“…Mortality of the canola oil treated fish was significantly lower than unenriched nauplii fed fish supporting the results of Limanda ferruginea (D. H. Storer) [24], Peterophylum scalare (Schultze) [25] and Oncorhynchus mykiss (Walbaum) [26]. Akbary et al [26] concluded that survival rate of rainbow trout larvae fed with enriched Artemia (HUFA + vitamin C) during 29 days of testing (96%) is higher than larvae fed unenriched nauplii (84%) and larvae were fed with commercial food (67%).…”

The effect of canola oil enriched Artemia (Leach) nauplii on growth, survival, resistance to environmental stresses of temperature and oxygen deficiency and fatty acid composition in severum fish, Heros severus (Heckel), larvae were investigated. The larvae (average weight 3 mg ± 0.83) were fed 4 times daily starting at the onset of exogenous feeding for 18 days. Triplicate groups of fish were offered one of two treatments: 1) newly hatched Artemia (Leach) nauplii (unenriched) and 2) canola oil enriched Artemia (Leach) nauplii. Then all groups of fish were switched to the commercial diet for an additional period of 18 days. Statistical analysis of growth after 18 days and at the end of the experiment (36 days), showed that the highest specific growth rates (9.65% ± 0.3), (17.44% ± 0.31) the average weight (17 mg ± 0.95), (65.2 mg ± 0.53) were observed in treatment 2 respectively, but there was no significant difference in survival rate between treatments. The best result of resistance to oxygen deficiency (5 min) was observed in larvae reared on treatment 2 with 75.67% ± 0.66 after 36 days. Result of temperature stress showed no significant difference between treatments. The larvae were also found to convert n-3 fatty acids to EPA and DHA.

“…Recent research has focused on the efficacy of using alternative preys, such as ciliates, Barnacle nauplii, nematodes and copepods (alone or in conjunction with traditional prey items), to overcome dietary nutritional deficiencies [33][34][35]. Copepods are considered the most promising alternative live prey to feed marine fish larvae, due to a preponderance of phospholipids and ratios of DHA: EPA: ARA [36,37] that closely resemble the natural diet of the larvae.…”

The Consumption of DHA during Embryogenesis as an Indicative of the Need to Supply DHA during Early Larval Development: A Review

The establishment of an adequate larval diet for crustacean and fish often involves a series of time-consuming and expensive trial and errors. Despite being nutritionally poor, rotifers and Artemia are the most commonly used preys in larviculture. Whether (and to what extent) the prey needs to be enriched with essential fatty acids differs from species to species. We hypothesized that the DHA content of a newly spawned eggs and its consumption through embryogenesis can be a good indicator of the need to enrich the prey with DHA. In order to assess this hypothesis, we performed a search in the scientific literature and compared DHA consumption through embryogenesis with larval culture success with unenriched and DHA-enriched Artemia nauplii, respectively a prey poor and rich in DHA of fish and crustacean. Data available from previously published studies suggests that, higher the consumption of DHA during embryonic development, greater the requirement of a diet rich in DHA during early larval development; and when, although present, DHA is not consumed during embryogenesis, larvae seem to be able to successfully develop with diet poor in DHA (i.e. using solely their reserves). Further studies will be necessary to better validate this hypothesis, but if confirmed, it may allow a reduction of time and costs associated with the establishment of an adequate larval diet.

A new species of Apocyclops Lindberg (Cyclopoda: Cyclopoida: Cyclopidae) is described based on specimens collected from marine waters of Karwar, Karnataka, India. At present, there are 11 valid and accepted species excluding one extinct species (fossil) in this genus which are widely distributed in fresh and brackishwater areas in the tropics and subtropics. Five valid species of Apocyclops are reported from the Asian region, including two species from India. The new species is closer to the previously reported Indian species, A. royi (Lindberg) and A. dengizicus dengizicus (Lepeshkin). Apocyclops cmfri sp. nov. differs from these in the size of caudal rami, in the characteristic shape of disto-medial part of coxa and basis of first to fourth pleopods (P1-P4) and in the presence of a single broad spinous expansion with a pointed tip in between exopod and endopod in basis of P1 to P4. Only one terminal spine is present in the second segment of endopod of P1. In P2 to P4, both exopod and endopod terminate in a spine and a seta of almost equal size. Maxillule highly dentate and maxilla basis form a large dentate claw with inner serration. All these characters form distinct identification features of the new species in comparison with the 12 accepted species under the genus. A key to all the species of the genus including the newly described species is proposed here. Molecular identification of the new species was carried out by mitochondrial cytochrome c oxidase 1 (CO1) gene sequencing and the sequence was submitted to NCBI, GenBank. Genetic differentiation and divergence between A. cmfri sp. nov. and species belonging to other closely related genera; Thermocyclops, Mesocyclops and Eucyclops were compared using CO1 gene sequences. The new species belonging to Apocyclops showed significant divergence from Apocyclops borneoensis with K2P value of 10.2% and from species under the genera Mesocyclops, Thermocyclops and Eucyclops with K2P values of 26.6, 27.5 and 34.9% respectively.
