“…C18:3(n-3) and C16:3(n-3), dominating among C18 PUFA and C16 PUFA, were also recognized in this alga. Generally, the fatty acid composition found in C. racemosa is in good agreement with other results reported for Caulerpa species (Aknin et al, 1992;Khotimchenko, 1995).…”

Total lipids and fatty acid composition were monitored seasonally in exposed and sheltered Caulerpa racemosa settlements along the coast of St Juraj island (Vrsar, Croatia). The underlying sediment in the exposed area was characterized by a lower content of total lipids (0.63 AE 0.18 mg/g d.w.) and coarser grain sizes (median particle diameter [Md] ¼ 1319.5 mm) in comparison to sediment of the sheltered area (0.89 AE 0.06 mg/g d.w.; Md 378.9 mm). Despite the proximities of both populations studied, and, hence, both experiencing similar exposure to seasonal fluctuations, the algal responses were different. Total lipid changes and fatty acid composition of the related settlements indicated the differences in thallus condition during summer of 2004 and to some extent different strategies in cold adaptation during winter 2005. In August 2004, the bad condition of thalli at the sheltered site, expressed by low unsaturation (UNS/SAT 0.45), resulted from its sexual propagation state, in contrast to the advanced condition of vegetative propagation state at the exposed site (UNS/SAT 1.1). The poor thallus condition was related to its slower development at the sheltered habitat, having correspondingly lower biomass. Furthermore, at this site little or no difference in total lipids was observed with season. During the winter period (min. temp. 7.7 C) both settlements altered their fatty acid composition by increasing unsaturation (UNS/SAT up to 1.8), but a pronounced winter peak in total lipids occurred at the exposed site. Under similar environmental conditions, the C. racemosa in this study developed different strategies in cold adaptation and propagation state as a consequence of apparently varying impact of the hydrodynamism at these two proximate sites. This study suggests the mode in which exposure impacts the growth cycle of C. racemosa in temperate regions.

“…Palmitic acid and linolenic acid were the major fatty acids among all three Caulerpa species contributing to 42.98-57.07% and 10.1-27.84% of TFA, respectively. The previous studies also confirmed the dominance of C16 and C18 PUFAs and regarded this phenomenon as a characteristic feature of green algae (Aknin et al, 1992). In addition to the major fatty acids other fatty acids such as lauric (12:0), pentadecanoic acid [ ( ) T D $ F I G ] (15:0), heptadecanoic acid (17:0), 11-ecosenoic acid (20:1nÀ9), g-linolenic acid (18:3nÀ6), a-linolenic acid (18:3nÀ6) and eicosatrienoic acid (20:3nÀ3) also occurred in relative abundance.…”

“…On the other hand this improved survival rate could be attributed to the qualitative lipid composition of the fresh algae. Enteromorpha, like the other marine green algae, usually contain highly polyunsaturated C 16 and C 18 fatty acids (Akinin et al, 1992;Jones and Harwood, 1993;Khotimchenko, 1993). The supplementation of dietary unsaturated fatty acid in the diet of marine fish larvae have been reported to improve the survival rate (NRC, 1983;Dhert et al, 1991;Izquierdo, 1996).…”

A trial to incorporate dehydrated Enteromorpha in the diet of rabbitfish fry averaging 0.25 ± 0.04 g was undertaken for a period of 12 weeks. Four isonitrogenous (39% crude protein) and isoenergetic (19 kJ/g) diets were fed to fish. The dehydrated Enteromorpha was incorporated in the diets at a rate of 0 (control), 10, 20 and 30%. A fifth group of fish was fed control diet and supplemented with known weight of fresh Enteromorpha placed in plastic baskets at the bottom of the rearing tanks. The survival rate, growth performance and feed utilization efficiency were observed to decrease with increasing inclusion levels of dehydrated algae (p < 0.05). The best results of all parameters were achieved by fish fed control diet and fresh Enteromorpha (P< 0.05). Carcass protein was not affected by the different treatments while lipid content was observed to increase in the group of fish supplemented with fresh Enteromorpha (P< 0.05). It is concluded that further studies are needed on the dehydration techniques of Enteromorpha as well as on the digestibility and assimilation of diets containing dehydrated algae.
