The sodium chloride content of the sample Pneumatophorus japonicus sauce was greater than 25%. The total soluble nitrogen content was greater than 2.1 g/100mL, and the amino nitrogen content was greater than 1.2 g/100mL. The mineral content was abundant in the Pneumatophorus japonicus sauce, the calcium content and the magnesium content were 391.50±0.03 and 375.00±0.02 mg/L respectively, much higher than those in other samples. The iron content and the zinc content were 22.30±0.04 and 2.80±0.03 mg/L, respectively. The content of free amino acids was 5 552.17 mg/100mL, the content of essential amino acids was 2 666.00 mg/100mL,The taurine content was 113.05 mg/100mL. The antioxidant activity of the fermentation broth was 90.48%, while the TCA soluble peptide content was 29.04 mg/mL. Pneumatophorus japonicus sauce is nutritionally rich and has special physiological activity.展开更多

This paper reviews some Thai research papers for referable benefit of international countries. The relationships of fecundity with body length and weight of wild population are related （F = 0.54L3339, F = 435.41W^S399）. Length-weight relationships of both sexes are W = 0.0059L3044s. Sex ratio is 1：1 and spawning season starts during March to June, the egg is adhesive demersal. Average mature size of both sexes are from 40-60 cm TL and 1,100-2,900 g. Effect of 3 types of hormone on induced ovulation, including HCG, pituitary gland, and buserelin in combination with domperidone are not signiticantly different （P 〉 0.05）. Hatching occurs in 24-25 hours after fertilization. The hatching percentage is 80%. Nursing and feeding strategies are also reviewed in this paper.展开更多

Currently in the dam ＂El lnfiernillo＂ in Michoacan Mexico, has a large population of devil fish （Pterygoplichthys spp.）, which is an economic and ecological problem, because it is not consumed by humans and causes pollution to be discarded directly into the environment. For that reason the objective of this study was to evaluate the use of silage acid devil fish （SADF） in fattening beef cattle as a protein supplement. SADF is defined as a product semi-liquid or pasty mixed with formic acid, which leads to a decrease in pH to near 4.0. Used 18 young bulls （Bos taurus × Bos indicus） for 60 days with a starting weight of 278.9 ± 51.2 kg, housed in individual pens with food and water ad libitum were randomly assigned to three treatments with different levels of inclusion SADF （0%, 12% and 18%）. They were weighed to the beginning of the experiment and later every 30 days, previous fasting of 24 hours. To determine the food consumption, weigh every day the offered food and the surplus. There were no significant differences （P 〈 0.05） among treatments with different levels of inclusion of SADF with respect to daily weight gain, with values of 952 ± 324, 927 ±322 and 854 ± 307 g/day, respectively. The dry matter intake （DMI） was 8.9, 9.3 and 7.7 kg/day to 0%, 12% and 18% of SADF, respectively. In the same values for feed conversion were 9.34, 10.03 and 9.01 kg DMI/kg of weigh live, and carcass yield of 60.6%, 60.3% and 58.5%, respectively. It is concluded that fish silage acid devil is an excellent alternative in feeding beef cattle as a protein supplement.展开更多
