As to whole growth period, the spring crop grows for 90-110 d, the autumn crop grows for 70-80 d, and the fruit development period is 27-29 d. The fruit is oblong with a fruit shape index of 1.5, the average single fruit weight is 3.18 kg, and the fruit surface is smooth in deep green color with dark green netted stripes. The fruit flesh is bright red, crisp, with a soluble solid content in the center of 11.5%. The fruit has a peel thickness of 1.0 cm with high storage tolerance, good appearance and good commodity. The variety is suitable for Guangxi, Guangdong and Halnan.展开更多

Estimated ages ranged from 144 to 633 days, confirming that the squid is a short-lived species with longevity no longer than 2 years. Occurrence of mature females and hatching in each month indicated that Humboldt squid spawned year-round. Back-calculated hatching dates for the samples were from January 22^nd, 2008 to April 22nd, 2010 with a peak between January and March. Two size-based and two hatching date-based populations could be defined from mantle length （ML） at maturity and back-calculated hatching dates, respectively. Females matured at a larger size than males, and there was a significant difference in ML at maturity between the two hatching groups （P〈0.05）. The waters adjacent to 1 l^S off the Peruvian EEZ may be a potential spawning ground. This study shows the complexity of the population structure and large variability in key life history parameters in the Humboldt squid off the Peruvian EEZ, which should be considered in the assessment and management of this important resource.展开更多

Qing Xin An Shen Fang ([symbol: see text] a formula for clearing away the heart-heat to induce tranquilization) was used in the treatment group and compared with mexiletine and Fu Fang Dan Shen Tablets ([symbol: see text] Compound Salvia Tablets) used in the control group. The results turned to be that the markedly effective rate was 85.1% and the total effective rate 96.3% in the treated group, better than that in the control group, with the former having a good antihypertensive and antihyperlipemic effect and an effect of improving microcirculation and clinical symptoms.展开更多

Besides its toxicity due to the accumulation of tetrodotoxin in its body, it is causing damage to fishing gears and fishermen＇s catches. This study aims to provide data on the population structure and sexual maturity of this species in the eastern basin of the Mediterranean. A total of 214 individuals were collected in the coastal marine waters of Lebanon and Syria, between January 2012 and June 2013 by means of different types of nets and lines, on soft bottoms, at depths ranging from 10 m to 170 m. The TL （total length） of the samples varies between 10.8 cm and 71 cm. The most common size classes, represented by 125 individuals, are the ones between 30 cm and 50 cm TL, with a bulge at 40 cm, represented by 44 individuals. The average TL is 43.99 cm （standard deviation： SD = 17.65） for both males and females. The TW （total weight） of the specimens ranges between 14 g and 4,603 g with an average value of 1,458.52 g （SD = 1,329.49）. The sex ratio （M/F） is 1：1.35 with a total number of 87 males, 118 females and nine unidentified individuals. The weight-length relationship （TW = aTLb） shows a negative allometric growth with b = 2.9481 and R2 = 0.9806. The condition factor （K） is close to one for all samples. The average value of the GSI （gonadosomatic index） shows a substantial increase from winter to spring. The spawning takes place between April and June.展开更多
