Background: Lobsters are highly expensive and demanded sea food due to their taste and nutritional value. Especially people around the world prefer more and pay huge for live lobsters. They are being exportedin different forms like frozen, whole cooked, whole chilled frozen tails and as lobster meat. As there is an extreme targeted catch these lobster resources are being exploited. The spiny lobsters, P. homarus and P. ornatus are one among the major distributed lobster species along the Gulf of Mannar, South east coast of India. The two lobster species are flavored seafood in many countries because of their more nutrient content are fine flavor. Methods: The experiment was conducted for a period of one year (2018-2019). The spiny lobsters P. homarus and P. ornatus werecultured under captivity in FRP tanks for a period of one year. After the study period the animal muscle was taken lyophilized and stored at 20o C and used for further analysis. Result: This experiment was conducted to evaluate the crude protein, carbohydrates, crude lipids, moisture ash, amino acids and fatty acids from harvested spiny lobster, P. homarus and P. ornatus. The maximum protein content carbohydrate, lipid, Moisture, Ash and amino acids, fatty acids was noted in P. ornatus. The biochemical compositions amino acids and fatty acids were observed moderate and lowest in P. homarus.

Abstract BackgroundThe semiterrestrial isopod, Ligia exotica represents one of the oldest documented species introductions of marine organisms and is known as an intermediate form between marine and strictly terrestrial isopods. They are considered to make a significant contribution to nutrient cycling and ecosystem services in the near shore environment and in helping to maintain the biodiversity of the coastal zone. The special biological role and its environmental plasticity contribute to its potential value for academic research. In order to explore the practical value for food & feed of Ligia, this study focused on growth rate under laboratory rearing conditions and detailed analysis of the overall nutrient content of the species in comparison to two other aquatic food media (krill and fish meal). ResultsEvaluation of the growth rate of juveniles demonstrated a weight gain rate of 13,026.76% to70 days after hatching (DAH) and a total specific growth rate of 6.97%, which suggests it is a relatively fast-growing species of the Ligiidae family. Compared with Antarctic krill meal and commercial white fishmeal, Ligia meal is closer to krill in amino acid content and contained 43.45% (wet weight) crude protein. Its essential amino acids content was the lowest (35.21% in total amino acids) but the proportion of flavor amino acids was 49.37%, higher than that of krill meal (38.98%) and fish meal (39.80%). In particular, the content of taurine (9.45 g/100 g) was much higher than that of the other two meals. Amino acid score (AAS) and Chemical score (CS) show that the most restricted amino acids of isopod meal are methionine and cysteine, which are less than half of those of krill meal and fish meal. The extremely unbalanced amino acid composition may affect the absorption and utilization by consumers. In terms of fatty acids, isopod meal contains 8.99% (wet weight) crude fat and more saturated fatty acids (33.66%). The total polyunsaturated fatty acids (PUFA) are only 23.61%, lower than 40.50% of krill meal and 47.27% of fish meal. The Σ n-3 PUFA content is even lower with only 12.12%. A total of 12 vitamins were examined. The VK1, VE, VB2, VB3, VB5 content of isopod meal were significantly higher than those of krill meal and fish meal. Similarly, most of the 11 mineral elements are the highest in isopod meal including the ubiquitous elements of calcium and potassium, and the trace elements ferrum, chromium, and selenium. ConclusionsLigia offers potential as an alternative natural food source especially in aquaculture given the growth rate under culture and the overall nutrient content (as demonstrated by the preliminary trials on cuttlefish) but Ligia collected in most of the field would be deemed unfit for human consumption because of the relatively low nutritional value and heavy metal content exceeding the provided standard. At the same time, Ligia isopods offer some potential to become a crustacean model animal for commercial aquaculture crustaceans for research on physiological and other aspects because of their position in ecological food chain and unique semi-terrestrial characteristics that allow them to be cultured out of seawater. Further study is warranted to elucidate its biological characteristics.

In order to explore the potential value of Ligia as an animal food source, this study focused on the growth rate under laboratory rearing conditions and conducted a detailed analysis of the overall nutrient content of the species in comparison to two other marine food media (krill and fish meal). Evaluation of the growth rate of juveniles suggests it is a relatively fast-growing species of the Ligiidae family. The essential amino acids content Ligia meal is the lowest amongst the three studied media but the proportion of flavor amino acids, and in particular taurine, was higher. The most restricted amino acids of isopod meal are methionine and cysteine. The significantly unbalanced amino acid composition of Ligia meal may affect the absorption and utilization by consumers. In terms of fatty acids, the total polyunsaturated fatty acids in the isopod is very low. A total of 12 vitamins were examined. The VK1, VE, VB2, VB3, VB5 content of isopod meal were significantly higher than those of krill meal and fish meal. Similarly, most of the 11 mineral elements are highest in the isopod meal. Ligia therefore offers potential as an alternative natural food source in animal given the growth rate under culture and the overall nutrient content. But Ligia collected in most of the field would be deemed unfit for human consumption because of the relatively low nutritional value and heavy metal content exceeding the provided standard. Further study is warranted to elucidate the biological characteristics of isopods and how its diet is reflected in its nutritional value to consumers.

The nutritional compositions, including amino acids and fatty acids profile in muscle were compared between wild and farmed Carassius auratus to evaluate the nutritional value. The contents of moisture, crude protein, fat, carbohydrate and ash in wild C. auratus were 74.47%, 19.12%, 3.72%, 1.52% and 1.18%, and those of farmed C. auratus were 74.03%, 18.41%, 4.54%, 1.95% and 1.06%, respectively. The contents of total amino acids (TAA) and essential amino acids (EAA) in wild C. auratus were obviously higher than those of farmed group (dry sample), whereas the protein of farmed C. auratus has more well-balanced amino acid composition based on the Amino acid scores. Abundant polyunsaturated fatty acids (PUFAs) were observed in the muscles of two groups, however the ratio of n-6/n-3 especially the wild group were significantly higher than the value (4.0 at maximum) recommended by UK Department of Health and the value of China (4:1~6:1). So the fatty acids composition of C. auratus was not ideal for the human health.

The objective of this work was to determine the nutritional value of different protein sources for "dourado" (Salminus brasiliensis). Thirty juveniles per group (33.51±1.4 g) were hand fed on a reference diet (70%) added of tested ingredients (30%) and chromium oxide III (0.1%). Apparent digestibility coefficients of the gross energy (ADC GE), crude protein (ADC CP) and amino acids of the tested ingredients were evaluated. Corn gluten meal yielded the best results for ADC GE and ADC CP (95.7 and 96.9%, respectively) amongst plant ingredients. Spray-dried blood meal yielded the best values of ADC GE and ADC CP amongst animal ingredients (94.1 and 96.3%, respectively). Wheat bran yielded poorest ADCs coefficients (77 for ADC GE and 88.2% for ADC CP).

The study aimed to evaluate the addition of banana blossom (12.5, 25, 37.5, and 50% w/w) on nutritional quality, histamine content, bacterial count, and sensory characteristic in the fish floss prepared from little tuna (Euthynnus affinis). The crude protein content, essential amino acids, lipid, and polyunsaturated fatty acids (PUFA) steadily decreased (p <0.05), while the crude fibre, carbohydrate, and ash components of the tuna floss, increased significantly (p <0.05) with increasing levels of banana blossom. The contents of protein, fat, ash, fibre, carbohydrate, and moisture ranged 28.13 – 30.27%, 14.79 – 18.02%, 4.45 – 5.68%, 2.6 – 3.5%, 27.81 – 31.01, and 16.45 – 17.39%, respectively, and most of them met the Indonesian National Standard. For essential and non-essential amino acids, the level varied about 102.82 mg.g-1 to 206.76 mg.g-1 and 79.71 mg.g-1 to 138.76 mg.g-1, respectively in the treated tuna flosses. Moreover, ranging 13.72 – 16.29% of PUFA was found in all treated flosses. The most significant effect was found in the histamine levels of the tuna flosses, especially in the 50% added floss sample. Moreover, bacterial counts and heavy metals content were lower than the maximum limits regulated by the Indonesian National Standard. For sensory evaluation, the banana blossom-added samples significantly increased (p >0.05) the acceptability score for all attributes assessed. Taken together, the tuna floss added with 37.5% of banana blossom may be potentially developed as a low-histamine tuna-based product with high ffibre andEPA+DHA, as well as highly acceptable for consumers.

Abstract The objective was to test the hypothesis that there is no effect of origin or processing procedure on the standardized ileal digestibility (SID) of amino acids (AA) and crude protein (CP) in sunflower co-products. Six sources of sunflower meal (SFM) and 1 source of sunflower expellers (SFE) were obtained from Ukraine, Italy, Hungary, and the U.S. Each source of SFM or SFE was the only source of CP and AA in 1 diet and an N-free diet was also used for a total of 8 diets. Eight barrows (body weight: 28.5 ± 2.4 kg) had a T-cannula installed in the distal ileum and were allotted to 1 of the 8 diets using an 8 × 8 Latin square design with 8 periods. The Lys:CP ratio in the 6 sources of SFM ranged from 3.10 to 3.96% with CP concentrations ranging from 27.34 to 36.75%. Crude protein in SFE was 26.87% and the Lys:CP ratio was 3.51%. Concentrations of acid hydrolyzed ether extract in the 6 sources of SFM ranged from 0.60 to 3.11%, but SFE contained 8.77%. Results indicated that the SID of CP was lower (P &lt; 0.05) in SFM from Hungary compared with all other sources of SFM except for 1 of the sources from Ukraine. There were no differences in the SID of Lys, Met, and Trp among sources of SFM, but for most of the remaining indispensable AA, the SFM from Hungary had less (P &lt; 0.05) SID than the other sources. However, only few differences in SID of indispensable AA were observed among the other sources of SFM, but the SID of CP and all AA except Trp was greater (P &lt; 0.05) in SFE compared with SFM. In conclusion, there were only few differences in the SID of the first limiting AA among SFM obtained from Ukraine, Hungary, Italy, and the U.S., but the SID of CP and AA was greater in SFE than in SFM indicating that processing of sunflower seeds influence the nutritional value.
