“…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

“…Increased deposition of LC-PUFA within white bass ova may have increased larval needs for protection from oxidative damage during this sensitive growth phase. Nonetheless, embryonic survival and hatch rate have been used as leading indicators of reproductive success in many broodstock trials evaluating dietary impacts as larval survival is often independent of broodstock dietary intake (Harrell and Woods 1995;Fernandez-Palacios et al 1995;Lane and Kohler 2006;Jaya-Ram et al 2008). Additional research is needed to link broodstock dietary intake and ovum composition to improved larval survival throughout the endogenous feeding period.…”

We evaluated white bass ovum fatty acid composition as well as embryonic and larval survival after varying n-3 and n-6 long-chain polyunsaturated fatty acid (LC-PUFA) concentrations in maternal diets. Diets containing graded levels (0, 33, 66, or 100%) of squid to menhaden oils were fed daily to apparent satiation to female white bass for 8 weeks prior to spawning. Embryonic survival was negatively related to maternal squid oil intake (P=0.015, R2=0.970). Squid oil-fed broodstock produced ova with decreased 20:5n-3 and increased C18 polyunsaturated fatty acid concentrations, largely reflecting the fatty acid profile of squid oil. Within ovum phospholipid, accumulation of 18:2n-6 may have altered biological function resulting in the lower embryonic survival among ova produced from the squid oil-fed broodstock. Our data suggest the importance of feeding white bass broodstock diets high in total n-3 LC-PUFA (at least 4.0% dry matter), and 20:5n-3-rich lipid sources such as menhaden oil can be effectively utilized by female white bass to produce quality ova.

“…HUFA and higher n-3 : n-6 ratios than eggs from equivalent cultured populations (Ashton et al, 1993;Harrell and Woods, 1995). 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).…”

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.
