Although snail farming is not at all a novel entrant in the animal husbandry field, it is still far from being widely accepted. Noting the excellent nutritional potential, characterized by high protein and mineral but low fat content of snails and considering the environmental benefits of making use of snails as human food, gastropods must be viewed as a source of nutritional comparable to or even superior to conventional livestock.

  • Husbandry of the Carnivorous Land Snail, Powelliphanta Augusta (Gastropoda: Pulmonata: Rhytdidae)
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ResearchArchive at Victoria University of Wellington Husbandry of the Carnivorous Land Snail, Powelliphanta augusta (Gastropoda: Pulmonata: Rhytdidae) By Thomas Edward Allan A thesis submitted to the Victoria University of Wellington in fulfillment of the requirements for the degree of Master of Science in Ecological Restoration Victoria University of Wellington 2010 1 Abstract Key aspects of the captive husbandry of Powelliphanta augusta, a newly-described New Zealand land snail are investigated: how they should be managed and fed to provide individuals for release, and how a long-term captive population can be maintained as an insurance against extinction in the wild. This project arises from almost all members of this species having been brought into captivity due to their displacement in the wild by an opencast coalmine. Powelliphanta (F: Rhytididae) is a genus of endemic carnivorous snails, which includes 10 species, 27 subspecies and numerous undescribed taxa. As well as its diversity, Powelliphanta is renowned for the large size of its members (up to 90mm diameter) and their attractively-patterned shells. Most taxa are threatened due to habitat loss and predation by introduced mammalian predators. The study commences with a literature review to refine husbandry methods and to assess requirements for captive breeding of snails. From this review investigations are made into stocking densities, substrate, reproductive biology, body condition and growth of the P. augusta captive population. To determine an appropriate stocking density for P. augusta groups of six snails were kept at two densities; with either 720cm2, or 1440cm2 per group.

    Mollusca Three Classes 1. Gastropoda (gastropods)~ slugs and snails 2. Bivalvia (bivalves) ~ clams and other two- shelled shellfish 3. Cephalopoda (cephalopods) ~ squids, octopuses and cuttlefish 1 Bodies of Mollusks • A mollusk has a soft body which is usually covered by a hard outer shell. • Exceptions: – Slugs and octopuses have lost their shells through evolution – Squids have very reduced shells Anatomy of a Mollusk • All mollusks have: – Foot ~ the muscular foot helps it move – Visceral mass ~ contains the gills, gut, and other organs – Mantle ~ covers the visceral mass to protect the mollusks without shells • Most mollusks have: – Shell ~ protects the mollusk from predators and keeps land mollusks from drying out. 2 Symmetry of Mollusks • Mollusks have bilateral symmetry. – The two halves of the body mirror each other. Anatomy of a Snail (gastropod) 3 Anatomy of a Clam (bivalve) Anatomy of a Squid (cephalopod) 4 Eating Behaviors • Bivalves (clams) ~ filter tiny plant and bacteria from the water • Gastropods (snails) ~ eat with a radula (tiny tongue covered with teeth. – The radula is used to scrape algae off rocks and pieces of leaves and seaweed • Cephalopods (squid) ~use tentacles to grab their prey and put it in their powerful jaws.

  • Endemic Land Snail Fauna (Mollusca) on a Remote Peninsula in the Ogasawara Archipelago, Northwestern Pacific1
    Endemic Land Snail Fauna (Mollusca) on a Remote Peninsula in the Ogasawara Archipelago, Northwestern Pacific1 Satoshi Chiba2,3, Angus Davison,4 and Hideaki Mori3 Abstract: Historically, the Ogasawara Archipelago harbored more than 90 na- tive land snail species, 90% of which were endemic. Unfortunately, about 40% of the species have already gone extinct across the entire archipelago. On Haha- jima, the second-largest island and the one on which the greatest number of species was recorded, more than 50% of species are thought to have been lost. We report here the results of a recent survey of the snails of a remote peninsula, Higashizaki, on the eastern coast of Hahajima. Although the peninsula is small (@0.3 km2) and only part is covered by forest (<0.1 km2), we found 12 land snail species, all of which are endemic to Ogasawara. Among these species, five had been thought to already be extinct on Hahajima, including Ogasawarana yoshi- warana and Hirasea acutissima. Of the former, there has been no record since its original description in 1902. Except for the much larger island of Anijima and the main part of Hahajima, no single region on the Ogasawara Archipelago maintains as great a number of native land snail species. It is probable that the land snail fauna of the Higashizaki Peninsula is exceptionally well preserved be- cause of a lack of anthropogenic disturbance and introduced species. In some circumstances, even an extremely small area can be an important and effective refuge for threatened land snail faunas. The native land snail fauna of the Pacific one such example: of 95 recorded species, islands is one of the most seriously endan- more than 90% are endemic (Kuroda 1930, gered faunas in the world (e.g., Murray et al.

ABSTRACT: An experiment was conducted to study the performance of growing snails fed a basal diet of milk leaf (Euphorbia heterophylla) supplemented with calcium from three sources (egg shell, oyster shell and bone meal). A total of 120 growing snails with weight range of 100- 110g were randomly allotted to four treatment groups (T1, T2, T3 and T4), replicated three times with 10 snails per replicate in a completely randomized design. The snails on T1, T2 and T3 were fed with milk leaf supplemented with egg shell, oyster shell and bone meal as calcium sources respectively. T4 consisted of snails fed with milk leaf alone. The feeding trial lasted 13 weeks. Calcium supplements analysed contained 73.6% calcium for eggshell, 59.4% calcium for oyster shell and 33.2% calcium for bone meal. The results showed that the total weight gain, shell length, shell width and shell thickness was highest with snails on egg shell (T1). Snails on bonemeal as the calcium supplement (T3) recorded the highest mortality of 40% and had the poorest performance which was similar to those of snails on control diet of milk leaf alone (T4).

  • Structure and Function of the Digestive System in Molluscs
    Cell and Tissue Research (2019) 377:475–503 https://doi.org/10.1007/s00441-019-03085-9 REVIEW Structure and function of the digestive system in molluscs Alexandre Lobo-da-Cunha1,2 Received: 21 February 2019 /Accepted: 26 July 2019 /Published online: 2 September 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The phylum Mollusca is one of the largest and more diversified among metazoan phyla, comprising many thousand species living in ocean, freshwater and terrestrial ecosystems. Mollusc-feeding biology is highly diverse, including omnivorous grazers, herbivores, carnivorous scavengers and predators, and even some parasitic species. Consequently, their digestive system presents many adaptive variations. The digestive tract starting in the mouth consists of the buccal cavity, oesophagus, stomach and intestine ending in the anus. Several types of glands are associated, namely, oral and salivary glands, oesophageal glands, digestive gland and, in some cases, anal glands. The digestive gland is the largest and more important for digestion and nutrient absorption. The digestive system of each of the eight extant molluscan classes is reviewed, highlighting the most recent data available on histological, ultrastructural and functional aspects of tissues and cells involved in nutrient absorption, intracellular and extracellular digestion, with emphasis on glandular tissues. Keywords Digestive tract . Digestive gland . Salivary glands . Mollusca . Ultrastructure Introduction and visceral mass. The visceral mass is dorsally covered by the mantle tissues that frequently extend outwards to create a The phylum Mollusca is considered the second largest among flap around the body forming a space in between known as metazoans, surpassed only by the arthropods in a number of pallial or mantle cavity.

  • Stimulation of Genital Eversion in the Land Snail Helix Aspersa by Extracts of the Glands of the Dart Apparatus DANIEL J.D
    THE JOURNAL OF EXPERIMENTAL ZOOLOGY 238:129-139 (1986) Stimulation of Genital Eversion in the Land Snail Helix aspersa by Extracts of the Glands of the Dart Apparatus DANIEL J.D. CHUNG Division of Biological Sciences, and Museum of Zoology, University of Michigan, Ann Arbor, MI 48109 ABSTRACT The dart apparatus, used during courtship in some groups of hermaphroditic land snails, has long been assumed to have a “stimulatory” effect on the mating partner, though how stimulation occurs and exactly what function it serves has never been determined. In this study, extracts of the mucous glands of the dart apparatus of the land snail Helix aspersa were injected into conspecifics and into a related snail, Cepaea nemoralis, in order to test the hypothesis that the dart is used to achieve inflow of bioactive mucous gland secretions into the darted snail. Helix aspersa injected with the extract responded by everting their terminal genitals; eversion normally takes place during courtship and mating. Boiling the extract increased the bioactiv- ity. Pronase-treated extract lost bioactivity, and gel filtration of the boiled extract indicated that the active substance has a molecular weight of about 5,000. The active substance may be a polypeptide. Cepaea nemoralis also everted their genitals when injected with the boiled Helix extract. The active substance appears to be a contact sex pheromone, the second such pheromone in a pulmonate land snail for which experimental evidence has been obtained. Accessory organs in the terminal genitalia dart might cause increased tonus of the pen- of the hermaphroditic land snail order Sty- ial muscles.

The diverse and unique shell shapes are interesting to draw. The easiest medium to describe the shape of a mollusk is in two dimensions. This study aims to identify various images of mollusks in two-dimensional print media such as cloth, paper and plates. Based on the 10 sources of photos analyzed, 56 species of mollusks from 38 families were identified. The Gastropod class dominates with 45 species from 31 families, followed by Bivalves with 7 species from 5 families, then Cephalopods with 4 species from 2 families. Some of the problems found are the shape and proportion of images that different with specimens, some inverted or cropped images, different direction of rotation of the shells with specimens, and different colour patterns with specimens. Biological and distributional aspects of several families will be discussed briefly in this paper.
