Recently, many authors have considered the problem of simultaneous lo-calisation and mapping (SLAM). The paper addresses a somewhat diierent problem, that of cooperative localisation and mapping (CLAM). Basically, CLAM involves two or more robots cooperating to build a map of the environment. This cooperation is not aimed at simply increasing the speed with which the map is constructed; rather,...

Vibrio tapetis is the etiological agent of brown ring disease (BRD) in clams. Phenotypic, antigenic and genetic variability have been demonstrated, with three groups being established associated with host origin. In this work we analyze the variability of representative strains of these three groups, CECT 4600(T) and GR0202RD, isolated from Manila clam and carpet-shell clam, respectively, and H...

Quahog parasite unknown (QPX) is a protistan parasite capable of causing deadly infections in the hard clam Mercenaria mercenaria, one of the most valuable shellfish species in the USA. QPX is an extracellular parasite found mostly in the connective tissue of clam mantle and, in more severe cases of infection, other clam organs. Histopathologic examinations revealed that QPX cells within clam t...

The hard clam, Mercenaria mercenaria, is one of the most valuable commercial mollusk species along the eastern coast of the United States. Throughout the past 2 decades, the hard clam industry in the Northeast was significantly impacted by disease outbreaks caused by a lethal protistan parasite known as Quahog Parasite Unknown (QPX). QPX is an opportunistic pathogen and the infection has been s...

mon name “razor clam”. They gain that moniker due to their overall shape of being long and thin, in the nature of an old-time straight razor. Many species of razor clams are favorably recognized for their taste and texture and have been commercially harvested throughout the world. More recently, interest has been rising about developing methods to farm razor clams. It is important to understand...

The main goal of the present study was to investigate impact state environment on microbiota wedge clam Donax trunculus (Linnaeus, 1758) from region Arkutino (Bulgarian Black Sea aquatory). species Enterococcus hirae isolated during summer (from May August). P. mendocina prefers warmer months and alcaligenes colder ones. temperature followed a course decrease period September 2020 January 2021,...

Hemocytes are the immune effectors in clams, directing cellular but also humoral defences. In the Manila clam (Ruditapes philippinarum) and the carpet shell clam (Ruditapes decussatus), two phenotypically similar venerid species, fishery and aquaculture importance motivated scientific studies to improve knowledge about the participation of hemocytes in immune response. Currently, gaps still per...

Don Hoi Lord, a coastal wetland in the upper gulf of Thailand, is famous for the razor clam (Solen regularis), which is a source of food and income for local fishermen. However, the razor clam population is significantly decreasing so the aim of this study was to analyze the razor clam fishery and develop a management plan engaging the different stakeholders in collective discussions. A partici...

The assessment of clam yield potential and the identification of suitable sites for clam rearing are a necessary step to improve the economic and environmental sustainability of the exploitation activities in a regulated fishery. We discuss the development, validation and application of a method for estimating the clam yield potential of a northern Adriatic lagoon (Sacca di Goro, Italy) by comb...
