“…Prior to its use, it was enriched with Super SelcoÒ (INVE Aquaculture, Dendermonde, Belgium) in one L tanks for six hours at a concentration of six mL L −1 . Enrichment period was chosen to avoid both FA autoxidation and FA retroconversion by Artemia (McEvoy et al, 1995;Nieves-Soto et al, 2021). Supporting this choice, preliminary observations indicated a significant increase in EPA and DHA percentage within six hours, as it was further confirmed by results herein (see "Foods of different source").…”

Finding new alternatives to traditional live preys such as Artemia and rotifers, which do not always promote optimal fish growth and survival, is required for the successful aquaculture of highly specialized predatory species, including seahorses. The present study assessed the nutritional value of an interesting marine amphipod (Parhyale hawaiensis), and evaluates through a feeding trial its potential use as a natural prey for 10-months lined seahorse, Hippocampus erectus. P. hawaiensis showed high levels of valuable lipids (20.4–26.7% on dry matter basis) and polyunsaturated fatty acids (PUFAs) ( 26.4–41% of total FAs), including the long-chain PUFAs (LC-PUFAs) arachidonic acid (ARA) (2.9–7.7%), eicosapentaenoic acid (EPA) (4.3–6.5%) and docosahexaenoic acid (DHA) (2.1–6.2%). A comparison between wild-captured and cultured amphipods revealed a significant improvement of the amphipod FA profile in terms of DHA%, total omega-3 (n3) FAs and n3/n6 ratio when employing both a conventional amphipod culture based on a commercial shrimp diet, and, to a lesser extent, a large (3,500 L) biofloc system. Seahorses fed with frozen/wild amphipods, either singly or in combination with Artemia enriched with Super Selco® (INVE Aquaculture, Belgium) for 57 days, substantially improved seahorse growth and FA profiles in terms of ARA, EPA and DHA%, including indices associated to marine sources, such as Σn3 and n3/n6, compared to a diet based solely on enriched Artemia. These results support the use of marine amphipods as an alternative food organism for juvenile H. erectus and suggest a potential use for general marine aquaculture.

“…El agua de mar fue filtrada hasta 1 µm, y la temperatura se mantuvo a 28°C mediante el uso de un calentador y un termorregulador (FINNEX, HMO-50). Además, se mantuvo con burbujeo intenso desde el fondo el recipiente, con la finalidad de mantener suspendidos los quistes (17). Al cabo de 18 h de incubación de los quistes; los nauplios fueron cosechados e inmediatamente se inactivaron con agua dulce a 60°C, y finalmente fueron conservados -20°C para su posterior utilización como alimento, el cual tuvo un tiempo no mayor a 72 h (3).…”

Objetivo. Evaluar el efecto de dietas tradicionales (Thalassiosira weissflogii y nauplios de Artemia) y otras dos alternativas (no tradicionales) a base de microalgas y rotíferos sobre la supervivencia, el desarrollo y crecimiento de larvas nauplio V (NV) hasta el día de cambio a postlarvas (PL1) de camarón Penaeus vannamei. Materiales y Métodos. Se realizaron dieciséis réplicas (unidades experimentales) para cada una de las tres dietas utilizadas. Las larvas se colocaron en contenedores de 12 L a 35 ups, 30°C y una densidad de 200 larvas/L. La supervivencia, etapa del desarrollo y el crecimiento se determinaron al inicio, cada 24 h y al final del experimento (PL1: día 8). A los datos obtenidos se les aplicó un ANOVA de una vía. Resultados. La dieta no tuvo influencia (p>0.05) sobre supervivencia y el peso. La supervivencia osciló entre 30.4% (dieta alternativa B) y 28.5% (dieta tradicional A). El desarrollo, longitud y peso más bajo a PL1 fue encontrado con la dieta tradicional (6.71; 3.53 mm; 58.37 µm/organismo) en comparación con las dietas alternativas suministradas B y C (6.86-6.76; 3.79-3.82 mm; 60.7-65.0 µm/organismo). Conclusiones. La alimentación más adecuada para la supervivencia, desarrollo y crecimiento larval se obtuvieron con las dietas alternativas no tradicionales (B y C) compuestas de rotíferos.

“…The particular abiotic conditions, such as salinity, and the optimal timing of the feeding periods may also be influential (Teixeira, 2004), thus warranting further research. Concerning artemia, further research aiming at finding the optimal time for their harvest may enable to circumvent its FA profile shortcomings (Nieves-Soto et al, 2020).…”

The microalgae Aurantiochytrium sp. (AUR), Isochrysis sp. (ISO), and Nannochloropsis sp (NAN) were studied as possible alternative feeds to well established commercial compound feeds for both rotifers (Brachionus plicatilis) and Artemia franciscana. Fatty acid (FA) composition -relative (in % of total FAs) and absolute (in mg/g dw)was determined in order to assess their potential for providing essential FAs. The FA profiles showed relevant differences between the four feeds (compound feed and the three microalgal species), but less stark than in the feeds themselves. Whereas Isochrysis sp. was relatively rich in DHA and poor in EPA, 18.6 AE 1.7% vs 0.6 AE 0.0%, respectively, Nannochloropsis sp. had the opposite pattern, 0.2 AE 0.3% vs 28.3 AE 0.7%. Aurantiochytrium sp. was rich in DHA (19.1 AE 0.2% corresponding to 89.8 AE 0.2 mg/g dw), but posed difficulties as a feed for both rotifers and artemia, given its low lipid incorporation and, in particular, poor DHA deposition. Rotifers fed the compound feed had the best combination of n3 PUFA levels (22.1 AE 0.1 mg/g dw), DHA contents (13.6 AE 0.4 mg/g dw), and DHA/EPA ratios (~3), being rotifers fed AUR and ISO feeds second best. Hence, these microalgae may deserve to be further explored as potential sources of specific FAs in rotifers and artemia.
