Sustainable Intensification of Aquaculture through Nutrient Recycling and Circular Economies: More Fish, Less Waste, Blue Growth

Camilla Campanati, David Willer, Jasmin Schubert, David C. Aldridge

Summary: Aquaculture has rapidly grown to meet the increasing global demand for seafood, but intensification of aquaculture has led to more pressure to find sustainable practices for resource conservation and waste reduction. Opportunities for wastewater treatment and by-product recovery exist through nutrient recycling, but further research is needed on harvesting methods and energy generation from by-products to support sustainable intensification.

Systematic review and meta-analysis of production performance of aquaculture species fed dietary insect meals

Hung Quang Tran, Tram Thi Nguyen, Marketa Prokesova, Tatyana Gebauer, Hien Van Doan, Vlastimil Stejskal

Summary: This study conducted a systematic review and meta-analysis to investigate the effects of insect meal on the growth performance of aquatic animals. The results showed that using insect meal as a replacement for fishmeal could improve the special growth rate and feed conversion ratio of aquatic animals. Different insect meals had different correlations with the growth performance of aquatic animals. The inclusion of insect-derived chitin at low levels also supported the growth performance of marine fish species.

Summary: The acquisition of fish stress information is crucial for monitoring water quality, preventing diseases, and improving welfare. Traditional manual methods for monitoring fish stress are time-consuming and unreliable, while new intelligent methods provide opportunities for automatic recognition. The latest technologies are categorized into machine vision-based, sensor-based, and acoustic-based methods. Advanced sensors and machine learning techniques play a key role in accelerating the automation and intelligence of fish welfare monitoring technology.

Interactions and associated resistance development mechanisms between microplastics, antibiotics and heavy metals in the aquaculture environment

Zhen Li, Muhammad Junaid, Guanglong Chen, Jun Wang

Summary: Microplastics, antibiotics, and heavy metals in aquaculture environments have serious ecological and human health consequences. Microorganisms develop antibiotic resistance genes and metal resistance genes as a defense mechanism. Heavy metals may lead bacteria to employ antibiotic resistance, while microplastics could act as potential carriers of multidrug-resistant genes.
