    Journal of Aquaculture & Marine Biology Research Article Open Access Diversity and life-cycle analysis of Pacific Ocean zooplankton by video microscopy and DNA barcoding: Crustacea Abstract Volume 10 Issue 3 - 2021 Determining the DNA sequencing of a small element in the mitochondrial DNA (DNA Peter Bryant,1 Timothy Arehart2 barcoding) makes it possible to easily identify individuals of different larval stages of 1Department of Developmental and Cell Biology, University of marine crustaceans without the need for laboratory rearing. It can also be used to construct California, USA taxonomic trees, although it is not yet clear to what extent this barcode-based taxonomy 2Crystal Cove Conservancy, Newport Coast, CA, USA reflects more traditional morphological or molecular taxonomy. Collections of zooplankton were made using conventional plankton nets in Newport Bay and the Pacific Ocean near Correspondence: Peter Bryant, Department of Newport Beach, California (Lat. 33.628342, Long. -117.927933) between May 2013 and Developmental and Cell Biology, University of California, USA, January 2020, and individual crustacean specimens were documented by video microscopy. Email Adult crustaceans were collected from solid substrates in the same areas. Specimens were preserved in ethanol and sent to the Canadian Centre for DNA Barcoding at the Received: June 03, 2021 | Published: July 26, 2021 University of Guelph, Ontario, Canada for sequencing of the COI DNA barcode. From 1042 specimens, 544 COI sequences were obtained falling into 199 Barcode Identification Numbers (BINs), of which 76 correspond to recognized species. For 15 species of decapods (Loxorhynchus grandis, Pelia tumida, Pugettia dalli, Metacarcinus anthonyi, Metacarcinus gracilis, Pachygrapsus crassipes, Pleuroncodes planipes, Lophopanopeus sp., Pinnixa franciscana, Pinnixa tubicola, Pagurus longicarpus, Petrolisthes cabrilloi, Portunus xantusii, Hemigrapsus oregonensis, Heptacarpus brevirostris), DNA barcoding allowed the matching of different life-cycle stages (zoea, megalops, adult).

  • 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.
