“…FDC had significantly higher K, Na and P content (1179.9, 376.2 and 257.7 mg/100 g of sample, respectively) compared with those of BDC and SDC (P < 0.05). Similar K, P and Na contents in defatted-tuna roes were found in salmon roe (Bekhit et al 2009). P content has been generally associated with the phospholipid content and the presence of phosphoprotein (Mahmoud et al 2008;Matsubara et al 2003).…”

Roe is the term used to describe fish eggs (oocytes) gathered in skeins and is one of the most valuable food products from fishery sources. Thus, means of processing are required to convert the underutilized yellowfin tuna roes (YTR) into more marketable and acceptable forms as protein concentrate. Roe protein concentrates (RPCs) were prepared by cooking condition (boil-dried concentrate, BDC and steam-dried concentrate, SDC, respectively) and un-cooking condition (freeze-dried concentrate, FDC) from yellowfin tuna roe. The yield of RPCs was in the range from 22.2 to 25.3 g/100 g of roe. RPCs contained protein (72.3-77.3 %), moisture (4.3-5.6 %), lipid (10.6-11.3 %) and ash (4.3-5.7 %) as the major constituents. The prominent amino acids of RPCs were aspartic acid, 8.7-9.2, glutamic acid, 13.1-13.2, and leucine, 8.5-8.6 g/100 g of protein.Major differences were not observed in each of the amino acid. K, S, Na, and P as minerals were the major elements in RPCs. No difference noted in sodium dodecyl sulfate polyacrylamide gel electrophoresis protein band (15-100 K) possibly representing partial hydrolysis of myosin. Therefore, RPCs from YTR could be use potential protein ingredient for human food and animal feeds.

“…The highest S content was found in egg white (1341.3 mg/100 g) as a positive control (P < 0.05). Bekhit et al (2009) reported that salmon roe had S content of 1647-2443 mg/kg (wet basis). Catfish roe protein powder had S content of approximately 0.56 mg/kg (Sathivel et al 2009).…”

“…Amino acid compositions of defatted tuna roe powders were similar to those of mullet, cod, pollock and chinook salmon roe (Bekhit, Morton, Dawson, Zhao, & Lee, 2009;Bledsoe et al, 2003). Thus, protein-rich defatted-tuna roes could be an alternative source of amino acids with nutritive value.…”

“…Glutamic acid and aspartic acid were the amino acids in highest concentration in beluga roes ( Table 2). Glutamic acid and aspartic acid have been reported as the major components in fish roes by other researchers [3,26,37,38]. Beluga roes contain considerable serine as do other sturgeon roes [26,39].…”

A comparison of the fatty acid, amino acid and proximate composition between the roe of wild and cultivated beluga (Huso huso) sturgeon from Iran are presented here. The fatty acid profile varied between wild and cultivated sturgeons but there was no differences observed for proximate composition and amino acid profile. The wild sturgeon roe contained higher amounts of n-3 fatty acids particularly eicosapentaenoic acid (20:5n-3, EPA) (wild: 2.9%, cultivated: 1.24%) and docosahexaenoic acid (22:6n-3, DHA) (wild: 5.1%, cultivated: 2.38%). Linolenic and linoleic acids were the predominant fatty acids in roe from cultivated beluga, a reflection of diet and also a likely physiological adaptation to a higher temperature environment. Low levels of PUFA in cultivated sturgeon negatively affected fertilization and hatching ratios which were significantly lower than for the wild fish. Hence, in order to culture beluga, feed with higher fatty acid with more n-3 is necessary to reach high quality roe and fertilization and hatching ratio. parameters, have been used to determine egg quality, which are also affected by a nutritional deficiency in broodstock diets. Indeed, one of the major nutritional factors that have been found to significantly affect reproductive performance in fish is the dietary essential fatty acid content [9]. Selective retention of DHA has also been found during embryogenesis and during starvation denoting the importance of this fatty acid for the developing embryo and larvae.At present, studies available on lipid composition of cultured sturgeons are somewhat limited in the sense that they do not provide a comparison of cultured and wild beluga roe or meat [10][11][12][13][14][15][16]. Here, a comparison of the chemical composition (chemical, fatty acid and amino acid profiles) of the roe from farmed and wild caught beluga (H. huso) from the same watershed in the southern Caspian Sea is presented and how this may affect egg survival is presented. Materials and Methods Egg collectionWild beluga (H. huso) (Female: TL = 240 ± 40 cm, weight = 95 ± 7 kg; Male: TL = 180 ± 20 cm, weight = 82 ± 5 kg) were captured during their spawning season (February-March) on the south eastern coast of the Caspian Sea between Gorgan and Sari using gillnets fishing method and taken to the Marjani Hatchery Center (Gorgan, Iran). Eggs collected for the recruitment program were recovered from live fish that had been transferred to this hatchery. After 24 h adaptation, 50 g eggs from each five ovulating females were collected using surgically method, placed into separate 20 ml plastic containers and immediately frozen in liquid nitrogen. Simultaneously, ovulated eggs from cultured beluga (Female: TL = 190.6 ± 12.5 cm, weight = 94.6 ± 9.3 kg; Male: 160 ± 10 cm, weight: 73 ± 6 kg ) were collected at the Rajaee Sturgeon Hatchery Center, in Sari, Iran in 2009, a culture facility about 120 km far from Marjani and eggs were recovered from three females as described above. These fish had been reared in fresh, warm (19 ± 2ºC) ar...
