1. Introduction
The yellowfin tuna (Thunnus albacares) is an ecologically and commercially important fish species that is widely distributed throughout the tropical seas (Collette and Nauen, 1983). Yellowfin tuna are top predators that feed on forage fish, squid, and pelagic crustaceans, among other organisms (Alverson, 1963; Essington et al., 2002). Yellowfin tuna possess many unique specializations including internalized red muscle and vascular counter-current head exchangers, and they have slightly elevated metabolic rates relative to most fishes (Graham, 1975; Dizon and Brill, 1979; Korsmeyer and Dewar, 2001; Blank et al., 2007a; Klinger et al., 2016). There is a strong international demand for yellowfin tuna for human consumption, and there are concerns about the effects of fishing pressure on some populations (Minte-Vera et al., 2014). In the eastern Pacific Ocean where the yellowfin tuna in this study were collected, purse seining is the most common type of fishing gear, though longline and pole-and-line techniques are also used (Hoyle and Maunder, 2005). The majority of purse-seining operations rely on fish aggregating devices (FADs) to capture yellowfin tuna, an activity that has been shown to have high bycatch rates of non-target species (Fonteneau et al. 2000). Due to concerns about overfishing, bycatch, and an increasing international demand for tuna, some groups have experimented with raising yellowfin tuna in aquaculture scenarios. Proponents of tuna aquaculture cite the potential for reduced fishing pressure on wild tuna populations, elimination of bycatch, and a more efficient economic system relative to capture-based fisheries (Zertuche-González et al., 2008). However, tuna aquaculture has been criticized for effluent contamination of coastal waters, a large carbon footprint, and overconsumption of feed species (i.e. clupeids) resulting from high food conversion ratios (FCRs) (Volpe, 2005; Zertuche-González et al., 2008). Commercial scale tuna aquaculture began in the 1960s with Atlantic bluefin tuna (Thunnus thynnus), and currently large-scale developments exist for all three bluefin tuna species (including Thunnus orientalis and Thunnus maccoyii) in Australia, Mexico, Japan, and throughout the Mediterranean Sea (Metian et al., 2014). Aquaculture of bluefin tuna has been dominated by capture-based systems in which juvenile and adult tuna are collected in the wild, maintained in ocean pens where they are fattened with a diet of wild forage fish, and later harvested for market (Lioka et al., 2000; Ottolenghi, 2008; Klinger et al., 2013). Scientists at Kindai University in Japan, however, were the first to develop a closed-lifecycle approach, collecting fertilized eggs from broodstock tuna and growing them into market size bluefin tuna (Sawada et al., 2005). Despite these advances in understanding the spawning cycle and life history of tunas, capture-based operations continue to dominate bluefin tuna aquaculture production
