Reviews in Aquaculture, Год журнала: 2022, Номер 15(3), С. 1028 - 1057

Опубликована: Окт. 3, 2022

Abstract Aquaculture has been one of the fastest‐growing food production systems sectors for over three decades. With its growth, demand alternative, cheaper and high‐quality feed ingredients is also increasing. Innovation investments on providing new functional alternatives have yielded several viable alternative raw materials. Considering all current ingredients, their circular adaption in aquafeed manufacturing industry clearly utmost importance to achieve sustainable aquaculture near future. The use terrestrial plant materials animal by‐products predominantly used puts a heavily reliance agroecosystems, which own sustainability concerns. Therefore, needs progress with that must be more resilient consistent, considering perspective. In this review, we assess trends using various marine organisms, ranging from microorganisms (including fungi, thraustochytrids, microalgae bacteria) macroalgae macroinvertebrates as biological resources. This review focuses trend resources development value chains. this, present perspective promoting novel economy chains promote re‐use valuable ingredients. Thus, highlight some potentially important marine‐derived deserve further investigations improving or addressing aquaculture.

Abstract A meta‐analysis of literature data on essential amino acid (EAA) requirements fish and crustaceans was performed to re‐estimate EAA provide ideal profiles. Large numbers studies have been conducted over the past decades. However, estimated different species showed a large variation due differences in methodological approaches regression models. An extensive search inclusion were following Preferred Reporting Items for Systematic Reviews Meta‐Analyses guidelines this study, resulting dataset 358 covering 77 species. The relative percentage maximum weight gain used as outcome evaluate 10 requirements. Forest plots analysis employed heterogeneity analysis, study allocation re‐estimation Results that trophic level, water temperature dietary levels affected estimation. suggested (expressed % crude protein, CP) were: arginine (Arg) 5.0 (±0.14), histidine (His) 2.0 (±0.11), isoleucine (Ile) 3.3 (±0.16), leucine (Leu) 4.9 (±0.24), valine (Val) 3.8 lysine (Lys) 5.2 (±0.12), sulfur acids (Met + Cys) 3.5 (±0.18), total aromatic (Phe Tyr) 6.2 threonine (Thr) (±0.18) tryptophan (Trp) 0.9 (±0.08).

Low-fishmeal and protein-saving diets are two prominent nutritional strategies utilized to address challenges related the scarcity sustainability of protein sources in aquaculture. However, these have been associated with adverse effects on growth performance, feed utilization, disease resistance aquatic animals. To mitigate challenges, exogenous protease has applied enhance quality lower contents or fishmeal alternatives, thereby improving bioavailability ingredients. Additionally, preparations were also used enzymatically hydrolyze thus enhancing their utilization. The present review aims consolidate recent research progress use aquaculture conclude benefits limitations its application, providing a comprehensive understanding subject identifying opportunities for future research.

Опубликована: Март 7, 2023

Cottonseed protein concentrate is a sustainable fishmeal alternative in aquafeed. A 10-week experiment was conducted to investigate the effects of cottonseed concentrate-based diet with and without multi-strain yeast fractions (MsYF) on growth, bile acid metabolism, health largemouth bass. Four hundred fish (54.0 ± 0.0 g) were casually distributed into 16 tanks (4 replicates/diet). Fish fed 4 iso-nitrogen iso-energetic diets 3 times daily, including (FM), soy (SPC; replacing 81% protein), (CPC; CPC supplemented 800 mg/kg MsYF (CPCY). Results showed that survival SPC lowest, i.e., 48%, no apparent effect among other treatments; we omitted additional analyses. lower growth than FM (P < 0.05). highest nuclear dense hepatic phenotypes ratio (50%), followed by CPCY (33%) (17%). Further, dietary increased total cholesterol triglyceride levels concurrently synthesis but decreased synthesis-associated transcription Furthermore, transport-associated 0.05), then induced an increment plasma cholic chenodeoxycholic content decrement genus Romboustia Regarding MsYF, reduced lipid accumulation 0.05) compared CPC, suggesting improvement liver health.

Towards a low-carbon footprint: Current status and prospects for aquaculture

Water Biology and Security, Год журнала: 2024, Номер 3(4), С. 100290 - 100290

Опубликована: Июль 27, 2024

Aquaculture is one of the fastest-growing agricultural sectors globally and becoming increasingly important for producing sustainable healthy diets with relatively low climate impacts. In comparison to livestock production, especially beef, seafood production has lower carbon emissions. Additionally, some species can extract from aquatic environments, contributing an extended cycle. However, potential negative environmental consequences in aquaculture might increase growing global population demand food. Herein, we review effects different products on greenhouse gas (GHG) We also summarize approaches improving footprints mitigating change. Key elements, including feed efficiency, selecting suitable farmed species, implementing farming practices management aquaculture, are discussed, as well trade-offs between capture fisheries. Crucially, performance gaps among underscore consumer-oriented advice significantly reduce uncertainties knowledge related sequestration GHG emissions ponds necessitate further research. Overall, holistic evaluation strategic intervention regarding fundamental essential achieving a sustainable, low-carbon future aquaculture.

A 10-week growth study was conducted to evaluate the effect of a natural gas fermentation bacterial meal (FeedKind®, FK) as fishmeal (FM) alternative in largemouth bass (Micropterus salmoides) (48.0 ± 0.03 g). Four isonitrogenous and isoenergetic diets were formulated including one commercial control (C, 42% FM) three experimental with gradient FK 3% (FK3, 29%FM), 6% (FK6, 26%FM) 9% (FK9, 23%FM), respectively. FK-fed groups showed significantly higher SR than that C group. The WGR SGR fish fed FK3 FK6 those FK9, but not statistical different from apparent digestibility coefficients dry matter nutrients. Further, increased ratio SOD/MDA plasma liver, upregulation intestinal Keap1 downregulation HIF1α found FK3. Furthermore, microbial richness diversity.

Agouti-related protein (AgRP) is a neuropeptide synthesized by AgRP/NPY neurons and transcribed as 132 amino acids in humans 142 (AgRP1) Japanese seabass ( Lateolabrax maculatus ) fish. AgRP are activated hormonal signals of energy deficits inhibited surpluses have been demonstrated to the ability sense dynamics blood glucose concentrations “glucose sensor” mammals. It widely recognized that an endogenous antagonist melanocortin-3 -4 receptors (MC3R MC4R) hypothalamus, exhibiting potent orexigenic activity control homeostasis. Most fish, especially carnivorous cannot make efficient use carbohydrates. When carbohydrates like corn or wheat bran added sources, they often cause feeding inhibition metabolic diseases. fishmeal replaced plant protein, this does not completely eliminate carbs, limiting utilization proteins aquaculture. Our previous study showed AgRP, Y (NPY) principal molecule correlates well with behavior from anorexia adaptation. The Ghrelin/Leptin-mTOR-S6K1-NPY/AgRP/POMC feed intake regulatory pathway responds plant-oriented which contains glucose. However, its function mechanism still clear.
