(Received 29 June 2007, Accepted 20 February 2008) A dimensionless measure of otolith mass asymmetry, w, was calculated as the difference between the masses of the right and left paired otoliths divided by average otolith mass. Saccular otolith mass asymmetry was studied in eight flatfish species (110 otolith pairs) and compared with data from a previously published study on roundfishes. As in the case of symmetrical fishes, the absolute value of w in flatfishes does not depend on fish length and otolith growth rate, although otolith mass and the absolute value of otolith mass difference are correlated with fish length. The values of w were between À0Á2 and þ0Á2in96Á4% of flatfishes studied. The mean Æ S.E. value of w in flatfishes was significantly larger than in standard bilaterally symmetrical marine fishes (‘roundfishes’), respectively 0Á070 Æ 0Á006 and 0Á040 Æ 0Á006.

A genetic and morphometric study of populations of Zoogoneticus quitzeoensis (Bean, 1898) from the Lerma and Ameca basins and Cuitzeo, Zacapu and Chapala Lakes in Central Mexico was conducted. For the genetic analysis, 7 populations were sampled and 2 monophyletic groups were identifi ed with a genetic difference of DHKY= 3.4% (3-3.8%), one being the populations from the lower Lerma basin, Ameca and Chapala Lake, and the other populations from Zacapu and Cuitzeo Lakes. For the morphometric analysis, 4 populations were sampled and 2 morphotypes identifi ed, 1 from La Luz Spring in the lower Lerma basin and the other from Zacapu and Cuitzeo Lakes drainages. Using these 2 sources of evidence, the population from La Luz is regarded as a new species Zoogoneticus purhepechus sp. nov. _The new species differs from its sister species Zoogoneticus quitzeoensis_ in having a shorter preorbital distance (Prol/SL x = 0.056, SD = 0.01), longer dorsal fi n base length (DFL/SL x = 0.18, SD = 0.03) and 13-14 rays in the dorsal fi n.

  • A REVISION of the GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT in Addition to Gambusia
    Reprinted from PUBLICATIONS OF THE GULF COAST RESEARCH LABORATORY MUSEUM 2:47-77, June 18, 1971 A REVISION OF THE GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT In addition to Gambusia nicaraguensis, the species group includes G. wrayi, G. mela pleura and G. his paniolae sp. nov. G. gracilior is a junior synonym of G. wrayi and G. dominicensis is found to be a member of another species group. A key and zoogeographical notes are provided for the group. Rivas (1963) published on subgenera and species groups in the genus Gambusia. He used only gonopodial characters in defining his groups, and I believe that his system is both natural and practical. Subsequent investigation has shown a need to review his findings and to make adjust- ments in the system. I have found that G. dominicensis is a member of another species group and that the species referred to as dominicensis by Rivas (1963) is actually undescribed. Otherwise, I accept his G. nicara- guensis species group and feel that its revision will help clarify other prob- lems within the genus. METHODS.—Methods are those of Fink (1971). Abbreviations are as follows: ANSP - Academy of Natural Sciences of Philadelphia; BMNH - British Museum (Natural History); GCRL - Gulf Coast Re- search Laboratory; UMMZ - University of Michigan Museum of Zoology; USNM - United States National Museum.

  • Report on the California Data-Limited Fisheries Project: Integrating MSE Into the Management of California State Fisheries
    Report on the California Data-Limited Fisheries Project: Integrating MSE into the Management of California State Fisheries July 2020 Introduction Over the past five years, California Department of Fish and Wildlife (CDFW) has made a substantial investment of resources in integrating management strategy evaluation (MSE) into the science and management of California state fisheries. The initial phase of the project, beginning in July 2015, used a stakeholder process to demonstrate how MSE could be used to manage data-limited fisheries in the state through the application of the Data-Limited Methods Toolkit (DLMtool). Four fisheries were analyzed as case studies for that phase of the project: Barred Sand Bass, California Halibut, Red Sea Urchin, and Warty Sea Cucumber. This led to the incorporation of MSE into the revised 2018 Master Plan for Fisheries (Master Plan) and laid the groundwork for continued collaboration with CDFW to build the scientific capacity of its staff and to apply MSE to additional fisheries. The current phase of the project, beginning in February 2018, included a series of webinars and workshops with a group of six CDFW biologists and managers to train them in basic fishery population dynamics modeling and the fundamentals of MSE using the DLMtool. The second component of the project involved developing new or updated MSEs for eight fisheries, including the four from the initial phase of the project and the following additional fisheries: Kelp Bass, Rock Crab, Spiny Lobster, and Redtail Surfperch. The eight fisheries were chosen because they represent a range of life histories and data availability. The outputs of these MSEs, which have been submitted to CDFW for review as of the date of this report, will be used to understand the tradeoffs and levels of uncertainty with the current management frameworks for each fishery and how they perform in both the short- and long-term.

INTRODUCTION WildEarth Guardians and Sarah Felsen hereby petition the Secretary of Commerce, acting through the National Marine Fisheries Service (“NMFS”) within the National Oceanic and Atmospheric Administration (“NOAA”), and the Secretary of the Interior, acting through the U.S. Fish and Wildlife Service (“FWS”), to list and thereby protect under the Endangered Species Act (“ESA”),1 the Saltmarsh Topminnow, Fundulus jenkinsi (Evermann, 1892) (hereinafter “Saltmarsh Topminnow” or “Topminnow”).2 Concurrent with its listing, Petitioner seeks the designation of critical habitat for this species throughout its range. The Saltmarsh Topminnow occurs sporadically in fragile marsh habitat along the U.S. coast of the Gulf of Mexico, from Galveston, Texas to Escambia Bay, Florida (Peterson et al. 2003). Specialists in marine science have long considered this fish to be extremely rare. It either occurs in very small populations or is simply absent from the reports of most fish studies of the northern Gulf of Mexico.
