In decapod crustaceans, the conditions experienced during embryonic development trigger phenotypic plasticity of larvae at hatching. The objective this study was to test effects temperature Palaemon serratus on hatching larvae. We incubated egg-bearing females from eggs laying four temperatures (10, 15, 18 and 20°C). Weight, carbon nitrogen contents were measured newly laid freshly hatched dura...

The structure, ultrastructure and osmoregulatory function of the branchial chamber were investigated in Palaemon elegans (Rathke, 1837) by light microscope, electron microscope and immunohistochemistry methods, respectively. Each chamber possesses a branchiostegite, 3 epipodites and 8 phyllobranchiate gills. The lamellae are attached along the two outer surfaces of the triangular gill axis. Ult...

Multi-tiered oyster aquaculture cages may provide habitat for fish assemblages similar to natural structured seafloor. Methods were developed assess associated with gear and boulder using underwater video census combined environmental DNA (eDNA) metabarcoding. Action cameras mounted on 3 at a commercial eastern Crassostrea virginica farm (‘cage’) among boulders rock reef (‘boulder’) from June A...

Abstract The invasion of non-native species into an ecosystem can markedly alter the structure and functioning system. Yet, we have limited knowledge factors that determine success. Behavioural interactions been suggested as critical determinants success in animals, but exact mechanisms are less well known. We investigated if density-dependent behavioural could facilitated shrimp Palaemon elega...
