REPRODUCTION | NUTRITION

Soy isoflavones could become a tool for sex differentiation in some aquaculture fish species

Global, 11 August 2026 | Genistein has shown an ability to alter sex ratios in different fish species, although responses are not consistent

TECHNOLOGY | QUALITY AND TRACEABILITY

From water quality to fish freshness: nanosensors point towards continuous monitoring across the aquaculture value chain

Taiwan, 11 August 2026 | A scientific review suggests that the same compounds that signal deteriorating conditions in farming water could be used to anticipate quality losses after harvest, although the technology must still prove reliable under real production conditions

REPRODUCTION | AQUACULTURE DIVERSIFICATION

New data show that captive-born Senegalese sole experience disruption across their entire reproductive axis

Lugo, Spain, 10 August 2026 | The first integrated analysis of the hypothalamus, pituitary and gonads finds the greatest differences from wild-origin fish in the centres responsible for hormonal control of reproduction, shifting attention away from a single cause located in the testes

AQUACULTURE BUSINESS RADAR | GENETICS, RAS AND CIRCULARITY

Aquaculture companies: Troutlodge refines genetic selection, Superior Fresh replicates its model and Atlantic Sapphire enters a new phase

This week’s Aquaculture Business Radar highlights four signals shaping the sector: genetics, aquaponic salmon, circularity and RAS financing. The common thread: aquaculture competitiveness is moving beyond volume towards data, scalability, resource recovery and financial resilience.

Invest in Spain

Acuicultura Cádiz | @misPeces

Three greater amberjack projects in Spain mobilise around €18 million in public funding

Madrid, 6 August 2026 | The funding supports a hatchery in Carboneras (Almería) and two RAS grow-out facilities in Alicante and Cádiz

NUTRITION | NOVEL INGREDIENTS

Fermentation improves the protein profile of Ulva as a feed ingredient for European seabass

El Puerto de Santa María, 6 August 2026 | The trial, carried out within the European NOVAFOODIES project, shows that fermented biomass can increase protein concentration and reduce carbohydrates, although high inclusion levels affected growth in juvenile seabass

CONSUMPTION | CERTIFICATION AND VALUE

Certification is not enough: lack of information prevents sustainable farmed shrimp form generating greater value in supermarkets

Santander (Spain), 5 August 2026 | A study conducted across five Spanish retail chains confirms that the ASC label has no significant effect on price, while explaining its meaning increases consumers stated willingness to pay

HATCHERIES | LIVE FEED

Dependence on wild Artemia threatened the future supply of aquaculture hatcheries

Global, 4 August 2026 | The World Bank estimates that global cyst demand could exceed 5,000 tonnes by 2035, compared with approximately 3,500 tonnes today, and proposes expanding production in saltworks and hypersaline ponds

ANALYSIS | AQUACULTURE NUTRITION

Can hydrolysates improve aquafeeds without increasing the cost of the fish produced?

Global, 3 August 2026 | The industry is investing in converting by-products into functional ingredients capable of supporting feed intake, digestibility and the performance of diets containing less fishmeal, although public data demonstrating their profitability over an entire production cycle remain scare

EMPLOYMENT | EQUALITY AND PROFESSIONAL DEVELOPMENT

Women account for only 22% of European aquaculture employment, with Mediterranean participation still concentrated in certain activities

Brussels, 3 August 2026 | Shellfish farming, technical roles and research provide important areas of participation, but women remain under-represented in fish production, sea-cage operations and senior decision-making positions

BIOTECHNOLOGY | ANIMAL HEALTH

A food-grade bacterium opens a non-GM route for delivering antigens to shrimp

Thailand, 3 August 2026 |

IN-DEPTH

ANALYSIS | AQUACULTURE NUTRITION

Can hydrolysates improve aquafeeds without increasing the cost of the fish produced?

NUTRITION | AQUAFEEDS

EU protein plan opens opportunities for aquafeeds but leaves the sector outside its core measures

Brussels, 13 July 2026 | The European strategy could increase the availability of local and circular ingredients, but it does not guarantee that aquaculture will gain access to cheaper proteins

Science-to-business | FEEDS

Microalgae in aquafeeds: how much can realistically be included and what return can farmers expects?

Luxembourg, 3 July 2026 | In terms of total inclusion, the European Commission considers technically feasible ranges of 10% to 15% algae-based ingredients in salmon and trout feeds, and 20% to 25% in feeds of European seabass and gilthead seabream.

INTERVIEW

The importance of trial units at BioMar’s R&D centres for the development of efficient and profitable aquafeeds

Iannis Karacostas explains to misPeces how trial units help refine the nutritional requirements of species such as European sea bass, gilthead sea bream and rainbow trout, with the aim of improving growth, feed conversion, product cost and profitability for producers
