“…Eggs from field-collected striped bass were slightly larger and in 1 year (1999) had slightly higher total lipid than the hatchery controls. Other studies have reported similar findings, indicating that river-collected striped bass eggs were of higher quality than hatchery eggs (18,19).…”

Aquatic ecosystems around the world face serious threats from anthropogenic contaminants. Results from 8 years of field and laboratory investigations indicate that sublethal contaminant exposure is occurring in the early life stages of striped bass in the San Francisco Estuary, a population in continual decline since its initial collapse during the 1970s. Biologically significant levels of polychlorinated biphenyls, polybrominated diphenyl ethers, and current-use/legacy pesticides were found in all egg samples from river-collected fish. Developmental changes previously unseen with standard methods were detected with a technique using the principles of unbiased stereology. Abnormal yolk utilization, brain and liver development, and overall growth were observed in larvae from river-collected fish. Histopathological analyses confirmed and identified developmental alterations. Using this methodology enabled us to present a conclusive line of evidence for the maternal transfer of xenobiotics and their adverse effects on larval striped bass in this estuary.Morone saxatilis ͉ contaminants ͉ biomarkers ͉ histopathology ͉ unbiased stereology

“…Eggs from cultured Atlantic salmon had an increased level of 20:5n-3 and a decreased level of 20:4n-6 which greatly increased the ratio of 20:5n-3 : 20:4n-6 in the cultured eggs as compared to wild eggs (Pickova et al, 1999). Decreased 20:4n-6 in eggs from cultured fish in comparison with wild fish was also observed in striped bass (Gallagher et al, 1998). In contrast, the above study with…”

“…The polar lipids of most fish eggs are dominated by phosphoglycerides, particularly PtdCho, followed by PtdEtn, PtdSer and PtdIns. Exceptions to this pattern are striped bass eggs, whose phospholipids are reported to contain predominantly PtdIns (Gallagher et al, 1998), and sturgeon eggs, which have relatively high PtdEtn (Gershanovich, 1991). The neutral lipids are mainly triacylglycerols with smaller amounts of cholesterol although some lipid -rich eggs have globules that are predominantly steryl and/or wax esters as in gourami or some freshwater Perciformes and striped bass (Anderson et al, 1990;Wiegand, 1996a).…”

Lipids and their constituent fatty acids are, along with proteins, the major organic constituents of fish, and they play major roles as sources of metabolic energy for growth including reproduction, and movement including migration. Furthermore, the fatty acids of fish lipids are rich in ω3 long chain, highly unsaturated fatty acids (n-3 HUFA) that have particularly important roles in animal nutrition, including fish and human nutrition, reflecting their roles in critical physiological processes. Indeed, fish are the most important food source of these vital nutrients for man Thus, the long standing interest in fish lipids stems from their abundance and their uniqueness. This review attempts to summarise our present state of knowledge of various aspects of the basic biochemistry, metabolism and functions of fatty acids, and the lipids they constitute part of, in fish, seeking where possible to relate that understanding as much to fish in their natural environment as to farmed fish. In doing so, it highlights the areas that require to be investigated in greater depth and also the increasing application of molecular technologies in fish lipid metabolism which will fascilitate further advances through molecular biological and genetic techniques including genomics and proteomics.

“…Others have reported that 18:1n-9 is the most common fatty acid in sturgeon and other fish eggs and tissues [6,26,[29][30][31][32][33]. The results of this study show that MUFAs were higher in wild than in domestic beluga.…”

“…The amount of linoleic acid (18:2n-6) was much greater in the cultivated beluga eggs than in wild ones. The same tendency was also found in the lipid profile of ovulated eggs of wild and cultured turbot (Scophthalmus maximus) [30], striped bass (Morone saxatilis) [32] and white sturgeon [6] and is a reflection of dietary fat intake [2,6,11,30]. In addition, Hosseini et al [33] compared the effect of three different diets including fish oil, soybean oil and canola oil on muscle fatty acids profiles in cultivated beluga (H. huso).…”

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...
