“…The most important experiments in this field are those of Hidu and Ukeles (1964) with the larvae of Mercenaria mercenaria, and Masson (1977) and Cordero Esquivel and Voltolina (1996) with the larvae and juveniles of Mytilus galloprovincialis. Other authors have used heterotrophically cultured microalgae, especially the species T. suecica, as for example Laing et al (1990) with the larvae of Tapes philippinarum and Laing and Millican (1991); Laing and Gil Verdugo (1991); Laing and Millican (1992) and Curatolo et al (1993) with seed of the same species. All these experiments showed the need to add a certain proportion of fresh microalgae to the inert diets in order to achieve comparable growth rates to those of fresh diets.…”

“…Epifanio (1979) Urban and and Coutteau et al (1994) all describe substitutions of up to 50% of fresh microalgal diets with yeasts. Laing and Gil Verdugo (1991); Laing and Millican (199 1) and Curatolo et al (1993) substituted various proportions of fresh microalgae with dried microalgae. The proportion of fresh microalgae (20%) used in the present study was not large enough to achieve the same growth rates as with fresh diets, although there was a significant increase in growth rates compared with those of totally inert diets.…”

et al. 1997

This study evaluates the nutritional value of several species of freeze-dried microalgae used to feed the seed of Ruditapes decussatus. These microalgae were: Isochrysis galbana, clone T-ISO; Tetraselmis suecica; and Phaeodactylum tricornutum. The addition of antibiotics, kaolin and fresh microalgae to the freeze-dried diet was also evaluated, and a study was made of the nutritional value of one species of microalga in each of the four stages of preparation of the freeze-dried diet: culture; concentration; freezing and freeze-drying. Both physiological and biochemical criteria were used to evaluate the different diets: availability; acceptability; digestibility; and biochemical composition.The highest seed growth rate were achieved with a diet of Isochrysis, followed by Tetraselmis, whilst the growth rates achieved with a dried diet of Phaeodactylum were much lower. The differences observed between diets of Isochrysis and Tetraselmis were due to a greater ingestion of the cells of Isochrysis. The minimal nutritional value of Phaeodactylum appears to be related to the low digestibility of its cell wall. The growth rates of seed fed on a diet of dried microalgae were significantly lower than those achieved with fresh diets (Albentosa et al., 1996b) for each of the species of microalgae that were tested, and this appears to be related to the lower digestibility of the microalgae after they have been freeze-dried. The addition of antibiotic or kaolin to the freeze-dried diet did not result in a major increase of seed growth rates. The substitution of a small proportion of freeze-dried microalgae with fresh microalgae produced a significant increase in seed growth rates, although these were still lower than those obtained with a completely fresh diet. The loss of nutritional value of microalgae when they are freeze-dried may be due to some kind of process which occurs during freezedrying, altering the digestibility of the microalgae.

“…Microalgae production is one of the critical points in many hatcheries because it involves several factors of risk that makes it vulnerable (Okauchi 1991;Molina Grima et al 1994;Duerr et al 1998), further to represent, in some cases, more than half of the total production costs of the aquaculture organisms (Laing and Helm 1981;Fulks and Main 1991;Benemann 1992;Coutteau and Sorgeloos 1992;Borowitzka 1997;Cañavate and Fernándes-Díaz 2001). In the past decades, these problems have promoted many studies on the development of food sources alternative to live microalgae (fresh cultures), such as microparticulate diets (Amjad and Jones 1992), microencapsulated and inert food (Numaguchi and Nell 1991;Medina-Reyna et al 2005), lipid emulsions , yeasts (Nell et al 1996), bacteria (Douillet 1993;Douillet and Langdon 1993), and microalgae concentrates preserved by several techniques (Curatolo et al 1993;Cordero Esquivel and Voltolina Lobina 1996;Papandroulakis et al 1996;Albentosa et al 1997;Knauer and Southgate 1999;Brown and Robert 2002).…”

“…Several methods have been used to preserve the quality of concentrated cells during storage, mainly additives (Molina Grima et al 1994;Heasman et al 2000;Tzovenis et al 2004), lyophilization (Cordero Esquivel and Voltolina Lobina 1996;Albentosa et al 1997), spray drying (Curatolo et al 1993), freezing (Lubzens et al 1995;Papandroulakis et al 1996;Cordero and Voltolina 1997), and refrigeration (Nell and O'Connor 1991;Montaini et al 1995;McCausland et al 1999;Heasman et al 2001).…”

The present study was conducted to define a methodology to produce and store small-scale microalgae paste to be used in a mollusk hatchery. Microalgae were cultured in 500 L fiberglass tanks, under temperature of 20 6 2 C, Guillard f/2 culture medium, and continuous light intensity of 203-226 mmol photons/m 2 /sec. Cultures were centrifuged at 2000 g at the exponential growth phase. Microalgae cell quality after centrifugation and during storage was determined by analyses with Evan's blue stain and by counting the number of total marine bacteria. Treatments with and without additive were applied to the microalgae paste produced, which was distributed into 100 mL plastic containers, capped, and stored under refrigeration at 4 6 1 C. Results indicated that in the Chaetoceros muelleri paste, centrifugation did not damage the cells and the number of total marine bacteria reduced significantly from 2.9 3 10 6 to 8.3 3 10 5 colony-forming units per milliliter. Chaetoceros muelleri and Chaetoceros calcitrans pastes stored with addition of 0.1% ascorbic acid had a shelf life shorter than 2 wk. For the treatment without additive, results with Evan's blue stain showed that cells (99%) remained viable until the sixth week of storage for C. muelleri and seventh week of storage for Skeletonema sp. and C. calcitrans. The number of bacteria did not increase during storage for C. calcitrans and Skeletonema (P . 0.05). For C. muelleri, an increase in bacteria (P , 0.05) was observed after the sixth week of storage. This study demonstrated the feasibility to produce and store microalgae paste for a period of 2-8 wk, which allows it to be used as food source and also optimizes the use of microalgae cultured in laboratory.

This study describes for the first time the cultivation of Cerastoderma edule on a commercial scale. A protocol to grow F2 generation cockles was developed, which led to fine‐tuning experiments for broodstock conditioning and spat growth. Broodstock animals were conditioned with diets of Isochrysis galbana (T‐Iso) or Tetraselmis suecica, whereas a third group was not fed. The best diet, T. suecica, induced 12 females out of 100 animals to spawn a total of 3 380 000 eggs. The non‐fed group did not spawn. Cockle spat (4.9 ± 1.0 mm) grew best when given a mixed diet of C. muelleri, T‐Iso and Sceletonema costatum, or a mixture of P. tricornutum and S. costatum at a concentration of 240 cells μl−1 day−1, resulting in a tripling of their wet weight after 14 days. The impact of density, burrowing substrate and food availability on cockle spat growth (41 days old, 5.6 ± 1.2 mm) was studied for 11 weeks. Best results were obtained by culturing spat at ad libitum food conditions at 500 ind m−2, resulting in an average growth rate of 168 μm day−1, an average final size of 19.0 ± 1.9 mm and a total final biomass of 1040 g m−2.
