diploids, producing 100% triploid offspring, or by using chemical means. -

Molluscs: Bivalvia Laura A
I Molluscs: Bivalvia Laura A. Brink The bivalves (also known as lamellibranchs or pelecypods) include such groups as the clams, mussels, scallops, and oysters. The class Bivalvia is one of the largest groups of invertebrates on the Pacific Northwest coast, with well over 150 species encompassing nine orders and 42 families (Table 1).Despite the fact that this class of mollusc is well represented in the Pacific Northwest, the larvae of only a few species have been identified and described in the scientific literature. The larvae of only 15 of the more common bivalves are described in this chapter. Six of these are introductions from the East Coast. There has been quite a bit of work aimed at rearing West Coast bivalve larvae in the lab, but this has lead to few larval descriptions. Reproduction and Development Most marine bivalves, like many marine invertebrates, are broadcast spawners (e.g., Crassostrea gigas, Macoma balthica, and Mya arenaria,); the males expel sperm into the seawater while females expel their eggs (Fig. 1).Fertilization of an egg by a sperm occurs within the water column. In some species, fertilization occurs within the female, with the zygotes then text continues on page 134 Fig. I.

THE EFFECT OF OCTOPUS PREDATION ON A SPONGE-SCALLOP ASSOCIATION Thomas J. Ewing , Kirt L. Onthank and David L. Cowles Walla Walla University Department of Biological Sciences ABSTRACT In the Puget Sound the scallop Chlamys hastata is often found with its valves encrusted with sponges. Scallops have been thought to benefit from this association by protection from sea star predation, but this idea has not been well supported by empirical evidence. Scallops have a highly effective swimming escape response and are rarely found to fall prey to sea stars in the field. Consequently, a clear benefit to the scallop to preserve the relationship is lacking. We propose that octopuses could provide the predation pressure to maintain this relationship. Two condi- tions must first be met for this hypothesis to be supported: 1) Octopuses eat a large quantity of scallops and 2) Octo- puses must be less likely to consume scallops encrusted with sponges than unencrusted scallops. We found that Chlamys hastata may comprise as much as one-third of the diet of giant Pacific octopus (Enteroctopus dofleini) and that E. dofleini is over twice as likely to choose an unencrusted scallop over an encrusted one. While scallops are a smaller portion of the diet of O. rubescens this species is five times as likely to consume scallops without sponge than those with. This provides evidence the octopuses may provide the adaptive pressure that maintains the scallop -sponge symbiosis. INTRODUCTION The two most common species of scallop in the Puget Sound and Salish Sea area of Washington State are Chlamys hastata and Chlamys rubida. -
