“…The improvement of length and weight of L. ramadalarvae fed on GW+R enriched with N may be due to rotifer fed on micro algae, Nannochloropsis oculata, which complete benefits of nutrients. These results were matching with Watanabe et al(2016). He mentioned that the larval performance of red porgy, Pagrus pagrus was improvement in growth and survival, when feeding on rotifer enriched by microalgae N. oculata or Tetraselmis chuii.In addition, Thépot et al(2016) reported that the barramundi, Lates calcarifer larvae were fed on rotifers enriched with N. oculata and Chlorella vulgaris give better growth, faster development and higher stress resistance.…”

“…The need to provide adequate dietary levels of essential fatty acids (EFA) for early developing fish with unusually high growth rates and large developmental demands is undoubtedly one of the highest priorities in larval rearing.A common practice for rearing marine fish larvae in captivity is to feed rotifers for several days or weeks gradually switching them over to Artemia nauplii and finally weaning them onto a dry feed. As rotifers and Artemia are naturally deficient in HUFAs, it is necessary to enrich these live feeds with essential fatty acids prior to offering them to the larvae (Conceiçãoet al, 2010 andWatanabe et al, 2016). Enrichments frequently employed to enhance the fatty acid composition of prey items include live microalgae, microalgae paste and lipid emulsions that include various marine fish and/or PUFA oils.…”

Keywords:Liza ramada growth performance Brachionus plicatilis Nannochloropsis oculata Live foodThe feeding success of Liza ramada larvae at early developmental stages depends on the provision of suitable food and rearing environment and on the visibility and adequate density of the prey. In the present study, the suitability of the marine enriched rotifers, Brachionus plicatilis as a starter food followed by enriched Artemia nauplii and their effects on the growth performanceand survival ratewere investigated for rearing of Liza ramada larvae.Induced spawning of mature Liza ramada breeders was done to produce the larvae. After hatching, the larvae were stocked at a density of 20 larvae/l in 50-l glass aquaria, under different feeding conditions for three periods; green water conditions; with Nannochloropsis oculata (2.5×10 5 cells/ml) for 7 days, rotifers (8-10 individuals/ml) for 28 days and Artemia salinanuplii (4-6 individuals/ml) for 28 days. Four groups were applied for both rotifers and Artemia; green water conditions with rotifers or Artemia enriched with N. oculataor yeast and clear water conditions with rotifers or Artemia enriched with N. oculata or yeast.The results showed improvement in growth and survival rates of Liza ramada larvae fed on green water with Brachionus plicatilis or Artemia salina enriched with N. oculata at the end of 7 th day, 35 th day and 63 rd day post-hatching, respectively. This indicates that the algae N. oculata is essential not only for feeding requirement of larvae at first feeding but also for water quality improvement. Larval wet weight varied significantly between the treatments. However, the final length of the larvae did not vary significantly between the treatments.In conclusion, the presence of green algae Nannochloropsis oculataduring Liza ramada larval rearing, in water or as enrichment media for live food, is essential not only for growth performance but also for raising survival rate.

“…Several commercial manufacturers now advertise microdiets dedicated to replace live feeds (mainly Artemia nauplii) or at least to advance weaning from live feeds. Such feeds have been compared (Curnow, King, Bosmans, & Kolkovski, 2006;Curnow, King, Partridge, & Kolkovski, 2006) and are increasingly used for commercial aquaculture species (e.g., Katan et al, 2016;Watanabe et al, 2016) but also for experimental zebrafish (Farias & Certal, 2015). However, the suitability of such standard agglomerated commercial microdiets has rarely been tested, respectively, been published for European whitefish (Leithner & Wanzenböck, 2015).…”

The suitability of two agglomerated commercial microdiets ("Gemma micro ® " and "O.range ® " from now on called diet A and diet B) as a starter feed was tested on larvae of European whitefish (Coregonus lavaretus). Two strains (Baltic and Alpine) were tested in a 60-day experiment under ambient cold-water conditions (average 7.6 ± 1.9°C). The experiment was carried out in 400-L PVC tanks with a stocking density of 5,000 larvae per tank. Samples were removed weekly to determine growth, survival and feed acceptance, in addition to water quality. Striking differences between the feeds and different strains were observed. For one diet, growth and survival were distinctively higher in strain 1 compared to strain 2, where it was invariably low with both diets. For the second diet, growth and survival in strain 1 were also low and similar to strain 2. Feed acceptance in strain 1 was found higher compared to strain 2.Final weights were significantly different with strain 1 being heavier; however, in terms of relative growth rate, no differences between strains were found. Strong differences in the performance in terms of growth, survival and feed acceptance of different strains of European whitefish became apparent. Furthermore, the rearing of larvae exclusively on standard agglomerated commercial microdiets under cold-water conditions is possible, but not every microdiet is suitable.

“…Formerly, the effect of EN Artemia nauplii has not been evaluated in fish, especially ornamental fish. Although there are several studies on the effect of enriched Artemia nauplii with fatty acids on Latris lineata (Bransden, Battaglene, Morehead, Dunstan, & Nichols, ), Sparus aurata (Monroig et al, ), Hippoglossus hippoglossus (Hamre & Harboe, ), S. senegalensis (Boglino et al, ), S. lucioperca (Lund, Skov, & Hansen, ), Pagrus pagrus (Watanabe et al, ), Argyrosomus regius (Campoverdea & Estevez, ). Our results showed that growth and nutritional performance of green terror cichlid larvae increased with enrichment of Artemia nauplii, so the group fed 10 EN and 5 EN had significantly higher total weight, WG %, SGR and fish fed 25 EN had significantly higher FCE, PER and NPU, compared to other groups.…”

The effects of feeding on a commercial diet and lecithin‐enriched (EN) Artemia franciscana nauplii for improving co‐feeding strategies of Neotropical green terror cichlid (Aequidens rivulatus) larvae were conducted. For this purpose, eight groups of fish in triplicates were assigned with two different diets (unenriched Artemia [UN] and EN Artemia) and four feeding regimes (1, 5, 10 and 25 days feeding with UN and EN diets and then a 10% daily replacement Artemia nauplii with commercial diet). The crude lipid (21.4%) and total polar lipid (12.96% of total crud lipid) levels significantly increased in enriched Artemia nauplii (p < 0.05). The highest amount of saturated fatty acids (SFA) were in enriched and UN Artemia nauplii (41.74% and 49.64% respectively) but the highest level of monounsaturated fatty acids (MUFA) (25.69%) and polyunsaturated fatty acids (PUFA) (49.11%) were obtained in commercial diet. Growth performance of fish fed 10 EN and 5 EN had significantly higher values of total weight (120.67, 120.31 mg), %WG (584.48, 580.50%) and SGR (7.69, 7.67%) respectively (p < 0.05). Nevertheless, fish fed 25 EN had significantly higher FCE (190.4%), PER (3.95) and NPU (202.5), in comparison with other groups. In terms of body composition, the EN Artemia nauplii led to increased lipid contents in 25 EN, 10 EN and 5 EN treatments. In conclusion, the results of this study revealed that feeding regimes of 10 EN and 5 EN could improves survival and growth performance of Neotropical green terror cichlid, A. rivulatus larvae.
