“…These physiological traits may underlie thermal-niche expansion of BFT and PBT relative to tropical tuna species (Blank et al, 2007). The results and conclusions of this study may appear contradictory with those for energy requirement of YFT broodstock (Wexler et al 2003) (Wilson, 2002). Water temperature is another factor that could affect the protein requirement.…”

“…The energy needs of YFT broodstock were predicted based on oxygen and caloric requirements as functions of tuna size and water temperature, with fish increasing caloric intake with increasing size, resulting in caloric consumptions ranging from 9 to 104 kcal kg (Wexler et al, 2003).. Recent studies at the University of Kinki in Japan with juvenile PBT have shown that starving fish of 0.85 g over 4 days induced severe damage and mortalities of over 90% (Takii et al, 2005).…”

“…The possibility that intact phospholipids, particularly phosphatidylcholine and phosphatidylinositol, in addition to the vitamins choline and inositol, may also have a growth promoting effect in diets for larval tuna as they have in other marine fish species is an aspect that will require study at some point. A mixed vitamin formulation supplied at a level of 0.5 -1.5 % of the weight of the feed plus 500 mg vitamin C fish -1 day -1 were used to feed YFT broodstock in captivity (Wexler et al, 2003). Moreover, practical evidence with SBT suggests that enriching and/or fortifying with a vitamin premix is particularly important when using a poorer quality whole fish feed (not fresh and/or rancid) and/or when the fish are in poor condition.…”

“…), 30 % jack mackerel (Trachurus japonicus), 10 % squids (Decapterus tabl, Todarodes pacificus) and 3 % sardines (Sardinops melanosticus) (Sawada et al, 2005). Similarly in Panama, YFT broodstock are fed on local baitfish and squids including Pacific anchoveta (Cetengraulis mysticetus), bigscale anchovy (Anchovia macrolepidota), market squid (Loligo opalescens), and Argentine shortfin squid (Illex argentinus) (Wexler et al, 2003). The daily rations for YFT broodstock ranged from 1 % to 10 % body weight day -1 and showed FCRs that varied from 10.9 to 34.6 on a wet weight basis, with an average of 18.2.…”

Aquaculture is providing an ever-increasing proportion of fish in the human food basket prompting a search for new species to expand the range available to consumers. Large tunids/scombrids have long-since been a very valuable resource providing not only high quality protein, but also a rich source of the highly beneficial omega-3 (or n-3) long-chain polyunsaturated fatty acids including eicosapentaenoic and, especially docosahexaenoic acids in the human diet. Consequently, there is considerable interest worldwide in developing the culture of large tunids, including Atlantic northern bluefin tuna (Thunnus thynnus), Pacific bluefin tuna (Thunnus orientalis), southern bluefin tuna (Thunnus maccoyii) and yellowfin tuna (Thunnus albacares). Nutrition is vital to this development, playing key roles in reproductive success, including the establishment of successful broodstock producing high quality eggs and larvae, and ultimately the cost-effective production of nutritious seafood.This review summarises the rather fragmentary data that compromise the current state-of-theart in relation to tuna nutrition and the development of artificial, formulated feeds for these species. In highlighting the various considerable challenges that feed development will pose, we discuss the future perspectives for tuna culture in terms of both fish and human nutrition and welfare, against the background of diminishing global marine resources.3

“…In addition, the use of animal by-product meals and fats continues to increase . However, in the natural environment, salmon feed primarily on other fish and crustaceans (Jacobsen and Hansen 2001 (Wexler et al 2003). As a general rule, only 10% of the energy from a trophic level is captured as biomass in the next higher trophic level (Welch et al 2010).…”

Long‐chain omega‐3 from low‐trophic‐level fish provides value to farmed seafood

Low-trophic-level fish are a crucial source of long-chain (LC) omega-3 fatty acids for farmed fish and humans. Many farm-raised fish species have a clear need for these nutrients. Farmed fish deposit the LC omega-3s in their flesh and transfer them up the food chain. However, the content of LC omega-3s in farm-raised seafood continues to decline, while the content of shorter-chain plant-sourced omega-3s, and pro-inflammtory omega-6s continue to increase. This reduces its nutritional worth. The value of low-trophic-level fish is often viewed merely as its price at the dock. Some reports and metrics steer public attention towards the mass balance between quantities of low-trophic-level fish and farmed seafood. However, the the nutritional value of seafood is more important than its mere quantities. The role of low-trophic-level fish in human nutrition, health, and wellbeing is a fundamental component of its economic value to society.
