The stocking density and growth of young abalone Haliotis discus
hannai Ino cultured in the hanging net cage.
1988 11 pp
Bull. Nat. Fish. Res. Dev. Agency, 42: 59–69
Experiment of stocking density and growth of young abalone Haliotis discus hannai Ino in the hanging net cage by feeding green laver Ulva pertusa was conducted from April 18, to August 19, 1985 and results were summarized as follows. In the density experiment of 1,000–3,000 individuals/m2, the lower density of young abalone in the net cage showed the higher growth. The lower density of young abalone in the net cage showed the lower daily feeding rate and feed coefficient. Survival rate was over 92% in all densities during the experiment. In the size experiment, the smaller size of young abalone showed the higher growth and daily feeding rate. The smaller size of young abalone showed the lower feed coefficient and survival rate. Growth and daily feeding rate were increased with water temperature rising until 21.7°C, but these were decreased over 21,7°C. Generally, lower feed coefficient appeared in the water temperature range of 15.2°C to 21.7°C during experimental period. The survival rate was decreased as water temperature rose. The relationship between length and body weight expressed as follows: W = 0.0001345 L-3.05 where W means body weight and L shell length.

Effects of temperature, algal food, feeding rate and density on
the larval growth of the milk conch (strombus costatus) in Mexico.
1989 10 pp
Aquaculture, 76: 361–371
Effects of temperature, algal food, feeding rate and larval density on the development and shell growth stage of conch veligers, Strombus costatus, were studied over a period of 30 days in laboratory cultures. Experiments were conducted at 24°C, 28°C, 32°C and 28+-2°C. after hatching, the veligers developed to metamorphosis within 26 days at 28°C, 28 days at 28+-2°C and 35 days at 24°C. Rearing was not successful at 32°C. Conch larvae were fed with the algae Isochrysis aff. galbana (Tahiti), Tetraselmis chuii and Isochrysis/Tetraselmis mix. The best rate of growth per day was 39.69 um in Isochrysis/Tetraselmis mixed food. Experiments were conducted at 500, 1000, 2000, 3000, 4000, 5000 and 6000 Isochrysis aff. galbana cells larva-1 day-1. The veligers showed an optimal growth at 3000 cells larva-1 day-1. The conch veligers were reared at five larval densities: 100, 200, 300, 400 and 500 larvae/1, and showed an optimal growth at 100 larvae/1, while poorest growth was observed at 500 larvae/l.

Elements and innovations in the cultivation of red abalone
Haliotis Rufescens.
1984 18 pp
Aquaculture, 39, 375–392
Seven elements are described for cultivation of the red abalone, Haliotis rufescens: broodstock management; spawning induction, fertilization, and early development; larval cultivation; forage culture; settlement and early-juvenile-stage cultivation; weaning; and grow-out. Cultivation methods and equipment are described. Spawnable abalones are maintained on a year-round basis. Larvae are cultured in a flow-through apparatus that yields over 90% to the settling stage. A diatom slurry method is used to provide forage to the early benthonic and juvenile stages. Cultivation problems are described. Included are those with bacteria, Vibrio spp., and the maintenance of suitable diatom substrates for juvenile stages.
