E-mail: [email protected] Abstract: The north coast of the São Paulo State, Brazil, presents great bivalve diversity, but knowledge about these organisms, especially species living subtidally, remains scarce. Based on collections made between 2010 and 2012, the present work provides a species list of bivalves inhabiting the intertidal and subtidal zones of the São Sebastião Channel. Altogether, 388 living specimens were collected, belonging to 52 species of 34 genera, grouped in 18 families. -

Pesquera Complejo Docente El Sabino, Prolongacion Tachira, Sector Universidad, Punto Fijo, Falcon 4102 Venezuela RESUMEN El guacuco, Chione cancellata, es una de las especies de moluscos bivalvos de mayor importancia comercial en la costas de la Bahía de Amuay. La mayoría de los pobladores de la zona, viven de su extracción y comercialización. Hasta el momento no se tienen información sobre el desarrollo larval de esta especie, para ser explotado en un futuro cultivo. Por tal motivo, se realizó la inducción al desove de este molusco, utilizando como técnica el choque térmico y descripción de su desarrollo larval. Se obtuvo con éxito el desove después de tres horas de tratamiento térmico y los embriones obtenidos, fueron colocadas y mantenidas en recipientes de 18 L con 15 L de agua de mar filtrada y esterilizadas a 35 UPS y temperatura promedio de 27 ºC, con recambio del 100 % del agua, cada 24 horas. Las larvas se alimentaron con la microalgas Chaetoceros calcitrans, Nannocloropsis sp., y Tretaselmis sp a una concentración de 20.000 cel./ml, de cada una. El desarrollo embrionario del Chione sp. se generó con toda normalidad, alcanzando todas sus fases larvales de la siguiente -

CRITICALLY ERODED BEACHES IN FLORIDA Updated, June 2009 BUREAU OF BEACHES AND COASTAL SYSTEMS DIVISION OF WATER RESOURCE MANAGEMENT DEPARTMENT OF ENVIRONMENTAL PROTECTION STATE OF FLORIDA Foreword This report provides an inventory of Florida's erosion problem areas fronting on the Atlantic Ocean, Straits of Florida, Gulf of Mexico, and the roughly seventy coastal barrier tidal inlets. The erosion problem areas are classified as either critical or noncritical and county maps and tables are provided to depict the areas designated critically and noncritically eroded. This report is periodically updated to include additions and deletions. A county index is provided on page 13, which includes the date of the last revision. All information is provided for planning purposes only and the user is cautioned to obtain the most recent erosion areas listing available. This report is also available on the following web site: http://www.dep.state.fl.us/beaches/uublications/tech-rut.htm APPROVED BY Michael R. Barnett, P.E., Bureau Chief Bureau of Beaches and Coastal Systems June, 2009 Introduction In 1986, pursuant to Sections 161.101 and 161.161, Florida Statutes, the Department of Natural Resources, Division of Beaches and Shores (now the Department of Environmental Protection, Bureau of Beaches and Coastal Systems) was charged with the responsibility to identify those beaches of the state which are critically eroding and to develop and maintain a comprehensive long-term management plan for their restoration. In 1989, a first list of erosion areas was developed based upon an abbreviated definition of critical erosion. That list included 217.6 miles of critical erosion and another 114.8 miles of noncritical erosion statewide. -

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.

Seagrass Targets for the Sarasota Bay Estuary Program
SEAGRASS TARGETS FOR THE SARASOTA BAY ESTUARY PROGRAM Prepared for: Sarasota Bay Estuary Program 111 South Orange Avenue Suite 200W Sarasota, FL 34236 Prepared by: Anthony Janicki, Michael Dema, and Ravic Nijbroek 1155 Eden Isle Drive NE St. Petersburg, FL 33704 December 2008 EXECUTIVE SUMMARY The objective of this project is to provide technically-defensible quantitative restoration and protection targets for seagrasses in the Sarasota Bay ecosystem. Establishment of seagrass targets provides a necessary basis for management decisions regarding water quality and other issues that can influence the distribution and persistence of this resource. The primary goal of this project is to maintain and/or restore seagrass coverage to its historic extent. Restoration targets were defined through an analysis of historic and recent aerial surveys of the study area. Historic photos of the area were taken in 1950; as many alterations have occurred to the shoreline in the study area, as well as channelization of the Intracoastal Waterway (ICW), the following analyses have accounted for these changes as non-restorable areas. Additionally, trends in seagrass coverage throughout the SBEP based on recent surveys have been identified. The methodology employed for this project is GIS-based. Historic aerial photos were used to establish a baseline extent of seagrass in the study area circa 1950. Recent trends in and persistence of seagrass throughout the SBEP were determined through analysis of GIS shapefiles based on aerial surveys executed by the SWFWMD since 1988. Due to anthropogenic modifications in the estuary such as shoreline build-out and the dredging of the Intracoastal Waterway (ICW), certain areas have been altered to the extent that they have no reasonable potential for restoration; these so-called non-restorable areas have been identified and removed from the analyses contained in this report.
