“…In this sense, the search for microalgal diets with high nutritional value for larval development of bivalve molluscs is one of the major steps to establish a protocol for spat production (Rico‐Villa, Le Coz, Mingant, & Robert, 2006; Uriarte & Farías, 1999), particularly due to the lipid‐rich diets are beneficial for larval growth. The importance of polyunsaturated fatty acids like 20:5(n − 3) and 22:6(n − 3) on the larval cultivation of molluscs has been shown in some bivalves, that is Crassostrea gigas (Langdon & Waldock, 1981), Ostrea edulis (Labarta, Fernández‐Reiriz, & Pérez‐Camacho, 1999), Mytilus galloprovincialis (Sánchez‐Lazo & Martínez‐Pita, 2014), Perna perna (Aarab et al, 2013) and Nodipecten nodosus (Sühnel, Lagreze, Zanette, Magalhães, & Ferreira, 2012). Another important fatty acid on molluscs larval development is the 20:4(n − 6) which has also been associated with higher growth rates, survival and less stress (Pernet, Bricelj, & Parrish, 2005).…”

Monoalgal and bialgal diet were tried in 2 stages of larval development of Striostrea prismatica: phase I from mixotrofic to early umbonated veliger larva and phase II until eyespot larvae. The monoalgal diets in phase I were Tisochrysis lutea, Pavlova lutheri and Nannochloropsis sp. In phase II, Tetraselmis suecica, T. chuii, Chaetoceros gracilis and Ch. muelleri were incorporated. The bialgal diets (combination of P. lutheri + Ch. gracilis in proportions 1:3, 1:1 and 3:1) were chosen according to the results of the monoalgal trials and were evaluated against the classic diet = control (T. lutea + Ch. gracilis). The microalgae size and their fatty acid composition were determined. We recommend the combination T. lutea + Ch. gracilis, initially using T. lutea for mixotrophic larvae (6 days Post Fertilization‐PF), then incorporating Ch. gracilis in a ratio of 1:1 until completing phase I (8–10 PF). In phase II, the ratio should change to 1:3 until larvae with eyespot are obtained (18–20 PF). Suggestions were based on the higher demand for DHA in initial larvae and the need for EPA from the early umbonated phase. Finally, as a third experiment, microsubstrates (pieces of shells, sandpaper, polycarbonate and ground rubber) were evaluated to promote the settlement of pediveliger larvae. A settlement of 20% was obtained in pieces of shells of the same species. We consider that the settlement technology has not been optimized; therefore, evaluations directed at the behaviour of the species are recommended.

“…With regard to essential fatty acids, bivalve species have been reported to require dietary sources of polyunsaturated fatty acids (PUFA), such as docosahexaenoic acid (DHA; 22:6n‐3) (Cheng et al, 2020; Farías, & Uriarte, 2006; Langdon, & Waldock, 1981; Sühnel et al, 2012), eicosapentaenoic acid (EPA; 20:5n‐3) (Farías et al, 2003; Sühnel et al, 2012), arachidonic acid (ARA; 20:4n‐6) (Pernet, & Tremblay, 2004) and docosapentanoic acid (DPA = 22:5n‐6) (Milke et al, 2006); Pernet et al, 2005). Besides promoting growth, PUFAs are an energy source, a component of cell membranes, and act as precursors for biochemicals involved in the immune response (Fritsche, 2006).…”

“…Although several studies have examined supplementation (Langdon & Waldock, 1981; Sühnel et al, 2012) or replacement (Adams et al, 2013; Langdon & Önal, 1999; Pérez‐Camacho et al, 1998; Sühnel et al, 2014, 2015) of live microalgae in diets for bivalve molluscs, there is still a need for less expensive alternative feeds (Luzardo‐Alvarez et al, 2010). Total or partial replacement of live microalgae by a low‐cost alternative food source may decrease hatchery and nursery production costs, resulting in more profitable commercial operations.…”

Owing to its high nutritional value and widespread availability, the legume alfalfa Medicago sativa (Linnaeus, 1753) is a possible feed for aquatic animals. In this study, a dried alfalfa chloroplast (DAC) product supplied by Virentia Inc., Quebec, Canada, was evaluated as a partial or total replacement for live microalgae (LM) in diets for juveniles of Perna perna and the Mesodesma mactroides—two species with high aquaculture potential in Brazil. In addition, trials were conducted with Venerupis philippinarum, a species commonly used in global aquaculture. Nine diets containing different ratios (based on dry weight) of live microalgae (Chaetoceros neogracile and/or Isochrysis galbana) and DAC were evaluated. With all three bivalve species, additions of DAC to partial microalgal rations increased final dry and organic weights, compared with those provided with partial algal rations alone. M. macrooides and P. perna appeared to utilize DAC to a greater extent than V. philippinarum as indicated by the higher final organic weights obtained by these two species when larger fractions of LM were substituted with DAC. Overall, the results of this study indicate that DAC supplements can be useful in supporting mussel and clam tissue growth when algal feeds are limited or unavailable.

“…Marine bivalves undergo a seasonal cycle of energy storage and utilization (Sühnel, Lagreze, Zanette, Magalhães & Ferreira ) that is linked to the progress of sexual maturation, promoting a highly variable competition for energy which develops between somatic process (growth, metabolism, maintenance) and the reproductive process (Lubet ). The gonadal development of bivalve was considered as the key parameter of the sexual maturation process ( e.g .…”

Broodstock conditioning of the Portuguese oyster (Crassostrea angulata, Lamarck, 1819): influence of different diets

et al. 2016

The Portuguese oyster Crassostrea angulata shows great potential in oyster farming. The conservation of pure populations of this species is important for production diversification and biodiversity preservation. In this way, the zootechnological development for seed hatchery production is extremely important. Broodstock conditioning is a key step in the process of rearing bivalves in a hatchery. Many factors regulate the reproductive cycle, being food one of the most important ones. To evaluate the effect of different diets on C. angulata reproductive performance, broodstock were conditioned with different food regimes formulated fundamentally by flagellates (Diet 1 – Pavlova lutheri and Isochrysis galbana clone T‐ISO; Diet 2 – P. lutheri, T‐ISO and Skeletonema costatum) and constituted fundamentally by diatoms (Diet 3 – S. costatum and Chaetoceros calcitrans; Diet 4 – P. lutheri, S. costatum and C. calcitrans). During conditioning, samples of oysters were collected to evaluate condition index, gonadal development and biochemical composition. At the end of the conditioning period, oysters were induced to spawn to evaluate reproductive output (fecundity, fertilization rate and D‐larvae development). The diets had an impact on the gametogenesis process, energy storage and reproductive output performance, being the best results those obtained in broodstock fed with the diatoms‐predominant diets. However, those fed with diets majority flagellates had an unsuccessful performance. Holistic approaches incorporating all results in this study reveal and reinforce the idea that the diatom species used presented the nutritional requirements to C. angulata broodstock, being essential in the conditioning phase.
