Profile of Nutrition and Hazards of Om-Elkholool (Donax Trunculus) and Gandofly (Ruditapes Decussatus) Clams from Alexandria, Egypt
International Journal For Research In Agricultural And Food Science ISSN: 2208-2719 Profile of Nutrition and Hazards of Om-Elkholool (Donax Trunculus) and Gandofly (Ruditapes Decussatus) Clams From Alexandria, Egypt Sherief Mohammed Sayed Abd-Allah Assistant Professor, Department of Food Hygiene "Meat Hygiene", Faculty of Veterinary Medicine, Assiut University, Assiut 71526, Egypt Email:[email protected] ABSTRACT Clams are delicate nutritious food; however they can harbor potential health hazards. The current work aimed to investigate and compare some of the nutritive criteria and hazards of Om-Elkholool (Donax trunculus) and Gandofly (Ruditapes decussatus) clams sold at Alexandria, Egypt. A total of 46 samples (22 of Om-Elkholool and 24 of Gandofly) were randomly collected from fish retailers during summer of 2017. Samples were analyzed for proximate composition (dry matter, moisture, protein, fat, and ash %). The carbohydrates and energy content was calculated. The count of coliforms, fecal coliforms, E. coli and Cl. perfringenes (MPN/g) was determined. Concentration (mg/kg) of lead and cadmium in 10 randomly selected samples of each type were estimated. The dry matter, moisture, protein, fat, ash and carbohydrates percentages mean values for Om-Elkholool “Om” samples were 30.37±0.22, 69.60±0.21, 8.49±0.14, 1.29±0.03, 18.63±0.09, and 1.99±11, respectively, while for Gandofly “Gd” samples were 16.81±0.21, 83.28±0.2, 8.69±0.13, 1.22±0.03, 3.43±0.09, and 3.37±10, respectively. The gross energy content (Kcal/100g) mean value was 53.55±0.88 for Om and 59.24±0.85 for Gd. -
Donacidae - Bivalvia)
Bolm. Zool., Univ. S. P aub 3:121-142, 1978 FUNCTIONAL ANATOMY OF DON AX HANLEY ANUS PHILIPPI 1847 (DONACIDAE - BIVALVIA) Walter Narchi Department o f Zoology University o f São Paulo, Brazil ABSTRACT Donax hanleyanus Philippi 1847 occurs throughout the southern half o f the Brazilian littoral. The main organ systems were studied in the living animal, particular attention being paid to the cilia ry feeding and cleasing mechanisms in the mantle cavity. The anatomy, functioning of the stomach and the ciliary sorting mechanisms are described. The stomach unlike that of almost all species of Donax and like the majority of the Tellinacea belongs to type V, as defined by Purchon, and could be regarded as advanced for the Donacidae. A general comparison has been made between the known species of Donax and some features of Iphigenia brasiliensis Lamarck 1818, also a donacid. INTRODUCTION Very little is known of donacid bivalves from the Brazilian littoral. Except for the publications of Narchi (1972; 1974) on Iphigenia brasiliensis and some ecological and adaptative features on Donax hanleyanus, all references to them are brief descrip tions of the shell and cheklists drawn up from systematic surveys. Beach clams of the genus Donax inhabit intertidal sandy shores in most parts of the world. Donax hanleyanus Philippi 1847 is one of four species occuring through out the Brazilian littoral. Its known range includes Espirito Santo State and the sou thern Atlantic shoreline down to Uruguay (Rios, 1975). According to Penchaszadeh & Olivier (1975) the species occur in the littoral of Argentina. 122 Walter Narchi The species is fairly common in São Paulo, Parana and Santa Catarina States whe re it is used as food by the coastal population (Goffeijé, 1950), and is known as “na- nini” It is known by the name “beguara” (Ihering, 1897) in the Iguape region, but not in S. -

Estructura Poblacional De Donax Striatus (Bivalvia, Donacidae) En Playa Las Balsas, Gibara, Cuba
ESTRUCTURA POBLACIONAL DE DONAX STRIATUS (BIVALVIA, DONACIDAE) EN PLAYA LAS BALSAS, GIBARA, CUBA Frank A. Ocaña Borrego1*, Alejandro Fernández1, Alexis Silva2, Pedro A. González1 y Yamilet García2 RESUMEN Donax striatus Linné 1767 es una de las dos especies de almejas de playa que se encuentra en el Caribe. Pocas investigaciones se han centrado en describir aspectos sobre la estructura poblacional de esta especie. Una po- blación de D. striatus fue muestreada mensualmente desde febrero del 2008 hasta enero del 2009 en playa Las Balsas, Gibara, Cuba. La población mostró fluctuaciones estacionales de la densidad, presentando los mayores valores en los meses de mayo y octubre del 2008 y enero del 2009. Se encontraron tres picos de reclutamiento: abril-mayo, agosto del 2008 y enero del 2009. Se observó una distribución estratificada por grupos de tallas: los reclutas fueron registrados en los estratos superiores de la playa y los adultos, fundamentalmente, en los es- tratos bajos. La mayor abundancia se localizó en el estrato intermedio. No hubo correlación entre los cambios mensuales de densidad con las temperaturas, ni con las precipitaciones, sin embargo, parece que los cambios en el régimen habitual del oleaje y la elevación del nivel medio del mar tienen influencia sobre el comporta- miento de la abundancia de esta especie. Se propone una hipótesis que combina parámetros morfodinámicos para explicar la distribución vertical de los diferentes componentes de la población. Palabras claves: Bivalvia, Donax, playas arenosas, estructura poblacional, Cuba. ABSTRACT Donax striatus Linné 1767 is one of the two beach clam species that inhabits in the Caribbean. Few in- vestigations have focused on describing aspects related with the population structure of this species. -

During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the type- and only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. -
Phylogenetic Systematics and the Evolutionary History of Some Intestinal Flatworm Parasites (Trematoda: Digenea: Plagiorchi01dea) of Anurans

Department of Zoology The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date: March 24, 1987 i i Abstract Historical structuralism is presented as a research program in evolutionary biology. It uses patterns of common ancestry as initial hypotheses in explaining evolutionary history. Such patterns, represented by phylogenetic trees, or cladograms, are postulates of persistent ancestral traits. These traits are evidence of historical constraints on evolutionary change. Patterns and processes consistent with a cladogram are considered to be consistent with an initial hypothesis of historical constraint. As an application of historical structuralism, a phylogenetic analysis is presented for members of the digenean plagiorchioid genera Glypthelmins Stafford, 1905 and Haplometrana Lucker, 1931. -

Moreover he works 25 centuries ago, and set it against current knowledge. The created the science of biology and the philosophy of analysis of information derived from a thorough study of his biology, while his animal studies profoundly infl uenced zoological writings revealed 866 records related to animals cur- rently classifi ed as marine invertebrates. These records corre- the origins of modern biology (Lennox, 2001a). His sponded to 94 different animal names or descriptive phrases which biological writings, constituting over 25% of the surviv- were assigned to 85 current marine invertebrate taxa, mostly ing Aristotelian corpus, have happily been the subject (58%) at the species level. A detailed, annotated catalogue of all of an increasing amount of attention lately, since both marine anhaima (a = without, haima = blood) appearing in Ar- philosophers and biologists believe that they might help istotle’s zoological works was constructed and several older in the understanding of other important issues of his confusions were clarifi ed. -

Long Beach Island 2014 FONSI and Final EA
FINDING OF NO SIGNIFICANT IMPACT Issuance of a Negotiated Agreement Authorizing Use of Outer Continental Shelf Sand from Borrow Area D2 in the Barnegat Inlet to Little Egg Inlet (Long Beach Island), New Jersey Storm Damage Reduction Project Pursuant to the National Environmental Policy Act (NEPA) and Council on Environmental Quality (CEQ) regulations implementing NEPA (40 CFR 1500-1508), the U.S. Army Corps of Engineers Philadelphia District (Corps), in cooperation with the Bureau of Ocean Energy Management (BOEM), prepared an environmental assessment (EA) to determine whether the proposed use of Outer Continental Shelf (OCS) sand resources (Borrow Area D2) in the Long Beach Island (NJ) Storm Damage Reduction Project (Project) would have a significant effect on the human environment and whether an environmental impact statement (EIS) should be prepared. Pursuant to the Department of the Interior (DOI) regulations implementing NEPA (43 CFR 46), BOEM has independently reviewed the EA and determined that the potential impacts of the proposed action have been adequately addressed. Proposed Action BOEM’s proposed action is the issuance of a negotiated agreement to authorize use of D2 so that the project proponents, the Corps and the New Jersey Department of Environmental Protection (NJDEP) (non-federal sponsor), can obtain up to 7 million cubic yards (MCY) of OCS sand for the Project. The Corps’ proposed action is the nourishment of approximately 16.9 miles of shoreline, of which 4.5 miles have already been constructed. The purpose of BOEM’s proposed action is to respond to the Corps’ and NJDEP’s request for use of OCS sand under the authority granted to the DOI by the Outer Continental Shelf Lands Act (OCSLA). -
