“…This is of the same order of magnitude as values recorded in the literature for the metabolic rates of Nucella lapillus (Bayne & Scullard 1978), Littorina littorea (Sandeen et al 1954, Newell & Pye 1971 and Haliotis tuberculata (Peck et al 1987) (see also Bayne &Newell 1983 andGraham 1994 for reviews). It should be noted that the metabolic values obtained here represent a mean metabolic rate for individuals that were both active and stationary.…”

The phenomenon of shell wiping in Calliostoma zizyphinum (L.) was investigated with regard to its potential function as a feeding adaptation. It was determined that C. zizyphinum will, on average, wipe the surface of its shell with its foot twice every 24 h, in the process consuming any matter that has adhered to the pedal mucus present on the surface of its shell. Examination of the importance of shell wiping to C. zizyphinum, both as a mechanism to reduce shell fouling and as a source of nutrition, revealed that the prevention of shell wiping resulted in a reduction in shell growth by a factor of 0.67 and an increase in shell fouling by a factor of 9. Measurement of the metabolic rate of C. zizyphinum ascertained that an average sized adult had a metabolic requirement of ~117 J 24 h -1 . Examination of the ability of the pedal mucus produced by C. zizyphinum to act as a provendering agent showed that the pedal mucus produced by C. zizyphinum could increase the entrapment of particulate matter by a factor of 8, and increase the chlorophyll a content of a substratum by a factor of 3. Calculation of the potential contribution of the matter trapped by pedal mucus, which is ingested through shell wiping, to the daily energetic requirements of C. zizyphinum revealed that shell wiping can contribute to approximately one-fifth of the daily energetic requirement of C. zizyphinum. Shell wiping therefore has an important role for both feeding and antifouling in C. zizyphinum.

“…This species has a distribution from the Azores in the west, the Mediterranean in the east, the West African coast in the south and the Channel Islands in the north. The ecology of H. tuberculata has been the subject of intense study (Forster 1962, 1967, Hayashi 1980a, Peck 1983, 1989, Peck et al 1987, Peck & Culley 1990, Mgaya & Mercer 1994. H. tuberculata is dioecious and sexes are easily distinguished by examining the large gonad visible from the underside of the shell (Hayashi 1980b).…”

A series of laboratory experiments was conducted to determine fertilization success in the commercial abalone Haliotis tuberculata L. Fertilization success is a function of sperm dilution, sperm-egg ratio, gamete age and the amount of time sperm and eggs are in contact. Sperm density required for optimum fertilization success in vivo, using 10 ml culture volume, was in the range 5 × 10 4 to 5 × 10 5 sperm ml -1. When these experiments were repeated using 500 ml culture volume, results showed high levels of fertilization success across a far larger range of sperm dilutions with success > 80% at 10 3 sperm ml -1. Sperm-egg ratios of >100:1 have little effect on fertilization success, but below these levels this factor becomes significant. Viability of both sperm and eggs decreased with age so that no fertilization occurred after 2.5 h. Maximum fertilization success occurred after 30 min sperm-egg contact time. These data suggest that sperm limitation may severely compromise reproductive success in exploited populations of H. tuberculata.

“…Maybe the animals from the varying ageing groups contributed to the lower growth rates recorded in the present experiments. Experimental evidence showed most of the energy budget for the young goes to somatic growth, and to respiration for adults in H. tuberculata (Peck, Culley & Helm 1987) H. asinina (Capinpin & Corre 1996). Results from Experiment 1 in this study showed a relative higher growth rate (about 116.97 lm day…”

Pacific abalone (Haliotis discus hannai Ino) aquaculture is a thriving industry in China. This study describes a novel submerged cage culture system for abalone rearing in Fujian, South China. The cage consisted of five vertical slots that were oriented perpendicular to the flow of water. The slots were separated by six vertically connected plastic plates for abalone attachment and shelter at the bottom of the cage. Experiment 1 was designed to determine the appropriate stocking density at the start of the abalone sea-based production cycle. Eight-month-old hatchery reared and size-graded juveniles were transferred to the sea-based culture system. For different stocking densities, shell length of juveniles obtained in this novel culture system on 2, 3.5 and 5 months, respectively, was compared with shell lengths obtained in a traditionally multi-tier basket culture system. In Experiment 2, daily growth rates (DGRs) in shell length and biomass in terms of wet weight of 2-year-old abalones reared in cage and tiered basket culture systems were compared over a 6-month period. Results of Experiment 1 showed that growth of abalone in the cage culture system is density-dependent; the mean final shell length of juveniles obtained was 6.7-15.9% higher than in tiered baskets system even at the same initial stocking density. In Experiment 2, DGRs in shell length of 53.83-78.38 lm day À1 obtained in cage system were significantly higher than that in tiered baskets (P < 0.01). And in terms of wet weight biomass, it was 1.48-3.01 times higher in the cage system compared with the traditional system. Abalone survival was more than 87.5% in both culture systems in both experiments. Advantages of the newly established cage culture system included better growth performance of the animals reared and potential improvement of rearing conditions, such as improved water flow velocity and dissolved oxygen.
