Argopecten Irradians*
MARINE ECOLOGY PROGRESS SERIES I Vol. 74: 47-59, 1991 Published July 18 Mar. Ecol. Prog. Ser. The eelgrass canopy: an above-bottom refuge from benthic predators for juvenile bay scallops Argopecten irradians* David G.Pohle, V. Monica Bricelj8*,Zaul Garcia-Esquivel Marine Sciences Research Center, State University of New York, Stony Brook, New York 11794-5000, USA ABSTRACT: Juvenile bay scallops Argopecten irradians commonly attach to shoots of eelgrass Zostera marina using byssal threads. Although this behavior has long been recognized, its adaptive value is poorly understood. This study examined (1) the size-specif~cnature of scallop attachment on eelgrass, and (2) the possible role of vertical attachment in providing refuge from benthic predators. Laboratory experiments using artificial eelgrass showed strong, inverse relationships between scallop size (over the range 6 to 20 mm) and several measures of attachment performance (percent attachment, rate of attachment, and height-above-bottom attained). Field experiments in which 10 to 15 mm scallops were tethered to natural eelgrass in Lake Montauk, Long Island, New York (USA), demonstrated a dramatic, highly significant enhancement of scallop survival at greater heights of attachment. Scallops tethered at 20 to 35 cm above bottom experienced > 59 O/O survival over 4 d, compared to < l1 O/O sunrival near the sediment surface. A similar pattern was observed in laboratory tethering experiments using trans- planted natural eelgrass and 3 crab predators common in mid-Atlantic embayments: Carcinus maenas, Libinia dubia, and Dyspanopeus sayi. The refuge value of vertical attachment was found, however, to be less with D. sayi than with the other predators tested, since individuals of ths species climbed eelgrass to feed on scallops in the upper canopy. -

Vol. 23: 265–274, 2015 AQUATIC BIOLOGY Published online April 1 doi: 10.3354/ab00626 Aquat Biol OPENPEN ACCESSCCESS Reproduction reduces HSP70 expression capacity in Argopecten purpuratus scallops subject to hypoxia and heat stress Katherina Brokordt*, Hernán Pérez, Catalina Herrera, Alvaro Gallardo Centro de Estudios Avanzados en Zonas Áridas (CEAZA), Universidad Católica del Norte, Larrondo 1281, Coquimbo, Chile ABSTRACT: In scallops, gonad production is highly demanding energetically, and reproduction usually occurs during spring−summer, a period of strong environmental changes. The synthesis of heat-shock proteins (HSPs) is a major mechanism of stress tolerance in animals, including scal- lops, and HSP expression contributes considerably to cellular energy demand. Therefore, repro- ductive investment may limit the availability of energy (in terms of ATP) for the expression of HSP in organisms exposed to environmental stress. We evaluated the stress response capacity of adult Argopecten purpuratus scallops to high temperature and hypoxia. Stress response capacity was assessed through gene expression (for temperature stress) and protein induction of 70 kD HSP at 3 reproductive stages: immature, mature and spawned. We also evaluated the effect of reproduc- tive status on the cellular ATP provisioning capacity through citrate synthase activity. Immature scallops exposed to thermal stress showed 1.3- and 1.5-fold increases in hsp70 mRNA and HSP70 protein levels, respectively, and those exposed to hypoxia doubled their level of HSP70 compared to non-stressed immature scallops. However, following gonad maturation and spawning, hsp70 mRNA increased by only 0.49- and 0.65-fold, respectively, after thermal stress and HSP70 protein levels of scallops exposed to thermal and hypoxia stressors did not differ from those of non- stressed animals. -
<I>Aplysia Californica</I>
Temperature Eff ects on Growth, Maturation, and Lifes- pan of the California Sea Hare (Aplysia californica) DUSTIN STOMMES, BLA, LYNNE A. FIEBER, PHD,* CHRISTINA BENO, ROBERT GERDES, MS, and THOMAS R. CAPO, BS We conducted a hatchery growth study to describe the variability in growth rates, spawning, and mortality of Aplysia californica in regard to rearing temperature. Animals were housed at a standard hatchery density of fi ve animals per cage, at temperatures of 13, 15, 18, and 21°C. Animals reared at 13 or 15°C grew as much as four times as large, lived twice as long, matured later, and spawned longer than did animals reared at 18 or 21°C. At age 170 to 205 days the fastest growth rates occurred at 18 and 21°C, and the slowest at 13°C. As animals at 18 and 21°C reached sexual maturity at ages 190 to 197 days, or ∼60% through their lifespans, their growth rates slowed such that by age 260 days, the fastest growth rate was at 13°C, and the slowest was at 21°C. Animals reared at 13 and 15°C reached sexual maturity at 242 and 208 days, respectively, or at ∼40% of their life spans. Lifespan and maximum average animal weight were signifi cantly inversely correlated with temperature (P ≤ 0.0001). However, there were no signifi cant diff erences at any temperature in the age at which maximum animal weight was reached when this age was expressed as a percentage of the life span: animals reached their maximum weight at ∼80% of their life span. -
Physiological Effects and Biotransformation of Paralytic
PHYSIOLOGICAL EFFECTS AND BIOTRANSFORMATION OF PARALYTIC SHELLFISH TOXINS IN NEW ZEALAND MARINE BIVALVES ______________________________________________________________ A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy in Environmental Sciences in the University of Canterbury by Andrea M. Contreras 2010 Abstract Although there are no authenticated records of human illness due to PSP in New Zealand, nationwide phytoplankton and shellfish toxicity monitoring programmes have revealed that the incidence of PSP contamination and the occurrence of the toxic Alexandrium species are more common than previously realised (Mackenzie et al., 2004). A full understanding of the mechanism of uptake, accumulation and toxin dynamics of bivalves feeding on toxic algae is fundamental for improving future regulations in the shellfish toxicity monitoring program across the country. This thesis examines the effects of toxic dinoflagellates and PSP toxins on the physiology and behaviour of bivalve molluscs. This focus arose because these aspects have not been widely studied before in New Zealand. The basic hypothesis tested was that bivalve molluscs differ in their ability to metabolise PSP toxins produced by Alexandrium tamarense and are able to transform toxins and may have special mechanisms to avoid toxin uptake. To test this hypothesis, different physiological/behavioural experiments and quantification of PSP toxins in bivalves tissues were carried out on mussels ( Perna canaliculus ), clams ( Paphies donacina and Dosinia anus ), scallops ( Pecten novaezelandiae ) and oysters ( Ostrea chilensis ) from the South Island of New Zealand. Measurements of clearance rate were used to test the sensitivity of the bivalves to PSP toxins. Other studies that involved intoxication and detoxification periods were carried out on three species of bivalves ( P. -

Furthermore, several 16S rDNA deep amplicon sequencing studies support a fundamental role of the microbiota on the host health and homeostasis. In this context, the aim Host-microbiota interactions of this work was to determine the structure and diversity of the microbiota associated with the scallop Argopecten Scallop purpuratus, and to assess changes in community composition and diversity during the host immune response. To Innate immune response do this, adult scallops were immune challenged and sampled after 24 and 48 h. Activation of the immune Antimicrobial effectors response was established by transcript overexpression of several scallop immune response genes in hemocytes and gills, and confirmed by protein detection of the antimicrobial peptide big defensin in gills of Vibrio-injected scallops at 24 h post-challenge. -

This work is the first study to research the embryology and larval development of this species of razor clam, using light and scanning electron microscopy. A new method, consisting of changing water levels using tide simulations with brief Downloaded from https://academic.oup.com/mollus/article/74/2/103/1161011 by guest on 23 September 2021 dry periods, was developed to induce spawning in this species. The blastula was the first motile stage and in the gastrula stage the vitelline coat was lost. The shell field appeared in the late gastrula. The trocho- phore developed by about 19 h post-fertilization (hpf) (198C). At 30 hpf the D-shaped larva showed a developed digestive system consisting of a mouth, a foregut, a digestive gland followed by an intestine and an anus. Larvae spontaneously settled after 20 days at a length of 378 mm.

Shelled Molluscs

They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric tons landed worldwide in 1996. Aquaculture, which mainly concerns bivalves (oysters, scallops, and mussels) relies on the simple techniques of producing juveniles, natural spat collection, and hatchery, and the fact that many species are planktivores.

Fieber* Although the California sea hare, Aplysia californica, is well known from neurobiological studies and is raised in the laboratory for this purpose, various aspects of its life history in the laboratory, such as aging dynamics, are unknown. There- fore we collected life history data on 4 cohorts of eggs from hatchery-reared animals and performed an actuarial analysis of mortality data. Temperature was controlled at 13 to 15 °C, the photoperiod was a 14:10-h light:dark cycle, and the seawater O2 concentration, pH, and salinity were held at optimized levels. The feeding protocol for 3 cohorts was unrestricted access to the red macroalga Gracilaria ferox, whereas the remaining cohort was fed standard hatchery rations of G. ferox 4 times per week. Growth was sigmoidal in each cohort and resulted in linear growth rates of 1.25 to 3.62 g/d during the exponential phase; these rates were not influenced by feeding level. Sexual maturity occurred at approximately 160 g, at ages ranging from 144 to 241 d. Egg production was highly variable in the different cohorts. Mean lifespan of cohorts fed ad libitum was approximately 228 d. In contrast, the cohort fed standard rations lived an average of 375 d and showed a lower initial mortality rate, suggesting that calorie restriction on a single-species diet prolongs lifespan in California sea hares. -
An Adipokinetic Hormone Acts As a Volume Regulator in the Intertidal Gastropod Mollusk, Aplysia Californica
ORIGINAL RESEARCH published: 24 August 2018 doi: 10.3389/fendo.2018.00493 An Adipokinetic Hormone Acts as a Volume Regulator in the Intertidal Gastropod Mollusk, Aplysia californica Anthony W. Martillotti and Pei-San Tsai* Department of Integrative Physiology, University of Colorado, Boulder, CO, United States Adipokinetic hormone (AKH) is a multifunctional neuropeptide in the gonadotropin-releasing hormone superfamily. In insects, AKH acts to mobilize energy stores during times of high energetic demand, but has been shown to have other effects. In lophotrochozoans, the presence and function of AKH are less characterized. We have previously identified an AKH in an intertidal gastropod mollusk, the California sea hare (Aplysia californica), and named it ac-AKH. Our previous data showed ac-AKH induced an acute weight loss, suggesting a role in volume regulation. The overarching goals of this study were to test the role of ac-AKH as a volume regulator and examine the mechanism by which ac-AKH induced the acute weight loss. Our results showed that ac-AKH Edited by: reduced body mass, in part, through the reduction of hemolymph volume without Honoo Satake, Suntory Foundation for Life Sciences, altering hemolymph osmolality or specific osmolytes. The effect of ac-AKH on volume Japan loss was accentuated under a hyposaline condition. We further showed that ac-akh Reviewed by: expression was inhibited during a hyposaline challenge, and that the administration of Fumihiro Morishita, ac-AKH partially reversed the increase in body mass, but not hemolymph osmolality Hiroshima University, Japan Makoto Osada, change, caused by the hyposaline challenge. These data collectively show that ac-AKH Tohoku University, Japan is a proximate regulator controlling the fluid volume, but not osmolality, in A.
