The evolutionary ecology of fatty‐acid variation: Implications for consumer adaptation and diversification

et al. 2021

The nutritional diversity of resources can affect the adaptive evolution of consumer metabolism and consumer diversification. The omega‐3 long‐chain polyunsaturated fatty acids eicosapentaenoic acid (EPA; 20:5n‐3) and docosahexaenoic acid (DHA; 22:6n‐3) have a high potential to affect consumer fitness, through their widespread effects on reproduction, growth and survival. However, few studies consider the evolution of fatty acid metabolism within an ecological context. In this review, we first document the extensive diversity in both primary producer and consumer fatty acid distributions amongst major ecosystems, between habitats and amongst species within habitats. We highlight some of the key nutritional contrasts that can shape behavioural and/or metabolic adaptation in consumers, discussing how consumers can evolve in response to the spatial, seasonal and community‐level variation of resource quality. We propose a hierarchical trait‐based approach for studying the evolution of consumers’ metabolic networks and review the evolutionary genetic mechanisms underpinning consumer adaptation to EPA and DHA distributions. In doing so, we consider how the metabolic traits of consumers are hierarchically structured, from cell membrane function to maternal investment, and have strongly environment‐dependent expression. Finally, we conclude with an outlook on how studying the metabolic adaptation of consumers within the context of nutritional landscapes can open up new opportunities for understanding evolutionary diversification.

“…Previous studies on Murray cod (Maccullochella peelii peelii) and seahorse (Hippocampus abdominalis) larvae found that Algamac 3050 performed best in terms of growth performance among several Artemia enrichment products (Woods 2003;Francis et al 2019), which is consistent with our study. However, meagre (Argyrosomus regius) and sterlet (Acipenser ruthenus) larvae showed higher growth performance when fed Red Pepper enriched Artemia (Campoverde and Estevez 2017;Lundova et al 2018).…”

The present study was planned to determine an optimum live-feeding protocol for angelfish larvae (Pterophyllum scalare). Larvae with an initial weight of 0.10 mg, a length of 4.5 mm, and a depth of 1 mm were reared on three different feeding regimens for 30 days. All experimental larval groups were fed Artemia nauplii from the end of the yolk-sac resorption. The control treatment (Group I) was maintained on Artemia nauplii on days 14-28, and on Artemia nauplii + dry feed on days 29 and 30. Group II was reared with Artemia nauplii enriched with Algamac 3050 on days 14-28 and with dry feed + Artemia nauplii enriched with Algamac 3050 on days 29 and 30, whereas Group III was fed with Artemia nauplii enriched with Red Pepper on days 14-28, and with dry food + Artemia nauplii enriched with Red Pepper on days 29 and 30. The highest weight (37.8±0.51 mg) and length (15.8±0.35 mm) were determined in Group II with significant differences from the control group (p<0.05). However, enrichment treatments were comparable in terms of growth performance (p>0.05). The survival rate of the larvae in the treatments varied between 70-75% without significant differences (p>0.05). Overall, the study results suggest that a feeding protocol for angelfish larvae with the administration of Artemia nauplii during the first two weeks after hatching and then enriched Artemia with Algamac 3050 over the following 14-28 days followed by a gradual weaning onto dry feed.

“…Neither the growth nor survival was impaired in the current research and therefore the use of the higher density to increase fish biomass gain seems justified. Several studies on different factors are available in sterlet larvae, in which stocking densities commonly used are between 2.5 and 17 sterlet larvae L −1 (Feledi & Rónyai, 2013; Laczynska et al, 2020; Lundova et al, 2018; Rybnikár et al, 2011). According to Chebanov and Galich (2011) norm for endogenous feeding phase stocking density is 7000 larvae per m 2 , while the data for already feeding larvae are not provided.…”

“…Chosen densities were 5, 10, and 20 larvae per litre which imply 1250, 2500, and 5000 randomly placed larvae per rearing units in low (L), medium (M), and high (H) density groups, respectively. These densities were selected based on studies published on sterlet larvae (Feledi & Rónyai, 2013;Laczynska et al, 2020;Lundova et al, 2018;Rybnikár et al, 2011).…”

The effect of stocking density on sterlet Acipenser ruthenus (Linnaeus, 1758) larvae in the recirculating aquaculture system

et al. 2022

The sterlet (Acipenser ruthenus) is a widely cultured sturgeon species due to its small body size, its relatively low rearing costs, early sexual maturation, and remarkable growth in the first 2 years (Prokeš et al., 2011).The success of sterlet culture fundamentally depends on the application of appropriate larval rearing protocol (Wegner et al., 2009). Difficulties like high mortality, low growth rate, occasions of cannibalism, overfeeding, bacterial infections, and weaning difficulties are regularly present during the larval period in sturgeons (Gisbert & Williot, 2002;Laczynska et al., 2020;Williot et al., 2018). These obstacles are associated with inadequate nutrition and/or unsuitable technological settings (Agh
