Short communication: Effects of induced spawning on early development in snout otter clam, Lutraria philippinarum (Deshayes, 1854) (Bivalvia: Mactridae)

The reproductive biology of Lutraria philippinarum (Veneroida: Mactridae) and its fishery in the Philippines.

The Snout Otter Clam, Lutraria philippinarum is a regularly harvested bivalve species for food and also as a source of income in the Philippines. For sustainable supply of this resource in the wild, efficient and effective management strategies are needed, and the evaluation of its reproductive biology and fishery are required. In this study, the reproductive biology and fishery of L. philippin...

India ink induces apoptosis in the yellow clam Mesodesma mactroides (Deshayes, 1854). Optical and ultrastructural study.

This paper reports on the acute inflammatory and cellular process in the yellow clam, Mesodesma mactroides, induced by injection of India ink into the muscular foot. Histological observations with optical and electronic microscopy were made at 24 and 48 h after injection. The induced cellular inflammatory response consisted of a general hemocyte infiltration without necrosis and apoptotic activ...

Assimilation of bacteria by the dwarf surf clam Mulinia lateralis (Bivalvia: Mactridae)

Estimation of assimilation efficiency of bivalves, fed with radiolabeled bacteria, differs substantially depending on choice of tracer. We have investigated assimilation of bactena by the dwarf surf clam MuLinia lateralis (Say) using bacteria labeled w t h either ~ [ ~ ~ S ] m e t h i o n i n e or [ m e t h y l 3 ~ ] thymidme. Labeled bacteria were fed to M. lateralis 6.18 f 0.45 mm (mean +SD) ...

Endogenous circatidal rhythm in the Manila clam Ruditapes philippinarum (Bivalvia: Veneridae)

Manila clams, Ruditapes philippinarum, removed from their natural environment and maintained for 9 weeks in continuously immersed conditions exhibited a clear endogenous circatidal rhythm in oxygen consumption. The clams exhibited a semidiurnal rhythmicity in oxygen consumption after showing a diurnal pattern in the ®rst few days (5 to 7 d) of the experiment. The results of the present study in...
