This study evaluates the potential of near-infrared spectroscopy (NIRS) as a rapid and cost-effective technique for estimating the fatty acid profile of Senegalese sole (Solea senegalensis). Traditionally, lipid profiling in aquaculture products has relied on gas chromatography (GC), a highly accurate but time-consuming, costly and complex method r...

Effluents generated in aquaculture could contribute to increased risk of environmental contamination. Aquaponic could facilitate the resolution of this problem by transforming those potential pollutants into nutrients for plants, providing an extra vegetable production in a circular economy framework. Highly profitable vegetables such as pitaya (Hy...

Indoor air pollution is a serious health problem throughout the world. Plants are known to be able to reduce the effect of air pollution and improve indoor air quality (IAQ). The aim of the present study was to compare the effectiveness of four plant species (Tradescantia zebrina hort. ex Bosse, Philodendron scandens K. Koch & Sello, Ficus pumila L...

Homestead aquaponic production has been proposed as a reasonable alternative for obtaining food within the framework of the circular economy. However, little is known about the ability of homestead aquaponics to contribute to a healthy diet and the savings it represents on the cost of such diets for inhabitants of economically depressed communities...

The methods used to evaluate kinetic parameters of ruminant feeds can be in situ and in vitro. For both methods, it is necessary to maintain cannulated animals in order to collect the inoculum from the rumen, which has been under strong pressure from society, in terms of animal welfare policies, to avoid this type of practices. This work aimed to e...

Elephant grass is a tropical forage widely used for livestock feed. The analytical techniques traditionally used for its nutritional evaluation are costly and time consuming. Alternatively, Near Infrared Spectroscopy (NIRS) technology has been used as a rapid analysis technique. However, in crops with high variability due to genetic improvement, pr...

Fusarium wilt is one of the most widespread diseases in carnation crops in a large number of countries. Plant protection products commonly used to remedy the disease have been considered ineffective and environmentally unsafe for commercial use. As an alternative, the use of suppressive growth media has been proposed. The aim of this study was to e...

Aquaponics is a sustainable food production system combining hydroponics and aquaculture.

The objective of this study was to determine the profile and motivations of aquaponic producers, the characteristics of the...

Aquaponics is emerging as an interesting alternative for sustainable agriculture which meets the philosophy of circular economy, decreasing not only the need of external resources but also increasing their use efficiency. Several studies can be found dealing with the analysis of different fish species combined with a great variety of crops in syste...

Near Infrared (NIR) spectroscopy was evaluated as a fast and easy method for identifying the most interesting cocoa genotypes according to chemical composition, including bioactive compound contents, in more than 80 samples of cocoa beans from the Mexican Germplasm Bank, which were harvested over three years. Clear differences in chemical compositi...

Aquaponics is a productive system in which the production of vegetables and fish is synergistically combined within a circular economy framework. Although these systems have been in development for more than 50 years, the presence of aquaponic products in the markets is still very limited. Previous studies have been carried out trying to characteri...

Aquaponic systems combine fish (aquaculture) and plant production (hydroponics), mimicking a complex ecosystem. Though aquaponic facilities can be built for commercial purposes, the self-consumption perspective is also important. There is a gap in studies that evaluate the use of a large number of plant species produced in aquaponic systems for sel...

Waterborne diseases pose a significant risk in hydroponic crops, especially those caused by some species such as Fusarium, Pythium and Phytophthora. However, there is evidence of an increase in suppressiveness when using aquaculture effluents, as is the case with aquaponic systems. In this work, the incidence of diseases in hydroponic and aquaponic...

The potential of the cocoa bean husk (CBH) as a natural source of bioactive compounds is ever-increasing. In this work, its bioactive compounds and antioxidant activity were analyzed using near infrared spectroscopy in samples of CBH. Beans were harvested and fermented in a Mexican gene bank.

A portable near infrared spectroscopy (NIRS) instrument was evaluated for the discrimination of individual Iberian pig carcasses into the four official quality categories (defined by a combination of genotype and feeding regime). Spectra were obtained scanning four anatomical locations (live animal skin, carcass surface, fresh meat and subcutaneous...

Aquaponics is a farming technique that can be used in urban environments for the simultaneous production of plants (hydroponics) and fish (aquaculture). The fish consume the supplied feed and their waste is naturally converted to nitrate and other nutrients, which are then taken up by the plants, acting as a natural water filter. Regarding food saf...

Aquaponics is a developing technique that combines the simultaneous production of plants (hydroponics) and fish (aquaculture). With it, the use of resources (i.e., water, nutrients, land) is reduced whilst at the same time minimising residues’ discharge to the environment. Among its benefits, it allows the production of healthy vegetables and fish...

Soil fertility is typically assessed by chemical analysis, which is expensive and time-consuming, and hence impractical for site-specific fertilizer management. Visible and near infrared (Vis–NIR) spectroscopy has been used for determining soil properties and chemically extractable plant nutrients. However, the suitability of Vis–NIR for accurate a...

European small ruminant systems are mainly situated in mountain areas and for the production model to be sustainable, the quality of products and traceability should be analysed. Technical data and bulk milk samples (n = 48 for each season) from 16 goat farms were collected each month during the four seasons of the year. According to the indicator...

Sexual reproduction in olive is carried out for purposes such as breeding. The seedlings evolve from the juvenile to the adult stage, and until now, only the discrete developmental phases have been investigated in detail. However, the transition process has been poorly studied in fruit trees, especially in olive. In this paper, juvenile to adult tr...

The CD36 molecule plays a key role in the uptake of long-chain fatty acids. In a previous study, we demonstrated that the CD36 gene is duplicated in goats. Moreover, both copies (CD36 and CD36-like) display highly divergent mRNA expression profiles. Herewith, we have analysed wether four polymorphisms mapping to CD36 (c.394A > G, c.*141C > T and c....

Individual fatty acids contents together with the saturated (SFA), monounsaturated (MUFA) and polyunsatu...

Malic enzyme 1 plays a fundamental role in lipid metabolism because it yields a significant amount of the NADPH necessary for fatty acid biosynthesis. In ruminants, however, its contribution to this biochemical process seems to be less relevant than in other livestock species. In this study, we have partially sequenced the goat ME1 gene with the ai...

Wild rabbit meat is commonly consumed in many Mediterranean countries. However, the characteristics of the carcass and meat of this game species have been scarcely investigated. This study was aimed at analysing the chemical composition of hunted wild rabbit (Oryctolagus cuniculus algirus) meat from Southern Iberian Peninsula, and studying the viab...

Genetic variability of the caprine stearoyl-CoA desaturase 1 (SCD1) gene has been investigated by sequencing a 4.7-kb cDNA in 6 goats from the Murciano-Granadina and Malagueña breeds.
