利用自制触球及迷宫法评估了百里香酚、香芹酚、丁香酚和肉桂醛4种香精对(4.45±0.58)g黄颡鱼(Pelteobargrus fulridraco)幼鱼的诱食剂量效应反应,试验结果表明:百里香酚、香芹酚和肉桂醛都对黄颡鱼有明显的诱食作用,其最适诱食浓度分别为(0.025~0.05)、0.025、0.007 g/m L;百里香酚诱食效果最佳(P0.05),但浓度过高,也会出现诱食抑制;而丁香酚对黄颡鱼幼鱼均无明显的诱食作用(P0.05)。随后在基础饲料中分别添加75、150、250、500和1000 mg/kg的百里香酚饲喂黄颡鱼幼鱼,8周的养殖结果表明黄颡鱼增重率(Y)与饲料中百里香酚添加量(X)之间可用二次方程式表示Y=-0.000 7 X2+0.796 3 X+107.08(R2=0.777 2),当黄颡鱼获得最大增重时,饲料中百里香酚的添加量为568.8 mg/kg。 相似文献

饵料对中间球海胆品质的影响 总被引：2，自引：0，他引：2
饵料种类对中间球海胆的品质有显著影响。长期摄食鲜海带或裙带菜的海胆生殖腺呈橘红色和橘黄色,摄食孔石莼为浅橘红色和橘黄色,摄食人工配合饲料为土黄色和乳白色。长期摄食鲜海藻类的海胆生殖腺味道甜美,口感上佳;而摄食人工配合饲料的则有苦涩味。饵料种类及其交替方式决定了海胆生殖腺色泽和口感的转变速度,其中鲜海藻类间转换速度基本一致,均需60d可完成;而人工配合饲料则需80d方能完成。中间球海胆消化道的颜色更易受饵料种类的影响,其转换速度与饵料种类和交替方式无关,20d即有明显表现,40d可完成。 相似文献

Essential oil incorporated alginate coating provides a novel way to improve the safety and shelf life of pangasius (Pangasianodon hypophthalmus) fillet. Oils from the leaves and buds of clove, flowering tops of rosemary, and dried seeds of thyme were incorporated separately in alginate coating. All the plant oils showed antibacterial activity, but the zone of inhibition was relatively larger for thyme oil. Alginate coating was performed using sodium alginate (1.5%), glycerol (10%), and calcium chloride (2%) and plant oil at 1% (v/v). The coated fillets were stored under chilled conditions and samples were analyzed for bacteriological, chemical, sensory, color, and texture parameters. Psychrotrophic counts crossed 7 log cfu/g by the 13th day and 15th day of chilled storage in control and plant oil treated fillets, respectively. The peroxide value of treated fillets was relatively low. Texture profile analysis indicated that plant oil incorporated alginate coating reduced the rate of loss of texture (softening) during chilled storage. Plant essential oil incorporated alginate gels were relatively better compared to control fillets in preserving pangasius fillet quality during chilled storage, and incorporation of thyme oil was relatively better compared to clove leaf oil, clove bud oil, and rosemary oils. 相似文献

The study was to investigate the effects of garlic (Allium sativum) powder on feeding attraction activity, growth performance and digestive enzymes of juvenile Japanese seabass, Lateolabrax japonicus (initial weight: 29.82 ± 0.24 g). Six concentration gradients (0, 5, 10, 15, 20 and 25 g/kg diets) were formulated for luring and feeding experiment. The results showed a clear attractive trend of garlic powder for L. japonicus. A 28‐day feeding experiment indicated garlic could reduce the feed conversion ratio (FCR) (p < .05). The content of the body crude lipid was significantly increased at 10–15 g/kg diet (p < .05). Digestive enzyme activities including trypsin, amylase (AMS) and lipase (LPS) in the intestine were the highest at 10 g/kg diet (p < .05). Overall, garlic powder provides a promising and effective method for Japanese seabass healthy culture by improving fish growth and digestive ability. The results of this research suggested the additive suitable dosage of garlic powder was about 10 g/kg diet. 相似文献

Garlic (Allium sativum) has been shown to possess antimicrobial properties against a range of disease‐causing agents, including fish parasites. Our study aimed to investigate the potential use of garlic as a treatment against Cryptocaryon irritans infection, using guppies (Poecilia reticulata) as the fish model. Garlic was freeze‐dried, powdered, and used as it is or as an aqueous extract. The content of allicin, its main active ingredient, was 1.25 mg/g in garlic powder and 0.82 mg/ml in the aqueous extract, as determined by HPLC analysis. Aqueous garlic extract fully immobilized C. irritans theronts and protomonts within 20 and 40 min, respectively, following exposure to 5 µl/ml. Treatment trials were performed, in which infected fish were fed with garlic powder‐supplemented feeds (5%, 10%, or 20% supplementation), bathed in garlic aqueous extract (250 or 500 µl/L) and subjected to a combined treatment which included both feeding and bathing. Results revealed that the tested treatments failed to cure the infection, though reduction in infection intensity on the caudal fin, but not on the gills, was evident following dietary supplementation with 20% of powdered garlic in one of the trials. 相似文献

Juvenile and adult black sea bass (Centropristis striata L.) were exposed to various concentrations of four anaesthetics to determine practical dosages for handling as well as for procedures such as bleeding, ovarian biopsy or tag implantation. In experiment 1, juveniles exposed to either 2.0 mg L?1 metomidate, 15 mg L?1 clove oil, 70 mg L?1 tricaine methanesulphonate (TMS) or 200 mg L?1 2‐phenoxyethanol (2‐PE) reached stage II of anaesthesia in 3–5 min and could be handled for weighing and measuring. All fish had completed recovery to stage III within 6 min. In experiment 2, the established concentrations of each anaesthetic were tested on juveniles to determine their ability to prevent a reflex to a subcutaneous needle puncture. All of the fish exposed to clove oil (20 mg L?1) and 40% of the TMS‐treated (70 mg L?1) fish reacted while none of the fish anaesthetized in metomidate (2.0 mg L?1) or 2‐PE (200 mg L?1) responded to the needle puncture. In experiment 3, metomidate (5.0 mg L?1), clove oil (30 mg L?1) TMS (125 mg L?1) or 2‐PE (300 mg L?1) were all effective for performing an ovarian biopsy or tag implantation on adults. In experiment 4, TMS (125 mg L?1) exacerbated the cortisol response to a short handling stressor during a 30 min exposure. Fish anaesthetized in 2‐PE (300 mg L?1), metomidate (5.0 mg L?1) or clove oil (40 mg L?1) had increased cortisol levels associated with the handling stressor but there were no further increases during the remainder of the experimental period. The results demonstrate that these anaesthetics are effective for sedation and anaesthesia of black sea bass and that the best choice is dependant upon the procedures to be performed. 相似文献
