Age and growth of the yellowmouth barracuda Sphyraena viridensis (Cuvier, 1829) was examined in 698 individuals (184 < TL (mm) < 1210; 25 < TW (g) < 7125), sampled monthly from commercial catches in eastern coasts of Algeria between January 2007 and January 2008. Marginal increment analysis of 159 sectioned sagittal otoliths combined with information derived from length–frequency distribution showed that annulus formation occurs between June and August. Maximum observed age of males and females is 14 and 13 years respectively. Back calculations of total length-at-age were used to fit the data to the Bertalanffy growth model: TL = 1113(1 – e−0.165(t+2.251)) in males and TL = 958.3 (1 – e−0.247(t+1.422)) in females. The coefficient of allometry of the length weight relationship is 3.02 and 2.99 in males and females, respectively. Growth performance index Ø = 3.33. Natural mortality (M) was estimated as 0.45 year−1, fishing mortality (F) was 0.06 year−1and the exploitation rate (E) was 0.11.

阿尔及利亚东海岸黄口梭鱼 Sphyraena viridensis (Sphyraenidae) 的年龄、生长和死亡率

黄口梭鱼的年龄和生长绿藻(Cuvier, 1829) 对 698 个人 (184 <TL(毫米) < 1210; 25 <台湾(g) < 7125)，在 2007 年 1 月至 2008 年 1 月期间从阿尔及利亚东海岸的商业渔获物中每月取样。对 159 个切片矢状耳石的边际增量分析结合来自长度频率分布的信息表明，环空形成发生在 6 月至 8 月之间. 男性和女性的最大观察年龄分别为 14 岁和 13 岁。年龄总身长的反向计算用于将数据拟合到 Bertalanffy 增长模型：TL= 1113(1 - e−0.165(t+2.251)) 在男性和TL= 958.3 (1 – e−0.247(t+1.422)) 在女性中。男性和女性的长度重量关系的异速生长系数分别为 3.02 和 2.99。成长表现指数Ø = 3.33。自然死亡率 (M) 估计为 0.45 年-1, 捕捞死亡率 (F) 为 0.06 年-1开采率（E）为0.11。
