Sugawara K., and S. Kadowaki. 2006. Landbased aquaculture system of abalone using the
recycled frozen ship container. Aquaculture Magazine 555, 70-73.
The authors proposed landbased polyculture of abalone and seaweed using the recycled frozen
ship container. They compared the complex poly-eco-aquaculture of abalone, seaweed and
bacteria with conventional landbased aquaculture. In the new system, they maintained best
abalone growth temperature (18 ± 1.5 ℃) using low cost home air-conditioner. They mentioned
that using seaweed to purify water for abalone is a new farming system for future. They achived
faster growth of hybride (ezo abalone and megai abalone) abalone by supplying artificial feed.
This type of aquaculture can supply safe seafood for consumers. They suggested this poly-ecoaquaculture
for sustainable production of abalone.
Harris J.O., G.B. Maguire, S. Edwards, and S.M. Hindrum. 1998. Effect of ammonia on the
growth rate and oxygen consumption of juvenile greenlip abalone, Haliotis laeÍigata Donovan.
Aquaculture 160, 259–272.
The authors assessed the chronic toxicity of unionised ammonia in terms of growth rate, food
consumption rate and oxygen consumption rate for juvenile greenlip abalone, Haliotis laevigata.
They found that Juvenile greenlip abalone were sensitive to ammonia as indicated by depressed
growth rate and food consumption. They observed that free ammonia nitrogen (FAN)
concentrations exceeding 0.031 mg L –1 supressed abalone (Haliotis laevigata) growth rates, and
FAN concentrations of 0.041 and 0.158 mg L -1 reduced abalone growth (whole weight basis) 5
(EC 5 ) and 50% (EC 50 ) respectively. Oxygen consumption rate increased to a maximum of 188%
of control values at 0.235 mg FAN L -1 and decreased slightly at the highest concentration of
0.418 mg FAN L -1 .

D. Zuber, M. Ucko, D. Angel, and H. Gordin. 1996. Seaweed biofilters as regulators of water
quality in integrated fish-seaweed culture units. Aquaculture 141: 183- 199.
In this article, Neori et al. examined the integrated culture of fish and seaweed on water quality in
landbased mariculture system. They recirculated seawater between intensive fishponds and
seaweed ponds. They observed that seaweed removed most of the ammonia excreted by the fish.
Water-quality parameters (DO, NH 4 -N, pH and phosphate) remained stable and within safe limits
for the fish during experimental period. Therefore, they concluded that their results provided a
practical solution to major management and environmental problems of land-based mariculture.
