Shrimp are one of the most widely cultivated aquaculture commodities, accounting for up to 55% of the total global shrimp production (FAO, 2020). Within the sector, the demand for whiteleg shrimp (Litopenaeus vannamei) has continued to increase – to the point that the market’s needs are no longer matched by the current supply. One of the main obstacles facing shrimp farmers is the availability of high-quality seed from hatchery operations. Alongside considerable differences in seed quality, these producers are encountering a great deal of unpredictability with regards to both biological performance and disease/contamination risks (specific pathogen-free). Furthermore, low-quality seeds can cause failure or losses in shrimp aquaculture systems, including slow growth, non-uniform size and increased sensitivity to changes in water quality and the production environment (Wei et al., 2014). With most seeds produced in hatcheries, the availability of excellent broodstock is a critical factor in establishing high quality.

Conventional aquaculture systems From a sustainability perspective, the development of the aquaculture industry faces fundamental challenges because the cultivation techniques used for broodstock production are still dominated by conventional systems using semi-batch, flow-through,

and outdoor earthen pond systems. These conventional cultivation systems are still widely used because the technologies are relatively simple with low operational costs, and continue to be profitable. Nevertheless, from a long-term standpoint, these conventional aquaculture systems cannot continue to dictate the sector – not least because of their inability to control water quality and prevent disease. In addition, conventional systems tend to produce low quality and quantities of seed. Hence, alternative technologies for broodstock production need to be developed and implemented as a progressive strategy to enhance the overall sustainability of shrimp aquaculture (Eng et al., 1989; Otoshi et al., 2003; Suantika et al., 2018).

NOVATON closed aquaculture system One alternative for high-quality broodstock production is the application of the NOVATON Closed Aquaculture System. This environmentally-friendly system is designed to reproduce the optimal conditions to grow selected crops. It includes the specific conditioning of water, salinity and temperature while offering high levels of biosecurity and animal welfare, alongside effective waste management. NOVATON’s aquaculture technology stems from the evolution and combination of different methodologies to cultivate shrimp in closed environments together with new cleantech equipments that manage the
