Feeding regimes affected the circadian rhythms of pancreatic digestive enzymes and somatic growth in flathead grey mullet (Mugil cephalus) fry

Growth performance is a key performance indicator of economic importance in animal production that is influenced by many different factors. Among them, feeding protocol is
among the most important ones.
Within this study, researchers analyzed the effect of different feeding regimes on the circadian rhythms of pancreatic digestive enzyme activities in Grey Mullet.

Histological evaluation of sex differentiation and early sex identification in hatchery-produced greater amberjack (Seriola dumerili) reared in sea cages

NewTechAqua researchers studied the sex differentiation process and the resulting sex ratio of greater amberjack produced entirely under aquaculture conditions. Such analysis is essential to ensure that rearing conditions do not lead to deviations from the natural sex ratios occurring in the wild.

The importance of thermoperiod for proper gametogenesis and successful egg and sperm production in meagre (Argyrosomus regius) breeders in aquaculture

In this study, the researchers involved in NewTechAqua project examined the possibility of using constant water temperature throughout the year (supplied by borehole water) to stimulate gametogenesis, and result in spawning of good egg/sperm/embryo in meagre (Argyrosomus regius).

If successful, this protocol could be implemented in broodstock management facilities, saving cost from heating and cooling the water in order to provide the expected natural water temperature for reproductive maturation.

Biosensors Based on Isothermal DNA Amplification for Bacterial Detection in Food Safety and Environmental Monitoring

The easy and rapid spread of bacterial contamination and the risk it poses to human health makes evident the need for analytical methods alternative to conventional time-consuming laboratory-based techniques for bacterial detection.

To tackle this demand, biosensors based on isothermal DNA amplification methods have emerged, which avoid the need for thermal cycling, thus facilitating their integration into small and low-cost devices for in situ monitoring. This review focuses on the breakthroughs made on biosensors based on isothermal amplification methods for the detection of bacteria in the field of food safety and environmental monitoring.
