Fig 5. The gastrointestinal tract of Asian seabass is influenced by the different feeds.
External circumference of serosa (Panel A), mucosal height (Panel B), muscularis layer thickness (Panel C) and goblet cell number (Panel D) were measured from sections of the mid gut of 168 dph-old Asian seabass fed frozen baitfish (Group A) or pelleted commercial feeds (Groups B-D) for 61 days. Values are represented as percentages over control (A) value. Post ANOVA Dunnett’s multiple comparisons test was performed between the mean of each group with the mean of the control group. Means significantly different from Group A are noted with *—Padj < 0.05; **—Padj < 0.01; ***—Padj < 0.001; or ****—Padj < 0.0001. Representative examples of the mid-gut histological sections are shown on the right (Panels E&G–Group A; F&H–Group C). Panel E: Blue line = External circumference of serosa (S); Panel G: red = high of Mucosa (mu), purple = Thickness of muscularis layer (m), green = Goblet cells (gc); Panels E&F - 5x magnification; Panels G&H - 10x magnification. Panels E&H; scale bar = 100μm.
