“…This observation confirmed the study by Bird et al (1993) that non-parasitic adult L. planeri relied on the larval diet and preferred to use shorter chain length FA in muscle TG. The observations in liver TG observed in naturally starved lamprey, P. marinus, are somewhat different from that reported in juvenile and adult lamprey (Whyte et al, 1993), trout (Jezierska et al, 1982) and sea bass (Delgado et al, 1994). This difference possibly suggests the existence of species specificity.…”

This study was designed to evaluate biochemical changes in the fatty acid (FA) compositions of selected lipid depot (kidney and liver) and absorption (intestine) organs in larvae and metamorphosing sea lamprey, Petromyzon marinus. Palmitic or stearic acids were generally the predominant saturated fatty acids (SFA) before and during metamorphosis, but the greatest proportion of myristic acid occurred in renal triacylglycerol (TG). Monoenes, dienes, and polyenes consist mainly of 16:1, 18:1, and 20:1, 18:2 and 20:2v6, and 18:4v3, respectively. Alterations in these predominant fatty acids occurred during lamprey metamorphosis, but depended on tissue, lipid class, and developmental status. During metamorphosis, kidney TG and phospholipid (PL) classes tended to mobilize SFA and enhance the fatty acid unsaturation, as indicated by increased unsaturatedysaturated ratio, unsaturation index (USI), and total mean chain length (MCL). There was a tendency to increase saturation in the fatty acids of liver TG and PL classes and intestine TG, FA and monoacylglycerol (MG) classes, but to increase unsaturation in the fatty acids of liver cholesteryl ester (CE), FA and MG classes and intestine PL and CE classes from larva or stage 3 to stage 7. Increased polyunsaturated fatty acids in kidney TG and PL from larvae to stage 5 transformers and intestine PL and CE from stage 3 to stage 7 transformers may reflect an osmoregulatory pre-adaptation. The presence of branched-chain SFA (BCSFA) and the odd number of fatty acids (ONFA) indicated a significant role of detritivores in the benthic larvae. Decreased abundance of BCSFA, ONFA, and 18:2 dienes occurred in the transformed intestine TG as non-trophic metamorphosis proceeded. These data suggest that sea lamprey metamorphosis may proceed in a habitat, dietary, osmoregulatory, energetic, and developmental pre-adaptation of fatty acid composition from benthic filter-feeding larvae to pelagic parasitic juveniles. ᮊ

“…In comparison with other reports of Almaco jack (Saito, 2012), our data clearly showed higher content of SFA (59.55 to 64.13 %) and MUFA (32.32 to 38.30 %) in both liver and muscle samples. Higher SFA contents found in our study, may be related to the fact that total SFAs tend to increase in fish living in warm waters, since temperature affects the fatty acids composition (Delgado, Estevez, Hortelano, & Alejandre, 1994). Moreover, Turchini et al (2003) suggested that fish can regulate and maintain certain levels of body lipid saturation by the de novo synthesis which could contribute to explain the high levels of SFA and MUFA found in the present study.…”

Almaco jack (Seriola rivoliana) is an emergent marine finfish that presents high market value. In order to study the feasibility of the exploitation of this marine resource for human consumption the evaluation of the nutritional characteristics of this species has attracted the attention of the scientific community. The lipid characteristics and fatty acid composition were evaluated in muscle, liver and gonad tissues of wild Almaco jack from Atlantic Ocean at two different maturation stages. According to results, the lipid content was found higher at pre-spawning stage (21.78 -36.17%) and highest proportion being exhibited in the liver. Palmitic acid was predominant among the saturated fatty acids (35.42 -47.80%) and oleic acid was detected as the main monounsaturated acid (25.26 -36.55%). Higher amounts of ω3 polyunsaturated fatty acids (PUFAs) were identified in gonads of resting females, of which more than 84% was accounted by docosahexaenoic acid (12.62%). Muscle and liver of resting females presented the highest ω3/ω6 ratios. The Hypocholesterolemic/Hypercholesterolemic index was higher in gonads of both maturation stages (0.97 and 1.05). The results showed that wild Almaco jack at resting stage were a better source of oleic acid and ω3 PUFAs and that liver and gonads present good nutritional by-products.

“…Cagnetta et al (1996) found similar changes in the muscle of wild gilthead sea bream, Sparus aurata , compared with farmed gilthead sea bream. Delgado et al (1994) observed, in sea bass, Dicentrarchus labrax , subjected to 8 wk of starvation, a reduction of saturated fatty acids levels as polyunsaturated ones increased, which was interpreted as a selective retention, especially in muscle cells phospholipids. De Silva et al (1997) reported a significant increase in PUFA proportion, above all DHA (22:6ω3), in tilapia, Oreochromis mossambicus × Oreochromis niloticus , subjected to a long lasting (45 d) starvation period, in both muscle and liver.…”

Dentex (mean initial weight 324 ± 5 g) from a fish farm were divided into two groups (control and fasted). At the end of experimental period (5 wk), dentex were sampled for gross muscle composition and quality analysis. For post mortem muscle analysis, after death, fish were kept in a cold chamber at 4 C, and muscle samples were taken at 4 (prerigor state), 24 (rigor state), and 82 (postrigor state) h after slaughtering. In each fish, textural and biochemical parameters were determined. During starvation, there was a drastic reduction in muscle lipid content and a relative increase of the proteolysis. There were little qualitative changes in the fatty‐acid profile of muscle lipids, although a significant increase in n3/n6 ratio in the starved dentex was detected. Starved fish also showed higher muscle firmness, but no differences in pH and water holding capacity were observed. Total and myofibrillar protein and collagen content increased significantly in starved dentex. Firmness during post mortem storage was significantly higher in starved fish, compared with control group. Preslaughtering feeding status showed decisive influence on the evolution dentex muscle quality parameters during cold storage.
