“…Observations on the egg case morphology of C. ramosus in the present study was comparable to that of reports of Mahmoud et al (2013). During the present study the number of egg cases and egg Sreejaya (2008) in B. spirata where the egg capsules turn into pink and opaque when the capsules were infected by bacteria or fungus and Naegel (2004) in Plicopurpu pansa. The results of Gallardo (1973) as well as Riquelme and Chavez (1991) suggested the development of purple colour in nonviable capsules due to bacterial infection.…”

“…In the present observation, from the total number of egg cases, 58% turned to purple colour indicating the decaying of egg cases after 15 days of post spawning. Similar observation was reported by Sreejaya (2008) in B. spirata where the egg capsules turn into pink and opaque when the capsules were infected by bacteria or fungus and Naegel (2004) in Plicopurpu pansa. The results of Gallardo (1973) as well as Riquelme and Chavez (1991) suggested the development of purple colour in nonviable capsules due to bacterial infection.…”

Lessons on broodstock maintenance, spawning, larval rearing and juvenile production of marine gastropods of ornamental value

Research on marine gastropod breeding in India is in its infancy and scanty literature is only available. To fill the lacunae, marine gastropods of three ornamentally valued and conservation important groups such as Cyprids, Strombids and Muricids were held under captivity and studied for their broodstock maintenance, spawning behaviour, larval rearing and metamorphosis into juveniles at the Shellfish Hatchery of Central Marine Fisheries Research Institute, Tuticorin. Valuable information on the focal themes of the article was obtained for Strombids and Muricids leading to the successful life cycle closing for Lambis lambis and Chicoreus virgineus are reported earlier. In the present study, experiments were conducted on aspects such as post-metamorphosed juvenile rearing up to 76 days post hatch for L. lambis, spawning, larval development and life cycle closing and reasonable level of juvenile production (8.8%) for Chicoreus ramosus. In addition, the primary observations on the captive breeding of Cypraea tigris with reference to its egg mass, brooding habit and early development is reported. However, while studying these groups few unanswered questions and bottle necks in their breeding nature, larval rearing and metamorphosis arose. The following account details the experiments conducted and results obtained in each of the focal themes of the paper and the constraints faced.

“…The only difference is the presence of sutures on the muricid capsules mentioned above. As noted by Naegel (2004), however, this feature is not universal for all muricids. Whether the Jurassic egg capsules also had a laminated capsule wall (e.g., Tamarin and Carriker 1967;Naegel 2004) is difficult to say as phosphatization could have obliterated such a feature.…”

Exceptionally preserved, phosphatized gastropod egg capsules from the uppermost Jurassic (upper Volgian) in Central Russia are reported. The egg capsules were attached to the inner side of the shell wall of empty body chambers of two ammonites. Due to phosphatization, the egg capsules retained their original morphology preserving both the lower attachment base and upper hemispherical cover. Comparison with recent and fossil gastropod egg capsules indicates that these were not produced by neritimorphs, the egg capsules of which are known from the Lower Jurassic and Upper Cretaceous. Since these fossil egg capsules share many similarities with those produced by some recent rissoids and muricid neogastropods, it is evident that they were produced by some representatives of Caenogastropoda. The abundant filamentous microbial structures, as well as micron-sized apatite globules, preserved inside the egg capsules suggest that phosphatization processes were mediated by microbial consortia under anaerobic and low-pH conditions.
