本研究於2003年6月至2005年3月間，以水試一號試驗船於龜山島海域進行計7航次之IKMT拖網採樣，並使用ICLARM所發展的FiSAT軟體進行正櫻蝦年齡與成長研究。研究期間計測量正櫻蝦體長16820尾；其中雌、雄蝦分別為9,778及7,042尾，據以推估雌、雄與雌雄合併的VBGF之二成長參數即成長係數 (K) 與極限體長 (L_∞)，分示如下：(1) 雌蝦：K = 1.4 year^-1、L_∞ = 51.50 mm；(2) 雄蝦：K = 1.01 year^-1、L_∞ = 50.21 mm；(3) 雌、雄合併：K = 1.21 year^-1、L_∞ = 51.32 mm。分析台灣龜山島海域、東港海域與日本駿河灣所產正櫻蝦的成長表現指數 (ø') 顯示：ø' 以東港海域最高，次為龜山島海域，而以日本駿河灣為最低。依據三海域地理分布研判棲息水溫是影響正櫻蝦成長的重要因子。

Totally seven voyages of IKMT trawling of the R/V Fishery Researcher 1 were conducted on the waters off Guei-shan isle from June 2003 to March 2005. The FiSAT, which was developed by ICLARM and especially designed for estimating the growth of crustacean by analyzing the temporal series of length data, was used to estimate the growth of female, male and pooled sergestid shrimp. The sample sizes for female, male and pooled were 9778, 7042 and 16820, respectively. The estimated growth coefficient and infinite length of VBGF for female, male and pooled sergestid shrimp were denoted as following: 1) female: K=1.4 year^-1, L_∞=51.50 mm; 2) male: K=1.01 year^-1, L_∞=50.21 mm; 3) pooled: K=1.21 year^-1, L_∞=51.32 mm.
Compared with the growth performance indices (ø') of sergestid shrimp from Guei-shan isle, Tunkang, and Suruga Bay, Tunkang had the highest one and the followings were Guei-shan and Suruga Bay. Based on the geographical differences among those three localities, the study suggested that water temperature served as the key factor affecting the growth of sergestid shrimp.
