UC San Diego Research Theses and Dissertations Title The population dynamics of mitten crab larvae in the San Francisco Bay Permalink https://escholarship.org/uc/item/01g8c0ck Author Gonzales, Vanessa Alexandra Publication Date 2010-10-01 eScholarship.org Powered by the California Digital Library University of California ABSTRACT THE POPULATION DYNAMICS OF MITTEN CRAB LARVAE IN THE SAN FRANCISCO BAY The Chinese mitten crab, Eriocheir sinensis, has a history of invasions in numerous countries. In 1992, the Chinese mitten crab was introduced to the San Francisco Bay/Delta system. Since its invasion in the San Francisco Bay, it has become an aquatic nuisance species. Little is known about the population dynamics of the megalopa stage of the Chinese mitten crab in the San Francisco Bay estuary, particularly the megalopa stage. Light traps are often used to sample marine larvae and can provide measures for relative abundance of larvae between sampling locations. As part of an ongoing study to monitor mitten crab larvae in the San Francisco Bay, light trap and plankton tow samples were analyzed for mitten crab megalopae and zoeae. In order to implement low cost sampling devices for mitten crab megalopae such as light traps, it is necessary to be able to identify their larvae in collected samples. Thus, the main objective of this work was to develop a means to distinguish mitten crab megalopae from other native and invasive brachyuran megalopae inhabiting the San Francisco Bay Estuary. The minimal amount of mitten crab megalopae found in light trap samples may be linked to the recent decline of mitten crab zoeae in San Pablo Bay.

Many invasive species have been introduced to different environments because of human activities. In the past, geographic barriers, such as oceans, deserts, and mountains, made it difficult for species to colonize new habitats. However, the transoceanic movement of humans has helped to facilitate the invasion of many species to novel habitats (Bright, 1999; McNeely, 2006). The consequences of such invasions often are negative (Vitousek et al, 1997; Sanders et al., 2003). Aquatic habitats are among the most invaded environments (Ruiz et al., 1999). This is probably due to commercial shipping, fishing, and recreational activity that occur in these habitats (LeMaitre et al., 2004; McNeely, 2006). Although unsuccessful invasions go unnoticed, aquatic invaders that are successful in establishing populations can have dramatic affects on the structure and function of the ecosystem that they invade (Miehls et al., 2009; Pejchar and Mooney, 2009). Once a nuisance species has been established, control efforts can be extremely costly (Pimetel et al., 2001; Pimetel et al., 2005). Some introduced species can even act as vectors for disease, and thus pose risks to native species and in some cases human populations (Prenter et al., 2004; Cohen, 2003). One aquatic ecosystem that has been heavily invaded is the San Francisco Bay Estuary (Cohen and Carlton, 1998). The Chinese mitten crab, Eriocheir sinensis, is a problematic invader in the San Francisco Bay (Veldhuizen, 1997; Veldhuizen and Stanish, 1999; Rudnick et al.

E-mail: [email protected] Abstract Within the recently resurrected family Inachoididae is Leurocyclus tuberculosus, an inachoidid spider crab distributed throughout the Western Atlantic of South America from Brazil to Argentina (including Patagonia), and along the Eastern Pacific coast of Chile. The larval development of L. tuberculosus consists of two zoeal stages and one megalopa. We observed that the larval morphology of L. tuberculosus conforms to the general pattern found in Majoidea by having two zoeal stages, in which the first stage has nine or more seta on the scaphognatite of the maxilla, and the second zoeal stage present well developed pleopods. Here, we describe the larval morphology of L. tuberculosus and compare with other inachoidid members for which we have larval information.

  • Native Decapoda

    Native Decapoda

    NATIVE DECAPODA Dungeness crab - Metacarcinus magister DESCRIPTION This crab has white-tipped pinchers on the claws, and the top edges and upper pincers are sawtoothed with dozens of teeth along each edge. The last three joints of the last pair of walking legs have a comb-like fringe of hair on the lower edge. Also the tip of the last segment of the tail flap is rounded as compared to the pointed last segment of many other crabs. RANGE Alaska's Aleutian Islands south to Pt Conception in California SIZE Carapace width to 25 cm (9 inches), but typically less than 20 cm STATUS Native; see the full record at http://www.dfg.ca.gov/marine/dungeness_crab.asp COLOR Light reddish brown on the back, with a purplish wash anteriorly in some specimens. Underside whitish to light orange. HABITAT Rock, sand and eelgrass TIDAL HEIGHT Subtidal to offshore SALINITY Normal range 10–32ppt; 15ppt optimum for hatching TEMPERATURE Normally found from 3–19°C SIMILAR SPECIES Unlike the green crab, it has 10 spines on either side of the eye sockets and grows much larger. It can be distinguished from Metacarcinus gracilis which also has white claws, by the carapace being widest at the 10th tooth vs the 9th in M. gracilis . Unlike the red rock crab it has a tooth on the dorsal margin of its white tipped claw (this and other similar Cancer crabs have black tipped claws). ©Aaron Baldwin © bioweb.uwlax.edu red rock crab - note black tipped claws Plate Watch Monitoring Program .

    1 Metagenetic Analysis of 2018 and 2019 Plankton Samples from Prince

    Metagenetic Analysis of 2018 and 2019 Plankton Samples from Prince William Sound, Alaska. Report to Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) From Molecular Ecology Laboratory Moss Landing Marine Laboratory Dr. Jonathan Geller Melinda Wheelock Martin Guo Any opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC. April 13, 2020 ABSTRACT This report describes the methods and findings of the metagenetic analysis of plankton samples from the waters of Prince William Sound (PWS), Alaska, taken in May of 2018 and 2019. The study was done to identify zooplankton, in particular the larvae of benthic non-indigenous species (NIS). Plankton samples, collected by the Prince William Sound Science Center (PWSSC), were analyzed by the Molecular Ecology Laboratory at the Moss Landing Marine Laboratories. The samples were taken from five stations in Port Valdez and nearby in PWS. DNA was extracted from bulk plankton and a portion of the mitochondrial Cytochrome c oxidase subunit 1 gene (the most commonly used DNA barcode for animals) was amplified by polymerase chain reaction (PCR). Products of PCR were sequenced using Illumina reagents and MiSeq instrument. In 2018, 257 operational taxonomic units (OTU; an approximation of biological species) were found and 60 were identified to species. In 2019, 523 OTU were found and 126 were identified to species. Most OTU had no reference sequence and therefore could not be identified. Most identified species were crustaceans and mollusks, and none were non-native. Certain species typical of fouling communities, such as Porifera (sponges) and Bryozoa (moss animals) were scarce. Larvae of many species in these phyla are poorly dispersing, such that they will be found in abundance only in close proximity to adult populations.
