摘    要:为探究不同养殖模式下斑点叉尾鮰的生长性能和肌肉品质特性,随机选取传统池塘(TP)、高密度循环水系统(HD-RAS)和水泥池塘(CP)养殖模式下的鲜活斑点叉尾鮰,测定其生长状况,以及肌肉营养成分、颜色、持水力和质构特性。结果显示,TP和HD-RAS的斑点叉尾鮰的增重率和特定生长率差异不显著,但均高于CP;CP的肝体比(2.35%±0.22%)显著高于TP和HD-RAS;与TP相比,HD-RAS和CP肌肉的粗脂肪含量更低,粗蛋白和灰分含量更高;HD-RAS肌肉的亮度值(L*)(58.18±3.56)、红度值(a*)(6.05±1.08)最高,CP最低,分别为48.15±6.04和4.81±0.84;传统池塘养殖的斑点叉尾鮰熟肉率最低,离心损失、滴水损失和失水率最高,HD-RAS和CP之间差异不显著;HD-RAS和CP肌肉的硬度、咀嚼性和弹性显著高于TP,但3处理组间的内聚性和回复性没有显著差异。研究表明,与传统池塘养殖模式相比,水泥池塘养殖模式易造成斑点叉尾鮰生长减慢,而高密度循环水养殖模式对斑点叉尾鮰生长性能没有显著影响,并且在该养殖模式下肌肉具有更高的持水力、质构特性,同时呈现高蛋白、低脂肪的营养特点。

关 键 词:斑点叉尾鮰  高密度循环水养殖  生长性能  营养成分  肌肉品质

Abstract:In order to investigate the growth performance and meat quality characteristics of I. punctatus cultured under traditional pond (TP), high density recirculating aquaculture system (HD-RAS) and cement pond (CP), the growth performance, nutritional composition, colour, water-holding capacity and texture of muscle from I. punctatus selected randomly were evaluated. The results showed that the weight gain rate and specific-growth rate between TP and HD-RAS groups had no significant difference, but higher than those of CP group which had the highest ratio of liver-somatic index (2.35%±0.22%). In comparison with TP group, the samples from HD-RAS and CP groups exhibited lower content of crude fat but higher content of crude protein and ash. The highest values of lightness (L*) (58.18±3.56) and redness (a*) (6.05±1.08) of HD-RAS group were obtained, and the lowest (48.15±6.04 and 4.81±0.84, respectively) were CP group. TP group exhibited lowest cooked rate, highest centrifugal loss, drip loss and liquid loss. Meanwhile, the difference between HD-RAS and CP groups was not statistically significant. The hardness, chewiness and springiness of HD-RAS and CP groups enhanced significantly compared with those of TP group. Additionally, no significant difference in cohesiveness and resilience was observed among the three groups. Given the results, the cement pond aquaculture mode resulted in a slower growth of I. punctatus. Compared to traditional aquaculture mode, the high density recirculating aquaculture system had no negative effect on the growth performance. Besides, the I. punctatus muscle from high density recirculating aquaculture pond exhibiting higher water-holding ability and better textural properties had characteristics of higher content of protein and lower content of fat.
Keywords:Ictalurus punctatus  high density recirculating aquaculture  growth performance  nutritional composition  muscle quality
