白虾：36-40规格和更大规格的拉丁美洲去头白虾报价就像列表显示的那样稳定.41-50和51-60两个规格的报价也非常稳定,虽然优质级别的已普遍有所减少.更小规格仍受到供应限制,报价也同样非常稳定.去头亚洲白虾报价仍然稳定,但是已感受到一些来自拉丁美洲白虾的压力了.替代品报价仍然与市场行情脱节.
草虾：由于限制供应,21-25规格和更小规格的去头草虾,报价仍非常稳定,特别是26-30和31-40这两个供应受限严重的规格.更大规格的价格比较稳定.这些规格优质级别产品值得关注.各地区的海外季节性替换供应都受到限制,且有加剧的趋势.
海湾国产虾：16-20和21-25两个规格国产虾的价格继续因为低供应而走势不稳.路易斯安那州沿海的捕虾季节已经开始,虾仁即将上市,在新季节产品上市前,库存仍会比较紧张,市场报价仍不稳定.
疑点：are full steady at listed levels although premiums have been less prevalent.
premiums的意思应该是优质级别的,因为报价里有premiums级别也有commodity级别的,但是这一句怎么翻译,都觉得不太满意.
二、Replacement pricing remains disconnected with current spot conditions.
这一句怎么翻译妥当一点呢?
三、 Premiums are noted on these sizes.
这一句是我最头疼的了,noted这里作何解?
