Influence of Moult Cycles on Digestive Enzyme Activities during Early Larval Stages of Panulirus ornatus

Figure 1

Observed and fitted values (±95% confidence intervals) for the generalised additive models illustrating fluctuations in total (mU larva⁻¹) activities of (a) α-amylase, (b) non-specific esterase, and (c) trypsin-like protease in early larval stages (stages I–III) of Panulirus ornatus during moult cycles. (d) Fluctuations in (a)–(c) visualised in relative terms with unity-based normalised data. Dashed vertical lines denote when sampled larvae had completed ecdysis.
