“…LA, ALA, ARA, and EPA levels in H. scabra were compared with other sea cucumbers and fishes. LA has also been detected at high levels in other sea cucumber, S. chloronotus (12.87%), and the Nile tilapia, Oreochromis niloticus (20.90%) [27]. The levels of ALA found in whole body and body wall of H. scabra were low and found very low in other sea cucumbers at 0 -1.88% [3,5], and fishes at 0 -1.86% [27,28].…”

“…NA is found in sphingolipids, such as sphingomyelin in the myelin sheath of nerve fibers and in the white matter of animal brains [26]. NA was also found in other sea cucumbers at a much lower amount than in H. scabra, and was not detected in fishes [27,28]. NA supplementation is thought to improve neurological function [29] and enhance myelination in patients with demyelinating disease [30].…”

Background: Holothuria scabra is one of the most commercially important species found in the Pacific region. The sea cucumber extracts have been widely reported to have beneficial health effects. The aim of this study was to determine the nutritional compositions of H. scabra, and compare its important nutritional contents with that of other species.Methods: The sea cucumbers were dissected, sliced into small pieces, and then freeze-dried. The nutritional compositions, including proximate composition, amino acids, fatty acids, collagen, GABA, Vitamin A, C, and E of the whole body and body wall of H. scabra, were analyzed.Results: H. scabra contained a high quantity of protein (22.50% in whole body and 55.18% in body wall) and very low lipids (1.55% in whole body and 1.02% in body wall). The three most abundant amino acids found in both the whole body and body wall were glycine, glutamic acid, and proline. The main fatty acids found in the whole body were stearic acid and nervonic acid, and in the body wall were arachidonic acid and stearic acid. The whole body and body wall also contained high levels of essential amino acids, essential fatty acids, and collagen, in addition to moderate amounts of vitamin E and low amounts of GABA and vitamin C.Conclusions: The sea cucumber, H. scabra, contained high quantity of protein and very low lipid. It contained high essential amino acids, essential fatty acids, nervonic and arachidonic acids, and collagen, which also contained GABA, vitamin C, and vitamin E.Keywords: sea cucumber; Holothuria scabra; nutrition components; functional food

“…Similarly, Sudaryono [23] noted that A. pinnata inclusion in the diet of black tiger shrimp (P. monodon) reduced PER values. Additionally, Abou et al [29] recorded that PER progressively reduced from 0% to 50% substitution of fish meal with Azolla meal in Nile tilapia feeding.…”

“…This could be due to either poor absorption of the protein of supplementary A. pinnata by the fish or poor protein quality (amino acid composition). In a previous study, Abou et al [29] noted that FCR values rose from 0% to 50% substitution of Azolla filiculoides for Nile tilapia (Oreochromis niloticus L.). In contrast, Badwy et al [30] reported that up to 50% replacement of fishmeal with single-celled algae Chlorella spp.…”

Aquatic fern Azolla pinnata comprises significant high food value with a good proportion of protein, vitamins, and minerals. This study was carried out to examine the effect of fresh A. pinnata as a substitution of commercial fish feed (CFF) for Thai silver barb Barbonymus gonionotus. Post fingerlings of B. gonionotus were reared in five treatments, labeled T 1 to T 5 , by substituting 0%, 25%, 50%, 75%, and 100% protein of CFF with A. pinnata protein (dry matter basis) respectively for 56 days. The specific growth rate, net production rate, protein efficiency ratio, proximate composition, and overall conditions of fish were not significantly varied between the fish reared completely with CFF and 25% substitution with A. pinnata. However, a significantly higher profit rate (431.49 USD ha −1 56 day −1 ) was calculated for fish reared in T 2 than other treatments. In contrast, there was a significant reduction of growth and other parameters of the fish that were observed in the case where more than 25% CFF was substituted with A. pinnata. The poorest performance was observed in fish fed completely with A. pinnata, at T 5 . Based on the results, 25% of CFF of Thai silver barb could be substituted with fresh A. pinnata without significantly lowering their growth and product quality and could contribute significant to a higher profit margin.

“…Fish are an almost unique source of the health beneficial n-3 LC-PUFA, EPA and DHA, for humans 49 , 50 . Previously, higher levels of EPA, DHA and n - 3 PUFA were recorded in Nile tilapia fed diets including Azolla filiculoides 51 and duckweeds are a good source of ALA, that is the precursor of n-3 LC-PUFA 16 , 17 , 52 . Therefore, in the present study, one focus was to determine if dietary duckweed can boost the levels of n-3 LC-PUFA in carp.…”

The potential nutritional value of duckweed Lemna minor (Lemnaceae) was evaluated for common carp Cyprinus carpio fry. Fish were fed diets containing five graded levels of duckweed: 0% (LM0, control), 5% (LM5), 10% (LM10), 15% (LM15) and 20% (LM20). The final weight and specific growth rate were significantly higher in LM15 and LM20 diets fed fish compared to others. Feed conversion ratio was minimum in fish fed diet LM20. Amylase activity was significantly higher in LM0 treatment. Total protease, trypsin and chymotrypsin activities showed linear relationships with the increased level of duckweed in the diet. Protein and essential amino acids contents were significantly higher in carp fed diets LM15 and LM20 compared to others. Lipid content was significantly higher in fish fed duckweed-based diets compared to control. A direct relationship was found between the inclusion level of duckweed in the diet and n-3 long-chain polyunsaturated fatty acid (LC-PUFA) content of carp. Contents of desaturated and elongated products of dietary linolenic acid (18:3n-3) including 20:4n-3, 20:5n-3, 22:5n-3 and 22:6n-3 increased in a graded manner with increasing dietary duckweed. The monounsaturated fatty acids and n-6 PUFA contents reduced significantly in fish fed duckweed. Expression of fads2d6, elovl2, elovl5 and fas were higher in carp fed diets LM10, LM15 and LM20 compared to control fish. The inclusion of L. minor in diet enhanced the nutritional value of carp by increasing protein, lipid, amino acids and n-3 PUFA contents.
