 “An affordable and easy-to-use tool for automatic fish length and weight estimation in a mariculture cage (AI FISH)”

In this study, 144 red swamp crayfish (Procambarus clarkii, initial mean weight 3.9 ± 0.3 g) juveniles were fed diets containing graded levels of purslane (Portulaca oleracea), with a decreasing percentage of proteins (from 17.3% to 1.0%) for 10 weeks. Six diets were administered: four fishmeal diets containing 5%, 15%, 25%, and 50% purslane, a diet with 100% purslane, and a commercial diet. Growth performance and the amounts of fatty acids and carotenoids were measured.

This study highlights that the environmental burden associated with seed production could be reduced by switching to alternative technologies to meet energy needs, such as investments in photovoltaic and wind energy production systems.

The present paper aimed at comparing electrical stunning (ES) and cold shock (ICE) in Salmo carpio, an Italian endemic under-investigated species. Rigor mortis evolution, fillet adenosine 5′-triphosphate (ATP), shape, colour, pH and water holding capacity were assessed by integrating chemical and image analyses.

In this study, we explore a promising way to take fish measurements in a non-invasive approach through computer vision.
Images captured by a stereoscopic camera are used by Artificial Intelligence algorithms in conjunction with computer vision to automatically obtain an accurate estimation of the characteristics of fish, such as body length and weight.

This study examined the environmental performance of mussel (Mytilus galloprovincialis) farming in the view of reduction of greenhouse gas emissions, through the Life Cycle Assessment (LCA) methodology.



2021 – Valore nutritivo e sicurezza alimentare di ingredienti innovativi o sotto-utilizzati di interesse per l’acquacoltura

A 10-week feeding trial was carried out to emphasize the effects of purslane weed (Portulaca oleracea) whole diet on pigmentation and fatty acids profile of juvenile freshwater red swamp crayfish Procambarus clarkii.

Procambarus clarkii is a native species of Central America, but strongly invasive in many
regions of the world. An investigation on the red swamp crayfish was carried out to obtain more information about its population dynamics in the Tiber River, in Central Italy.

The pattern of yellowish pigmentation of the skin was assessed in gilthead seabream (Sparus aurata) fed for 12 weeks iso-proteic (45%) and iso-lipidic (20%) diets deprived of fish meal and containing either a blend of vegetable protein-rich ingredients or where graded levels of the vegetable protein blend were replaced by insect (Hermetia illucens—10%, 20% or 40%) pupae meal, poultry by-product meal (20%, 30% or 40%), red swamp crayfish meal (10%) and marine microalgae (Tisochrysis lutea and Tetraselmis suecica—10%) dried biomass.

European consumers prefer wild over farmed aquatic food and consider it healthier and tastier. Consumers are increasingly paying attention to sustainability and welfare of farmed fish. Such expectations might be met by organic certification, but this represents a cost for the producer. It is crucial to know consumer habits about farmed aquatic food consumption and willingness to pay for certification.

The present study aims a comprehensive description of the Italian organic aquaculture sector, within the national aquaculture framework, in terms of production units and volumes during the four years period 2015-2018. This survey allowed to collect results about species produced and farm number and distribution at regional level.

2018 – Il consumo di pesce allevato e biologico in Italia

Il consumo di pesce allevato e biologico in Italia

A method for fish monitoring by high-frequency acoustic camera, coupled with an automated method for counting fish, was implemented that allowed to analyze very large amounts of data with reduced costs. The acoustic camera was mounted in the tidal channel of the Caprolace lagoon (central Italy) and programmed for 12 h. continuous recording at night time, between October 2016 and February 2017, for a total of 413 h, that were automatically processed by a specific software routine.

2017 – Acquacoltura Biologica

Acquacoltura Biologica: Opportunità e debolezze del settore

The majority of organic marine fish farms currently begin the production cycle with nonorganic juveniles from conventional hatcheries, permitted by the European Regulation on organic fish origin (EC 710/2009) until the end of 2016. Wild juvenile gilthead seabream (Sparus aurata) from coastal lagoons and hatcheries were experimentally reared under organic conditions, in order (1) to investigate differences in fillet lipid content and fatty acids composition, and (2) to propose a possible future source of juveniles destined for organic aquaculture.
