“…Numerous reviews have extensively detailed the work performed in fish welfare (Fraser 1993, Lehman 1998, Salzen 1998, Balon 2000, Broom 2001, Désiré et al 2002, Rose 2002, Rushen 2003, Chandroo et al 2004, Conte 2004, Sandoe et al 2004, Hastein et al 2005, Dawkins 2006a,b, Duncan 2006, Huntingford et al 2006, Veissier & Boissy 2006. Therefore, this review will focus mainly on the direction of future research on this issue.…”

Fish welfare issues are predicated on understanding whether fish are sentient beings. Therefore, we analyzed the logic of the methodologies used for studying this attribute. We conclude that empirical science is unable to prove or to disprove that fish are sentient beings. Thus, we propose a combined ethical-scientific approach for considering fish as sentient beings. The most difficult ongoing question is to determine which conditions fish prefer. Approaches to assess fish preferences should be rigorously and cautiously employed. In light of these considerations, attempts to establish physiological standards for fish welfare are discouraged, and a preference-based definition of fish welfare is proposed.

“…Changes in fishery resource community compositions is a central concept in research aimed at fishery resource conservation (Brotto and Araujo, 2001;Jan et al, 2003). Many studies have shown that AR play important roles in attracting nekton communities and promoting the aggregation and recovery of biological communities within their effective impact areas.…”

Marine habitat degradation resulting from human activities and environmental pollution has led to serious deterioration of marine fishery resources. To address this issue, countries worldwide are exploring sustainable fishery approaches. Installation of artificial reefs (AR) is rapidly increasing. AR have been widely constructed globally to conserve fishery resources and improve marine habitats. As an important biological group of marine fishery resources, nekton are widely evaluated to determine the effects of ecological restoration and resource conservation. In the current study, we compared the dynamic properties of taxonomic diversity and the eco-exergy of nekton community from 2 to 14 years after AR construction in Dalajia, China. The results indicated that the species number and density of nekton significantly increased after AR construction. Siganus oramin became an absolute dominant fish species in the reef area and its surroundings. The species diversity and evenness of the nekton community decreased, whereas species richness increased. The abundance, biomass, and eco-exergy of the nekton community increased over time because of the dominance of fishes. Our results highlight that AR can increase and conserve fishery resources, improve the structure of the nekton community, and increase ecosystem stability. But, at the same time, the dominance of S. oramin can interfere in the reef community. The explosive growth was quantitatively and qualitatively higher than that of other species, the diversity and evenness indices showed a decreasing trend, although the number of nekton species was significantly higher than that in the background survey and CA habitat during the same period.
