Shell height (SH) and total weight (TW) were measured monthly and temperature was recorded daily. The growth of oysters is characterized by fast initial ...
Annual reproductive effort of Pacific winged pearl oyster Pteria sterna and its relation with the timing for planning pearl seeding operations.(Report)
Aug 01, 2009; Caceres-Puig, Jorge I. ... ABSTRACT Using a combination of stereological and calorimetric methods, we studied reproductive effort of Pacific winged pearl oyster Pteria sterna during ah annual cycle in Bahia de La Paz, B.C.S., Mexico. The relationship between changes in the volumetric fraction of germinal and somatic ...
Enhancing the potential for population recovery: restoration options for bay scallop populations, Argopecten irradians concentricus, in North Carolina.(Report)
Aug 01, 2009; Fegley, Stephen R. ... ABSTRACT Historically depressed bay scallop populations in North Carolina have retained some capacity to replenish themselves. However, continued abnormally high predation by cownose rays, and growing degradation of seagrass beds may limit bay scallop population recovery. We modified ...
Comparison between in vivo force recordings during escape responses and in vitro contractile capacities in the sea scallop Placopecten magellanicus.(Report)
Aug 01, 2009; Perez, Hernan Mauricio ... ABSTRACT During their escape response, scallops swim, using jet propulsion created by rhythmically opening and closing their valves. Valve closure is powered by the large adductor muscle that acts against the hinge ligament. We compared in vivo force production during escape responses and ...
Spatial and temporal variation in the shell height/meat weight relationship of the sea scallop Placopecten magellanicus in the Georges Bank fishery.(Report)
Aug 01, 2009; Sarro, Christopher L. ... ABSTRACT Spatial and temporal variations in the meat weight of sea scallops were examined in the Georges Bank fishery. From 1998-2007, 31 commercial scallop vessels supplied 145 dissections from the last tow of their fishing trip. During the dissection process we recorded the shell height, ...
Natural variation in larval size and developmental rate of the northern quahog Mercenaria mercenaria and associated effects on larval and juvenile fitness.(Report)
Aug 01, 2009; Przeslawski, R. ... ABSTRACT Larval size and developmental rate can vary tremendously within and among cohorts because of genetics, environment, and maternal investment. This natural variation in larvae may have effects that span multiple life stages. Here we investigate the effects of larval size and ...
Population structure, growth, and production of the wedge clam Donax hanleyanus (Bivalvia: Donacidae) from northern Argentinean beaches.(Report)
Aug 01, 2009; Herrmann, Marko ... ABSTRACT Donax hanleyanus Philippi, 1847 (Bivalvia: Donacidae) dominates fine to coarse sandy beach communities of the northern Argentinean Atlantic coast. The population biology of this intertidal wedge clam was studied by determining population structure, growth and production at the ...
Involvement of [Ca.sup.2+] signaling pathway during oocyte maturation of the northern quahog Mercenaria mercenaria.(Report)
Aug 01, 2009; Zhang, Tao ... ABSTRACT In many molluscs, it has been found that [Ca.sup.2+] signaling pathway is involved in the resumption of meiotic maturation in oocytes. To better understand the possible role of [Ca.sup.2+] signaling pathway in regulating meiotic maturation in oocytes of the northern quahog ...
