Abstract Water management becomes increasingly important issue worldwide. Its usage and sustainability are widely discussed in fish breeding industry. The content of ammonium ions (NH4+) produced by fish metabolism is unfavourable for the fish stock and requires frequent water change. However, water pollution can be reduced by using zeolite materials capable of removing ammonium cations more efficiently than nitrifying bacteria used in biological filters (bacterial carriers). Three zeolite mater...

Abstract The aim of this study was to evaluate the feasibility of producing the Amazon river prawn (Macrobrachium amazonicum) with tambaqui (Colossoma macropomum) in integrated multi-trophic aquaculture (IMTA) systems. An experiment was carried out in a completely randomized design with four treatments (types of production systems) and three replicates per treatment (ponds): prawn monoculture (30 prawns. m−2); fish monoculture (3 fish. m−2); IMTA with prawns and fish free-swimming in the same po...

Abstract Odd-skipped related 1 (OSR1) from Pinctada fucata martensii (PmOSR1) was cloned in this study. PmOSR1 contained an open reading frame measuring 951 bp that encoded a polypeptide of 316 residues. Domain analysis also revealed that PmOSR1 had a typical ZnF_C2H2 domain, indicating high identity with OSR1 protein sequence from Crassostrea gigas (55.25%) and Mizuhopecten yessoensis (65.48%). The expression pattern analysis of PmOSR1 revealed its wide expression in the tissues and development...

Abstract Intestinal microbiota plays important roles in animal development, but little is known about intestinal microbial community changes of amphibian during metamorphosis. In our research, we investigated the intestinal bacteria community in 120 tadpoles of Rana chensinensis (R. chensinensis) at five key developmental time points via 16S rRNA amplicon sequencing. We counted morphological parameters of the body and intestine of R. chensinensis tadpoles at varying developmental stages. Our sur...

Abstract Fighting and cannibalism between crabs are key factors that restrict increases in production and economic benefits. Temperature is an important environmental factor that affects the agonistic behavior and physiological activities of crustaceans. To explore the response mechanism of energy metabolism associated with agonistic behavior, we quantified the agonistic behavior and the concentrations of glycogen and key metabolites of the swimming crab (Portunus trituberculatus) at different t...

Abstract This study was conducted to investigate the effects of dietary fish oil replacement by soybean oil and l -carnitine supplementation on growth performance, fatty acid composition, plasma biochemical parameters, lipid metabolism, hepatic antioxidant ability and morphology of juvenile largemouth bass, Micropterus salmoides. Five isonitrogenous and isoenergetic experimental diets were formulated by replacing 0 (Diet 1), 50% (Diet 2) and 100% (Diet 3) of fish oil by soybean oil, and 50% (Die...

Abstract Two studies were conducted to evaluate the effect of phytase supplementation on the overall performance and nutrient retention efficiency of rainbow trout (Oncorhynchus mykiss) fed low-phosphorus (P) plant-based diets at water temperatures of 11 °C and 15 °C. In the first experiment at 11 °C, trout (average weight 56g) were allocated to one of 4 dietary treatments, with 3 replicate 200L tanks per diet and 35 fish per tank. In the second experiment (15 °C), trout (average weight 42g) wer...

Abstract Microbial biofilters control water quality and enable the overall function of recirculation aquaculture systems (RAS). Changes in environmental conditions can affect the abundance and interactions of the diverse microbial populations of the biofilter, affecting nitrification of harmful ammonium and thus fish health. Here, we examined the effect of different application frequencies (0, 1, 2 and 4 times per week) of a common disinfectant, peracetic acid (PAA, applied 1.1 mg l−1 twice per ...

Abstract The broad temperature range on the temperate coast of Korea has led fishermen to develop a unique and specialized procedure for the longline culture of ascidians. In Korea, warming of the coastal sea in winter has accelerated over the past few decades. After warmer winters, the rising temperatures of earlier springs have precluded the rearing of the ascidian spat in the culturing area and have imposed spring spat cultivation in colder-water nursery grounds. To examine the seasonal dynam...
Abstract Manganese (Mn) is an essential micronutrient for animals. An 8-week feeding experiment with oriental river prawn Macrobrachium nipponense was conducted to determine the effects of Mn supplementation on growth, antioxidative indices, intestinal morphology, and gut microbiota in juveniles of this species. Manganese sulfate monohydrate was added to a basal semi-purified diet at six levels: 5.4 (control), 13, 22, 34, 73 and 150 mg Mn kg−1 diet. Each diet was fed to juvenile prawns (mean wei...
