Haliotis asinina Linne′ by completely randomized design with 3 replicates for 28 weeks. Abstract Marine protected areas (MPA) are tools for integrated coastal management (ICM); they have gained worldwide acceptance as a strategy for resource restoration and conservation. Culture conditions at a pH of 7.8–8.0, a temperature of 27–28°C, and 31–32% salinity yielded cell growth expansion from the explanted tissue. Background Aggregation affects the fertilization rate of species that utilize external fertilization. Haliotis asinina is the largest of the tropical abalone species and occurs throughout the Indo-Pacific, including eastern Indonesian waters. The effects of the chemical inducers, gamma-aminobutyric acid (GABA) and potassium chloride (KCl), on the larval settlement and metamorphosis of the donkey-ear abalone, Haliotis asinina, was investigated. The increase in sea surface temperature associated with climate change can cause tremendous impact on the different life stages of aquatic organisms, particularly on the tropical species.
Amplified fragment length polymorphism (AFLP) analysis was carried out on representative individuals of wild Haliotis asinina using 64 primer combinations. Calcium-bearing minerals comprise about 50% of biominerals with the most common being polymorphs of calcium carbonate, e.g.
abalone species and occurs throughout the Indo-Pacific, including eastern Indonesian waters. is a tropical abalone species, commonly known as the donkey’s or ass`s ear abalone. The present study investigates the effect of elevated temperature on hatching rate, growth and survival of larvae and breeders of tropical mollusk, donkey’s ear abalone (Haliotis asinina). A semiclosed recirculating land-based system was used with stocking densities of 368, 735, and 1,100 individuals/m2. The use of probionts has been considered to be an effective technology in enhancing growth performances and survival rate of aquaculture species. asinina can be modified to enhance the consumption of highly nutritious but lower preference species. For primarily sedentary marine invertebrates with indirect development, the majority of dispersal occurs during the larval stage.

Control of shell pigmentation by secretory tubules in the abalone mantle Control of shell pigmentation by secretory tubules in the abalone mantle.
One evolutionary route from a pit-eyed ancestor resulted in the eyes of the abalone Haliotis and the cephalopod mollusc Nautilus (Figure 2(a)). Nacre (known as mother of pearl) is the iridescent inner shell layer of some mollusks. However, the process of aggregation has not been studied in detail, using either theoretical models or real world observations. A method of marking abalone (Haliotis asinina Linne) for sea ranching and stock enhancement purposes was developed.
The tropical abalone species Haliotis asinina is a particularly good model with which to investigate the chemical basis of aggregation, given that spawning occurs in a 2-week cycle over the summer period and with the appearance of the new and full moons . Research must gauge the effectiveness of MPA implementation in promoting fisheries recovery. small (1-2 cm in shell-length) medium (3-4 cm in shell-length) and large (5-6 cm in shell-length) were selected and further tested for determination of changes in the rate of oxygen consumption for 24 hours period. Key Words: Haliotis asinina, climate change, elevated temperature, breeders, larvae. Gill and heart tissues from the abalone Haliotis asinina were cultured in vitro using Leibovitz L15 medium supplemented with insulinlike growth factor and basic fibroblast growth factor.
The size of the plastic cages used throughout this experiment was 30?40?30 cm.

The amplified 16S rDNA of individuals representing those haplotypes were cloned and sequenced and tested for specificity.
Increase in global atmospheric temperature has been progressing with high speed for the last 50 years. Almost 85% of the secretome encodes novel proteins; remarkably, only 19% of these have identifiable homologues in the full genome of the patellogastropod Lottia scutum. It was set to determine their effects on rearing of the abalone, Haliotis asinina Linne by completely randomized design with 3 replicates for 28 weeks.
The purpose of this study was to isolate, select and characterize lactic acid bacteria (LAB) from abalone as a potential candidate probiotic in abalone cultivation system. Molecular analysis of two FMRFamide-encoding transcripts expressed during the development of the tropical abalone Haliotis asinina. The abalone, Haliotis asinina, is a large, highly active tropical abalone that feeds at night on shallow coral reefs where oxygen levels of the water may be low. There is intense abalone collection from reef areas, which has led to decreasing harvest in recent years. Correlating gene expression with larval competence, and the effect of age and parentage on metamorphosis in the tropical abalone Haliotis asinina. The sex ratio of wild abalone (>60 mm shell length) collected from Panagatan Cays, Antique, Philippines was approximately 1:1.
Female abalone spawned with a mean of 1,202,900 larvae.
Modelling predicts that surface temperature will rise to 1.8-4.0°C globally by 2100 (IPCC 2007). This study aims to analyze the biological aspects of tropical abalone (Haliotis asinina L) comprising distribution of abalone size, length and weight correlation and feeding habit. asinina is one of the priority species for study at SEAFDEC Aquaculture Department. For example, ganglia from the gastropods Aplysia and Lymnaea are known to produce neuropeptides related to growth, feeding behavior, and reproduction. Stocking densities of 40, 60, 80 and 100 pcs/cage, with an initial size range of 4-5, 7-8 and 10-11 mm were cultured in plastic cages measuring 30×40×30 cm.

In this report we show that injections of APGW-amide into 4-mo-old juvenile Haliotis asinina stimulate growth of body weight and, to a lesser degree, shell length. The main purpose of this study was to test and understand the effectivity of previous successful treatment to induce spawning in temperate abalone, including the use of hydrogen peroxide, vigorous aeration, desiccation, thermal shock, and UV-irradiated seawater, to induce spawning in the tropical abalone (Haliotis asinina) from southern Lombok waters, NTB.
As the organism and shell grow, new apertures are formed and the preceding ones are filled in. Haliotis asinina, common name the ass's-ear abalone, is a fairly large species of sea snail, a tropical gastropod mollusk in the family Haliotidae, the abalones, also known as ormers or paua.Both the common name and the scientific name are based on the shape of the shell, which is long, narrow and curved, resembling the shape of a donkey's ear. The SMR covers 32,000 ha or 59% of coastal waters north of the mainland Sagay City. Growth of ass's ear abalone (Haliotis asinina) was measured in situ (mark-recapture of adults) and in aquaria (juveniles) on Heron Reef, Queensland. Digenean trematodes infecting the tropical abalone Haliotis asinina have species-specific cercarial emergence patterns that follow daily or semilunar spawning cycles. In 2002, the production of abalones was 4.076 ton from total production of marine fisheries in the world 8.000 ton. The sex ratio (female:male) in the present study was 1:1.7 and the proportion of females was 36.6% (n=106/290).

Warrant, in Encyclopedia of Animal Behavior, 2010.
Moreover, survival rates are not effected by density, type of structure and setting position (depth). Recently, the creation of hatcheries allowed the production of cultured animals, and aquaculture is in progress. The GI microbiota of abalone contains a highly complex bacterial assemblage playing an essential role in the overall health of these gastropods. To determine the feed seaweed good for growing abalone then performed analysis of variance. This abalone is widely distributed throughout the Indo-Pacific, prim-arily inhabiting intertidal reef flats. This shareable PDF can be hosted on any platform or network and is fully compliant with publisher copyright. asin-ina is the most common haliotid in the Philippines, and has formed the major basis of the abalone ﬁshery production in the country due to its relatively large size. asinina likes special habitat types, such as rocky habitats overgrown with algae and seagrass habitats.
