The southern surf crab Ovalipes trimaculatus (de Haan, 1833) presents a high potential for aquaculture. In this study, we analyze the benefits of different dietary treatments on its molt success and fitness of larval stages. Artemia persimilis nauplii were enriched with monospecific (Nannochloropsis oculata, Tetraselmis suecica, Dunaliella salina, Isochrysis galbana and Chaetoceros gracilis) and multispecific (Mix) microalgal diets twice a day over a 48-h period. Mean total length (TL), growth instar number (I) and gut fullness rate (GFR) of nauplii showed significant differences between dietary treatments at several sampling times, optimal results being observed in those providing Mix. Artemia nauplii grown under most experimental dietary treatments reached the capture size limit for Ovalipes trimaculatus zoea I (700 µm) within 24 h. After that time interval, Mix-enriched nauplii were amongst those with higher protein contents. Ovalipes trimaculatus zoea I fed on Artemia nauplii en...

The survival and growth of Penaeus semisulcatus postlarvae fed Artemia nauplii or rotifers, Brachionus plicatilis, were studied in a small-scale bioassay system. Shrimp larvae at the nauplius 6 substage were cultured in 1-l cones at a density of 100/l, with daily medium exchange. In the first set of experiments shrimp from the zoea 2 (22) versus zoea 3 (23) substages were fed rotifers at increasing densities. Dry weight of postlarvae fed 20 or 30 rotifers per ml was higher than that of larvae fed 10 or 40 rotifers per ml (P < 0.05). No differences were found when postlarvae were fed from the 22 versus the 23 substage. In the second series of experiments Artemia were given at increasing densities to shrimp from the Z2,23, or mysis 1 (Ml) substages. Dry weight increased as prey concentration rose to 9 per ml and decreased when feeding was postponed to 23 or Ml (PcO.05). The third experiment compared regimes in which larvae were fed Artemia or rotifers alone, or rotifers from 22 followed by Artemia from 23, Ml or M2. Postponing or eliminating Artemia addition resulted in decreased postlarval dry weight (PcO.05). High survival can be achieved with rotifers, but energy intake is apparently reduced as dry weight is lower. Thus Artemia nauplii alone may be a superior food for mass culture of penaeid larvae.

Shrimp farming is one of the most important aquaculture and economically lucrative practices of maritime countries. Providing a Specific Pathogen Free (SPF) shrimps to the farmers is a big challenge that must be addressed to meet the demand. In general, microalgae are utilized in aquaculture as a live feed for the shrimps. However, their importance in the attenuation of negative impacts of pathogenic microbial load, eutrophication and promotion of shrimps growth has to be delineated by experimental investigations to justify the above specific pathogen free shrimps. The present study was carried out to investigate the feeding of five different microalgae and algae enriched Artemia salina. Nauplii on digestive enzyme activity, growth, survival rate, microbial load on Penaeus monodon and Litopenaeus vannamei from zoea to post larvae (20 stages) and other water quality. Microalgae such as Isochrysis galbana, Cheatoceros calcitrans, Tetraselmis sp., Chlorella sp. and Nannochloropsis sp. were obtained from AMET Microbial Culture Collection Centre, Department of Marine Biotechnology, AMET University. Penaeus monodon and Litopenaeus vannamei at PL 20 stage showed maximum protease and amylase (digestive enzyme) activity, maximum length and survival rate when fed with Artemia salina nauplii enriched with C. calcitrans followed by Chlorella sp. On studying the water quality parameters such as, pH, temperature, salinity, dissolved oxygen and ammonia it was found better in tank II where the shrimps were fed with Artemia salina enriched with C. calcitrans. Regarding the vibrio load at different stages of P. monodon and L. vannamei larvae and cultured water it was comparatively lower in tank II, where the shrimps were fed with Cheatoceros calcitrans and enriched Artemia salina than other groups. It is concluded that, the use of Cheatoceros calcitrans and enriched Artemia salina will reduce the potential negative impacts in the environment and promote production of shrimp larvae in hatcheries and fetch benefits to local economies.

The nutritional value of nauplii and metanauplii I of Artemia enriched with microalgae as food for freshwater prawn larvae (Macrobrachium americanum) was tested. The larvae were fed with three different diets consisting of Artemia nauplii (D 1), Artemia metanauplii I enriched with Tetraselmis suecica (D 2), and Artemia metanauplii I enriched with Chaetoceros calcitrans (D 3) from zoea (Z) II. Growth showed differences since the third week, and the highest and lowest growth was observed with D 3 and D 1 , respectively. The first metamorphosis to post-larvae appeared with treatment D 3 at 9 weeks. Survival showed differences at the first week with D 1 and D 3 treatments, and D 2 showed the best survival up to week 4. From the sixth week to the end, treatment D 3 reached the highest survival.

Shrimp farming is one of the most important aquaculture and economically lucrative practices of maritime countries. Providing a Specific Pathogen Free (SPF) shrimps to the farmers is a big challenge that must be addressed to meet the demand. In general, microalgae are utilized in aquaculture as a live feed for the shrimps. The retention time of food in the gut is lower than in mysis and postlarvae, while feces production is high. Therefore, knowledge of the optimum level of protein, lipids and carbohydrates would be effective in reducing feed costs and water pollution. The types and levels of these nutrients in the diet have been shown to affect the growth. Thus, present study focused to examine the biochemical profile of Penaeus monodon and Litopenaeus vannamei shrimp culture at different stages from Z3 to PL20. From the results, it has proven that the biochemical concentration will be vary (Protein 16.06±0.582 to 21.98±0.81, Carbohydrate-3.82±0.576 to 8.32±0.649, Lipid-11.22±0.322...

The crustaceans larviculture has been based on live food although the production ofthis food is expensive, it requires toward the search of live foods substitutes, artificial diets, microparticulate or microencapsulated are used. The present study was designed to examine the substitution, at least partial, of Artemia nauplii for artificial food in the Litopenaeus schmitti larviculture. An artificial food was elaborated using as additive Spirulina me al, and the zoothecnical indexes were evaluated: Growth, development index and survival. The chemical score to evaluate the protein quality ofthe foods is used. In the shrimp Hatchery YAGUACAM, Cienfuegos, Cuba, a randomized design was developed, with five treatments and three replicates, where they were substituted total and partially the rates of Artemia nauplii for the dry food. When concluding this study applied different statistical tests that allowed to end up concluding that: The survival was not affected when substituting 100% of...

Replacement of live feeds with alternate food sources is of major importance in commercial shrimp hatcheries. In this study, partial and complete replacement of live microalgae and Artemia nauplii with microalgae pastes and inert feeds is reported in the larval rearing of the brown shrimp Farfantepenaeus aztecus. Five different experimental feeds were used for each live food replacement study. Partial replacement of live microalgae using Chaetoceros 1000 bPremium FreshQ Instant Algaek paste and Liqualifek liquid larval feed showed survival rates similar to a control feed, however, postlarvae mean dry weight and length were significantly less than the control. Use of other replacement feeds, Epifeedk liquid larval feed, Zeiglerk E-Z Larvae liquid feed, and Zeiglerk Z-Plus feed, yielded inferior results compared to the control feed. Statistical analysis of results from the live Artemia nauplii replacement study indicated that larval shrimp fed a control feed had significantly greater survival, mean PL length, and mean PL dry weight. The only exception was the partial replacement of Artemia nauplii using Liqualifek in which there was no significant difference in survival between the control and this treatment. Results indicated that although Liqualifek, Epifeedk, Zeiglerk E-Z Larvae, Zeiglerk Z-Plus and Zeiglerk E-Z Artemia feeds could serve as partial replacement of newly hatched Artemia nauplii in production of F. aztecus postlarvae. Significantly improved results can be expected when larvae are fed newly hatched Artemia nauplii (control diet) with no supplement.

Artemia are used intensively for slow feeding species like the green mandarinfish, Synchiropus splendidu s , however, the size and nutritional content of Artemia on their reproductive performance, requires determination. To investigate this, 12 pairs of 14-month old F1 progeny were maintained in glass aquaria containing 90L of seawater and fed twice daily on either: 1) adult Artemia (AA) at 3 individuals (ind.) L -1 ; 2) newly hatched Artemia (NHA) at 0.5 ind.mL -1 ; 3) mixtures of AA and NHA at a ratio of 2 ind.L -1 : 0.5 ind.mL -1 ; and 4) mixtures of AA and NHA at a ratio of 1 ind.L -1 : 0.5 ind. mL -1 , respectively. Maintained with dry Spirulina sp . , Artemia were enriched daily with microalgae mixtures, i.e ., either Tetraselmis gracilis and Isochrysis galbana or T. gracilis and Nanochrolopsis oculata . NHA contained higher protein and lipid levels than AA; the protein levels of AA fed mixed T. gracilis and N. oculata were high but their lipid levels were similar to that fed ...

The use of dried Artemia biomass meal as an exclusive feed for postlarval white shrimp (Litopenaeus vannamei) was compared with four commercial feeds and three crustacean meals in a series of trials. Postlarvae (PL1-PL6) were stocked at a density of 1.5-2.5/litres in 16 tanks (100 litres volume) and fed, ad libidum, five times a day, over 23-29 days. Feeding postlarval shrimp with dried Artemia biomass resulted in a significantly larger size than feeding with three of the commercial feeds, and the crustacean meals. There was no significant size difference observed in animals fed with Artemia biomass and the commercial 'Golden Pearls' feed for postlarvae, however the coefficient of variation among the size of the 'Golden Pearls' fed animals was significantly higher. The weight increase of animals fed with Artemia biomass was higher than in animals fed with all the tested feeds. The survival rate was not significantly different in animals fed with Artemia flakes from 'Salt Creek', 'Bio-Marine', 'Golden Pearls' and Artemia biomass, however the survival rate was significantly larger in animals fed with Artemia biomass than in animals fed with the crustacean meals and 'Artemac.' Results suggest that dried Artemia biomass is a well-suited feed for postlarval L. vannamei.

Newly hatched Coregonus maraena (Bloch) larvae reared in aquaria were observed during two trials in 2014 and 2015 for 42 and 34 days after hatching in order to determine the on-feeding effects of different feeding strategies on growth and survival. Feeds of commercial dry feed, live Artemia nauplii, frozen rotifers, and mixtures of these were compared. Larval whitefish were fed brine shrimp for up to 13 days beginning 4 days post hatch (dph). Whitefish larvae fed live Artemia for 8-9 h per day over a period of 10-12 days grew considerably larger (mean value of final total length (TL) 27.3-33.0 mm)) and were heavier (mean value of final body weight (BW) 112-165 mg)) than those fed dry feed, frozen rotifers, or Artemia for 3-6 days (TL= 22.6-30.2 mm; BW= 50-102 mg). The growth of larvae fed for 24 h solely on dry food was comparable (BW= 101 mg, TL= 26.6 mm) at 42 dph. Survival differed among groups (31-63%) and was highest for larvae fed dry food exclusively. Our results can improve ...
