“…Methods used for such processes are described in detail in Borowitzka & Borowitzka (1988) and Richmond (1986). Comparison of the economics of algal mass culture versus algal hatchery rearing reveals that large scale pond production is much less expensive ; cost estimates range from $1 .5/kg for Scenedesmus (De Pauw et al ., 1984) to $9/kg for Chlorella (Soong, 1980) .…”

“…Hatchery production has been identified as a major bottleneck to many aquaculture processes, as larval food cultivation is expensive, and a nutritionally balanced diet may be difficult to achieve (De Pauw et al, 1984). For example, De Pauw et al (1983) calculated that the cost of algal production when suitable natural blooms are available is US$4-23/kg dry wt, depending on the season .…”

Recent progress in the use of processed microalgae in aquaculture

Mass-cultured algal biomass has been tested as a food source for a number of aquaculture animals because of its low cost and convenience. This paper reviews the results of nutritional studies on processed microalgae with respect to mollusc, crustacean, rotifer and fish culture . Research using species of Spirulina, Chlorella, Scenedesmus and other mass-produced algae indicates that microalgae can be an effective dietary component provided that processing, diet formulation and presentation requirements are met . Processed microalgae can be used to correct specific dietary deficiencies in artificial diets . Our research found that the growth and pigmentation of marron, Cherax tenuimanus (Decapoda, Crustacea), can be significantly enhanced by the incorporation of Dunaliella salina in its artificial diet . Likewise, rainbow trout, Oncorhynchus mykiss, were pigmented by Haematococcus pluvialis .

The importance of dietary 20:5n‐3 (EPA), 22:6n‐3 (DHA) and 20:4n‐6 (ARA) for growth, survival and fatty acid composition of juvenile cockles (Cerastoderma edule) was investigated. Cockles of 6.24 ± 0.04 mm and 66.14 ± 0.34 mg (live weight) were distributed into three treatments where live microalgae diets were fed constantly below the pseudofaeces production threshold, for three weeks. Diets had distinct fatty acid profiles: high EPA (53% Chaetoceros muelleri + 47% Pyramimonas parkeae), no DHA (47% Brachiomonas submarina + 53% Tetraselmis suecica) and low ARA concentrations (73% P. parkeae + 27% Phaeodactylum tricornutum). Growth was positively affected by high EPA and low ARA diets, whereas no significant growth was observed for the no DHA diet. High mortality of cockles fed no DHA diet raises questions about its suitability for cockles. In balanced diets with EPA and DHA, lower concentrations of ARA do not limit growth. The impact of dietary fatty acids was evident in the fatty acids of neutral and polar lipids of cockles. In polar lipids of all cockles, there was a decrease in EPA, in contrast to an increase in DHA. The combination of EPA and DHA in a live microalgae diet was beneficial for the growth and survival of juvenile cockles.

“…Of the over forty different microalgal species currently cultivated as aquaculture feeds (De Pauw et al 1984), nearly all have been isolated from marine habitats. Marine strains of Chlorella and small flagellates from genera such as Dunaliella, Tetraselmis, Monochrysis, and Zsochrysis have been cultivated as food for oyster spat (Langdon and Waldock 198 1;Rornberger and Epifanio 1981;Epifanio 198l), larval fish (Spectorova and Doroshev 1976;Scott and Middleton 1979;Spectorova et al 1982), and larval marine shrimp (Simon 1978;Mock et al 1980).…”

Potential of New Strains of Marine and Inland Saline‐Adapted Microalgae for Aquaculture

Several problems currently limit the relibility of algal cultivation systems for the production of aquaculture feeds. Many of these problems may be eventually solved through research in culture system design and operation. However, research into the isolation and development of new strains of microalgae may also directly lead to improved system performance.Through a collection and screening program aimed at isolating microalgae tolerant to high light,high salinity, and high temperatures, we have been able to isolate several new strains with enhanced production potential (30-35 g/m*/d). The overall range of environmental tolerance exhibited by these strains may result in enhanced culture stability, leading to the high production rates. The estimated costs of producing strains with these high production rates range from $1.18 to $1.71 per kg (unharvested), depending on the size of the production system. Total production costs for harvested algae (15% solids algal cell paste) range from $1.63 to $2.45 per kg. The major costs for producing harvested algae include the cost of CO,, as well as capital and operating costs for the harvesting systems. I Corresponding author.
