Threshold cycle values (Ct) of four housekeeping genes (<i>18s rRNA</i>, <i>GAPDH</i>, <i>β-actin</i>, and <i>EF1-α</i>) determined by qPCR from (A) testis samples of wild broodstock from different locations (Andaman sea and Gulf of Thailand) and domesticated shrimp with different growth stages (18-, 14-, 10-, and 4-month-old domesticated shrimp, DS), (B) ovary samples from wild broodstock with different ovarian maturation stages (Stages I–IV), (C) ovary samples of domesticated shrimp from different growth stages (18-, 14-, 10-, and 4-month-old domesticated shrimp, DS), and (D) ovary samples from 14-month-old domesticated broodstock before and after eyestalk ablation for 1, 4 and 7 days.
