Description:
The aim of this study was to determine the qualitative characteristics of ready-made fish paste made from minced meat (Clupeonella cultriventris) The effect of different levels of herbal supplement of Cumin powder (Cuminum cyminum) on growth, survival and carcass composition of the Litopenaeus vannamei was evaluated in the summer of 1395 for 56 days at the Persian Gulf Aquaculture reproduction and reconstruction center. For this purpose, four groups of shrimp with an average weight of 3.45±0.3 g in 300 liter fiberglass tanks with a density of 60 shrimp per tank, with different levels (0.5, 1 and 1.5 percent) was supplemented. The Cumin powder was fed with 3 replicates. At the end of the period, growth indices (average body weight gain, body weight gain, specific growth ratio and feed conversion ratio), survival rate, and chemical composition of these treatments were compared with control treatment. The results showed that the treatment with 1% Cumin powder had higher growth indices and better survival than other treatments (p〈0.05). In the case of carcass biochemical analysis, the results showed a significant increase in protein and fat content and a significant decrease in moisture content in Cumin powder treatments compared to control (p 〈0.05). The results of this study showed that 1% Cumin powder in diet could be used to improve the growth performance, survival and quality of the carcass composition of white shrimp (Litopenaeus vannamei).and silver carp (Hypophthalmichthys molitrix) and its shelf-life at a refrigerated temperature.This compilation was performed in five treatments including amounts 100, 75, 50 and 25 percent of processed fish meat were cured. The treatments were packed in heat-resistant glass after pasteurization. Samples were stored at 4oC for 40 days.The amount of TVB-N in the experimental treatments during the course of the change was increased that this factor varied between15.25-31.25 mg/100 g of meat in experimental treatments. This factor was in the 100% rolled silver carp treatment until the end of the shelf life in the standard range. The amount of tybarbibacteric acid increased during storage period varied between 0.13- 2.11mg malondialdehyde/1000g in experimental treatments, but this factor was in the 100% treatment of silver carp paste after the end of the maintenance period in the standard range (less than 1.8 mg/100gr), in other treatments, after 30 days, was more than standard limitation. The pH changes in treatments did not significantly decrease (P〉0.05), this factor varied between 5.05 to 5.93 in the experimental period. Total bacterial counts, psychrophilic bacteria and coliform and molds were not observed in experimental treatments during storage period. Microbial contamination was not observed during the storage period in the refrigerator in the experimental treatments. The taste and texture in silver carp treatment (100%) were better than other treatments. The ash, protein and fat in 5 treatments did not significantly change during storage (p〉0.05). The moisture content was not significantly increased in all five treatments during storage (p〉0.05). Results showed treatment of processed carp (100%) was better than other treatments (p〈0.05).
