Facultative and obligate symbiotic associations of Pomacea canaliculata (Caenogastropoda, Ampullariidae).
Pomacea canaliculata (Lamarck 1822) occurs mainly in lentic habitats throughout the lower Amazon basin and the Plata basin (Hylton-Scott, 1958; Martín et al., 2001). This Neotropical species has been introduced (ca. 1980) to several South East Asian countries for aquaculture, and has become a serious pest for rice and other crops (Halwart, 1994). Many Pacific islands are currently included in t...
متن کاملPhysiological response to low temperature in the freshwater apple snail, Pomacea canaliculata (Gastropoda: Ampullariidae).
Cold hardiness of the freshwater apple snail, Pomacea canaliculata, varies seasonally. We investigated lethal factors and physiological changes arising from exposure of P. canaliculata to low temperatures. Snails did not survive freezing. The supercooling point of cold-acclimated (cold tolerant) snails (-6.6+/-0.8 degrees C) did not differ significantly from that of non-acclimated ones (-7.1+/-...
متن کاملJuvenile growth and survival of the apple snail Pomacea canaliculata (Caenogastropoda: Ampullariidae) reared at different constant temperatures
BACKGROUND Pomacea canaliculata is a freshwater snail that cultured under certain conditions could provide interesting rewards in research and aquaculture. P. canaliculata is usually reared at 25°C, though the optimal temperature for culturing this species, that balances growth and survival rates, is so far unknown. In this work we present results of growth and survival of cohorts reared in the...
متن کاملImmune Defenses of the Invasive Apple Snail Pomacea canaliculata (Caenogastropoda, Ampullariidae): Phagocytic Hemocytes in the Circulation and the Kidney
Hemocytes in the circulation and kidney islets, as well as their phagocytic responses to microorganisms and fluorescent beads, have been studied in Pomacea canaliculata, using flow cytometry, light microscopy (including confocal laser scanning microscopy) and transmission electron microscopy (TEM). Three circulating hemocyte types (hyalinocytes, agranulocytes and granulocytes) were distinguishe...
متن کاملVariation in worm assemblages associated with Pomacea canaliculata (Caenogastropoda, Ampullariidae) in sites near the Río de la Plata estuary, Argentina.
Pomacea canaliculata is a common gastropod in freshwater habitats from Central and Northern Argentina, extending northwards into the Amazon basin. Several Platyhelminthes have been reported associated to P. canaliculata, sharing an intimate relationship with this gastropod host. The objectives of this study were to describe the symbiotic species assemblages associated to P. canaliculata in the ...
