The development of techniques to reduce stress in the aquaculture industry is essential for the good growth, low mortality, and high flesh quality of farmed fish. Shochu is a traditional Japanese alcoholic beverage, and the disposal of large amounts of Shochu lees waste has been a problem. As Shochu lees contain low-molecular-weight compounds, which are thought to have health benefits, the lactic acid-fermented by-product of Shochu distillery (FBPSD) was tested to estimate its anti-stress effects in neuropeptide Y-knockout zebrafish (NPY-KO), which exhibit high anxiety and low sociability, as a farmed fish model.In the Black-White preference test, NPY-KO preferred the black area over the white area due to fear, whereas NPY-KO fed the FBPSD showed a higher preference for the white area with more swimming distance than the control group. In the 3-chambers test, NPY-KO showed low sociability with the unfamiliar zebrafish group, whereas FBPSD-fed NPY-KO showed high sociability with the group. The mRNA level of isotocin, the homologue of human oxytocin, was significantly increased in the brains of FBPSD-fed zebrafish. The oxytocin receptor antagonists L-368,899 attenuated the effects of FBPSD in the 3-chambers test. These results suggest that FBPSD attenuates anxiety in NPY-KO zebrafish by activating isotocin neurons.

The density of microalgae and nutrient content have impact on the population growth rate, egg rate and nutritional values of rotifers. The aim of this study was to investigate the effects of different concentrations of the alga Nannochloropsis sp. (N10: 10x106, N20: 20x106, N30: 30x106 cells mL-1) on the growth, egg rate, biochemical composition and fatty acid profile of the rotifer Brachionus plicatilis. To maintain a consistent algae density, an equivalent quantity was supplemented to compensate for any reduction. The study was started with three replicates, each with an initial inoculation density of 200 Brachionus individuals mL-1 . The investigation spanned 5 days, during which population parameters (total number of individuals, proportion of individuals with eggs and growth rate) were calculated. After the study period, rotifers were harvested for subsequent biochemical and fatty acid analyses. Notably, the N30 group showed the highest proportions of crude protein (54.41%) and crude lipid (34.5%). The N20 group displayed the most substantial content of total fatty acids, recording a value of 70.69%. Consequently, the N30 group, with a concentration of 30x106 cells mL-1, emerged as the most proficient group, demonstrating superior performance in both population growth and biochemical composition.
