“…The two-part model has been employed in fields such as health ( Dean et al., 2020 ; Lartey et al., 2020 ) and agriculture ( Dehghan et al., 2020 ; Ruhinduka et al., 2020 ). Gutiérrez et al. (2020) , Ramalho and da Silva (2009) and Wulff (2019) used two-part models to model DEA scores in aquaculture and dairy respectively.…”

A large body of literature exists on analysis of citation and reviews of application of efficiency frontier. However, the reviews that assessed the determinants of citation counts did not focus on frontier applications. We contribute to the literature by identifying the drivers of citations of frontier application publications on Ghana. We employed two-part mixture modelling with inverse hyperbolic sine (IHS) transformation of the second part, which was found to be more appropriate than single equation IHS transformation modelling, for our data. Use of stochastic frontier analysis or data envelopment analysis did not drive citations counts. However, quality of journals in which frontier application studies were published and accessibility of the journals to readers, drive citation counts. Authors, institutions and funders of studies on frontier applications may consider these over collaborations, in seeking growth in citation counts.

“…By 2016, the aquaculture relevance as an animal protein source was underlined by its huge global production that reached nearly 80 million tons. Among the European countries, Spain is expected to reach more than 0.3 Mt of annual production [ 137 ]. This exponential growth has been prompted by the low feed conversion ratio that aquaculture species exhibit, 1.1–1.6 kg of feed/kg of edible fish, against livestock, which can reach maximum ratios of 9 kg of feed/kg of beef [ 138 , 139 ].…”

The Use of Invasive Algae Species as a Source of Secondary Metabolites and Biological Activities: Spain as Case-Study

In the recent decades, algae have proven to be a source of different bioactive compounds with biological activities, which has increased the potential application of these organisms in food, cosmetic, pharmaceutical, animal feed, and other industrial sectors. On the other hand, there is a growing interest in developing effective strategies for control and/or eradication of invasive algae since they have a negative impact on marine ecosystems and in the economy of the affected zones. However, the application of control measures is usually time and resource-consuming and not profitable. Considering this context, the valorization of invasive algae species as a source of bioactive compounds for industrial applications could be a suitable strategy to reduce their population, obtaining both environmental and economic benefits. To carry out this practice, it is necessary to evaluate the chemical and the nutritional composition of the algae as well as the most efficient methods of extracting the compounds of interest. In the case of northwest Spain, five algae species are considered invasive: Asparagopsis armata, Codium fragile, Gracilaria vermiculophylla, Sargassum muticum, and Grateulopia turuturu. This review presents a brief description of their main bioactive compounds, biological activities, and extraction systems employed for their recovery. In addition, evidence of their beneficial properties and the possibility of use them as supplement in diets of aquaculture animals was collected to illustrate one of their possible applications.

“…As a result of their limited shelf-life, live mussels can only be transported a few hundred kilometres from the coast, requiring a fast and efficient logistic network. The aquaculture sector is more efficient where there is an established and well-functioning seafood value chain (Gutiérrez et al 2020). The existence of traditional consumption and markets is perceived as an important strength in Spain, France, Italy, Greece, Germany, Portugal, Bulgaria, Croatia and Slovenia.…”

In contrast to the increasing aquaculture production of mussels worldwide, production in the European Union (EU) has shown a decreasing trend over the last two decades. Aquaculture production of mussels in the EU peaked in the late 1990s at more than 600 000 tonnes; by 2016, production volume had dropped by 20% to 480 000 tonnes. As mussel production represents more than ⅓ of EU aquaculture production, this decrease is an important contributor to the stagnation of EU aquaculture. Previous studies have suggested diseases, lack of mussel seed (spat), and low profitability as the main causes of the EU mussel production decrease. In this study, we investigate how economic and environmental factors have contributed. Moreover, we examine if the different mussel production techniques (raft, longline, on-bottom, and 'bouchot') have been differently affected, by analysing the economic performance and cost structure evolution for the period 2010-2016. We complement these results with a SWOT (strengths, weaknesses, opportunities, and threats) analysis of the EU mussel sector based on expert knowledge.
