Biochemical and pharmacological studies have established that crustacean nervous system contains fairly large amounts of cholinesterase and acetylcholine or acetylcholine-like compounds (Nachmansohn and Rothenburg, '45; Schallek, '45; Augustinsson, '48; Walop, '50, '51; Walop and Boot, '50). The ability of lobster central ganglia to hydrolyze acetylcholine, and the effectiveness of extracts of ...

The pacemaker ganglion of the lobster heart is a functionally complete neural structure of nine cells which is capable of spontaneously producing bursts of actionpotential discharges separated by periods of relative inactivity. The burst discharge is maintained even when the ganglion is completely removed from the heart. The somata of five of the nine cells are quite large, approximately 60 /i ...

Copper is one of the most toxic metals for marine organisms. Biochemical changes occurring in the metabolically active tissues of gills (GL), hepatopancreas (HP) and muscles (MU) of the juvenile lobster, Panulirus homarus homarus on exposure to two sub-lethal doses (9.55 and 19.1 μg l) of copper were studied for 28 days of exposure (DoE). Sub-lethal doses of copper significantly (P<0.05) altere...

With a coastline of 3,260 km, a coastal area with more than 4,000 islands, and many lagoons giving protection against the waves and wind, Vietnam has great potential for seacage aquaculture. In Vietnam, seacage culture of lobsters started in the province of Khanh Hoa in 1992 and has expanded significantly around south-central Vietnam since 2000. Panulirus ornatus (ornate spiny lobster) is the m...

The spiny lobster Panulirus homarus, distributed along the Southeast and Southwest coasts of India, is an important commercial species having mariculture potential. Despite its importance, the structural and ultrastructure features of male gonads from this species have received scarce attention. Hence this study was aimed to describe the male reproductive tract of the species, using standard hi...
