We recorded the initial appearance of pigmentation on blind side in olive flounder, Paralichthys olivaceus , and investigated morphological features abnormal blind‐side hypermelanic juveniles at microscopic level. In addition, we examined development malpigmentation flounder during early development, from 24 to 94 days after hatching (d.a.h.). A total 60 were collected every 7 d assessed for quantitative pattern changes pigmentation. The primitive spot first patch visible under a microscope...
To determine whether rearing density affects the hypermelanosis on blind side (ambicoloration) of olive flounders Paralichthys olivaceus, we reared fry with an unpigmented non-eyed (blind) in duplicate at densities 150 individuals/<TEX>$m^2$</TEX> (commercial production density: control) and 450 (high group) for 90 days 1-t dark-green fiberglass reinforced plastics (FRP) tank. We recorded feed intake, conversion efficiency (FE), growth survival, measured ratios staining blind-side area...
In Pleuronectiformes, blind-side malpigmentation (hypermelanosis) is common in cultured flatfishes, and economically important. To understand the mechanism of hypermelanosis we examined when initially occurred, studied how symptoms proceeded during early development starry flounder, Platichthys stellatus. assess quantitative pattern changes skin, observed morphological whole body from 22 (total length [TL] 10.0±0.2 mm weight [BW] 8.8±0.57 mg) to 110 days (TL 23.4±0.7 mm, BW 193.6±23.3 after...
Physiological responses of mullet Mugil haematocheilus to cold shock in winter were investigated. The experimental mullets initially acclimated at <TEX>$10.0^{\circ}C$</TEX> and then the water temperature was reduced <TEX>$-1.2^{\circ}C$</TEX> for experiment. stress monitored nearly 50 hours. parameters include survival rate, plasma alanine aminotransferase (ALT), aspartate (AST), glucose (GLU), total protein (TP), electrolytes <TEX>$(Na^+,\;K^+,\;Cl^-)$</TEX>, cortisol thyroid hormones...
Abstract The development of thyroid follicles and the change hormone concentrations in whole body were examined, relationship between follicle differentiation growth also studied during early Korean rockfish Sebastes schlegeli . Total length (TL) weight (BW) larva at parturition 6.3 ± 0.1 mm 3.6 mg respectively. larvae transformed to juveniles from 20 30 d after with continuous growth. primordium was observed histologically newly born larvae, suggesting that may have been formed yolk‐sac...
To evaluate the influence of burrowing substrate on rearing performance and ambicoloration cultured flounder, Paralichthys olivaceus, we compared daily food intake (DFI), feed efficiency (FE), survival, growth, proportion pigmented skin blind side, ambicolored fish. We reared juvenile flounders [total length (TL) <TEX>$4.46{\pm}0.06cm$</TEX>, body weight (BW) <TEX>$0.77{\pm}0.03g$</TEX>] in dark-green fiberglass-reinforced plastic (FRP) aquariums without (control) or with gravel at a density...
To examine the influences of water temperature and stocking density on feeding, growth blind-side hypermelanosis starry flounder Platichthys stellatus, we performed an experiment with fry at two densities: 2 8 fish/L. The had a total length <TEX>$3.2{\pm}0.1cm$</TEX>, body weight <TEX>$0.6{\pm}0.1g$</TEX>, pigmented patches (pigmented ratio <TEX>$2.6{\pm}0.4%$</TEX>) blind side. Duplicate experiments were conducted in 93.7 L glass tanks for 120 days, from July to November. We determined...
