Özet

Analysis of empirical laboratory data of larval growth rate variation of five cohorts of larval and early juvenile spotted sea trout from hatching to 30-37 day emphasizes the differentiation during early-life history stages. Batch growth-rate variability increased steadily with developmental stage from hatching process by flection in terms of standard length and dry weight variations. Results revealed age- and developmental stage. Specific growth rates show a curvilinear relationship with an intermediate maximum end of the flection stage extending into the post-flection stage. Growth rates of older flection and post-flection larvae are more determinative about overall average of larval batch growth rates but less determinative about younger pre-flection or early flection larval growth rates.
