Right now, high economical value shrimp species is vaname shrimp (Litopenaeus vannamei). Salinity gives impact to shrimp live, immunity and health. Stress from salinity shock will reduce shrimp health and production because of pathogen attack. White faeces syndrome (WFS) is a shrimp disease which frequently occured in an intensive farm. Fighting against WFS has been done with several methods, among other things by using ink extract as metabolite product of squid (Loligo sp.) because of its antibacterial content. To solve the problem, combination of ink extract with salinity treatments to CypA gene expression THC, DHC and digestibility of vaname shrimp (L. vannamei) was investigated. The best treatment using squid ink extract was 27 ppt salinity for vaname shrimp (L. vannamei) against WFS, because it gave the highest SR (85.73%), increased protease until 378 × 10⁻³ U/ml, amylase until 4.029 × 10⁻³ unit/ml and lipase until 3.613 × 10⁻³ unit/ml. and also non‐specific immune, i.e. THC 11.89 × 10⁶ cells/ml and DHC (hyaline was 39.09%, granular cell was 21.43% and semi‐granular cell was 47.74%), while mutation (>1%) was happened in CypA gene.

鱿鱼（Loligo sp。）墨水提取物对白虾粪便综合征（WFS）的南美白对虾（Linameenaeus vannamei）的血细胞，消化酶和CypA基因表达的治疗作用

目前，高经济价值的虾类是香草虾（Litopenaeus vannamei）。盐度会影响虾的存活，免疫力和健康。由于病原体的侵袭，盐度冲击产生的压力会降低虾的健康和产量。白色粪便综合征（WFS）是一种虾病，在集约化养殖场中经常发生。对抗WFS的方法有很多种，其中包括由于其抗菌成分而使用墨水提取物作为鱿鱼（Loligo sp。）的代谢产物。为了解决这个问题，将墨水提取物与盐度处理相结合，以处理CypA基因表达THC，DHC和虾的消化率。）进行了调查。使用鱿鱼墨汁提取物的最佳处理方法是对WFS的南美白对虾（L. vannamei）的盐度为27 ppt ，因为它具有最高的SR（85.73％），蛋白酶增加至378×10 ^-3  U / ml，淀粉酶直至4.029×10 ^-3单位/毫升和脂肪酶直到3.613×10 ^-3 单位/毫升。以及非特异性免疫，即THC 11.89×10 ⁶细胞/ ml和DHC（透明质酸为39.09％，颗粒细胞为21.43％，半颗粒细胞为47.74％），而CypA发生了突变（> 1％）基因。
