“…The microalgae C. vulgaris is widely used in toxicity tests, sensitive to several chemical agents common in aquatic environments (Rand et al 1995;Rai et al 2013;Kumar et al 2015;Expósito et al 2021), in addition to being part of the cladocerans diet (Nandini and Sarma 2003;Ismail et al 2019;Latib et al 2020). The species C. dubia and C. silvestrii are found, respectively, in temperate (Europe and North America) and neotropical (Brazil and Argentina) regions and used as test organisms in ecotoxicological evaluations (C. dubia andC.…”

Given the importance of metals in the contamination of aquatic ecosystems, studies are needed to assess the effects of these contaminants on aquatic organisms through different contamination pathways. Chromium (Cr) is a metal widely used in various industrial processes, considered a priority pollutant in several countries. In the present study, ecotoxicological tests were carried out with the microalga Chlorella vulgaris, evaluating the effects of Cr on cell density, pigment concentration, and biochemical composition. Additionally, the effects of chromium exposure on cladocerans (Ceriodaphnia dubia and Ceriodaphnia silvestrii) were investigated through three contamination routes: contaminated medium, contaminated food (C. vulgaris), and the combination of both situations (contaminated medium and food). The toxicity tests with cladocerans evaluated the metal effects on survival, number of newborn produced by female, and feeding activity. The results obtained demonstrated that 48 µg L-1 total dissolved Cr reduced cell density and increased protein, carbohydrate, and lipid content in C. vulgaris. The increase in the biochemical composition of microalgae upon exposure to Cr may have contributed to the non-observation of chronic toxic effects on daphnids in the treatment with contaminated food. A decrease of 31% and 26% in the number of C. silvestrii offspring was observed for the treatment with contaminated medium (35 µg L-1 total dissolved Cr) and associated treatment (35 µg L-1 total dissolved Cr and 3 × 10-14 g Cr cells-1), respectively. The importance of the Cr poisoning pathways and the difference in cladoceran species’ sensitivity to the metal were addressed.

“…The availability of different food sources for live feed enrichment is crucial in providing better quality in a large quantity of live feed sources for aquatic organisms (Kandathil Radhakrishnan et al, 2020; Yuslan et al, 2021a). There are many studies on the enrichment of live feeds focused on using only microalgae as the main and common food sources (Latib et al, 2020). Microalgae of the genus Nannochloropsis is a green alga that is frequently utilized as a feed in Malaysia's aquaculture sector (Zainal Abidin et al, 2020).…”

The copepod Oithona rigida can be used as a natural feed in rearing larvae of the mud crab Syclla olivacea. However, copepod is not readily obtainable due to their characteristics as seasonal zooplankton, causing limitation in using copepods. The objective of this study was to evaluate the nutrient transfer of enriched O. rigida in improving the growth development and survival of early‐stage mud crab (Scylla olivacea). The effects of different feeding regimes on the survival and development of S. olivacea larvae were studied in two phases of the crab larval development: Phase 1 (zoea 1 to zoea 2 stage) and Phase 2 (zoea 5 to megalopa stage). The feeding regimes were T1: O. rigida enriched with rice bran, T2: O. rigida enriched with Nannochloropsis oceanica, T3: O. rigida enriched with a mixture of rice bran and N. oceanica, and T4: Artemia. The results showed that rice bran (66.83 ± 2.25% protein and 21.98 ± 1.41% lipid) and N. oceanica (72.08 ± 2.02% protein and 18.09 ± 1.18% lipid) additives produced the best outcomes in terms of protein content and lipid content of O. rigida. A mixture of rice bran and N. oceanica (41.62%) as enrichment also improved the polyunsaturated fatty acids (PUFAs) content of O. rigida as compared with a mono diet applied such as rice bran (28.16%) and N. oceanica (31.35%). The average survival rate of S. olivacea from zoea 1 until megalopa shows that T3 (20.20 ± 1.97%) was higher than T1 (13.87 ± 0.90%), T2 (12.47 ± 1.14%) or T4 (3.13 ± 1.29%). In conclusion, improving the survival rate of crab larvae in commercial hatcheries by using precise early‐stage foods is fundamental to enhancing the seed production technology of mud crabs.
