Taurine supplements in high-fat diets improve survival of juvenile Monopterus albus by reducing lipid deposition and intestinal damage

Yong Shi, Lei Zhong, Huan Zhong, Junzhi Zhang, Changbao Che, Guihong Fu, Yi Hu, Kangsen Mai

Summary: The study found that a high-fat diet had negative effects on growth performance, lipid deposition, antioxidant ability, and intestinal health in rice field eels. However, supplementation with 0.2% or 0.5% taurine improved growth performance, reduced lipid deposition, enhanced antioxidant ability, and maintained intestinal health. The best growth performance was observed in fish supplemented with 0.5% taurine.

Environmental consequences of using insect meal as an ingredient in aquafeeds: A systematic view

Hung Quang Tran, Hien Van Doan, Vlastimil Stejskal

Summary: Various studies have shown that using insect meal in aquaculture can reduce land use, but it also leads to greater energy consumption and larger carbon footprint compared to traditional protein sources. Substituting different types of insect meals in aquatic diets can significantly impact solid waste production, with a reduction in marine forage fish required per unit fish yield. Therefore, there is a trade-off when considering the environmental consequences of using insect meal as an aquafeed ingredient.

Cinner, Tim R. McClanahan, Edward H. Allison, Whitney R. Friedman, Claudio Silva, Eleuterio Yanez, Maria A. Barbieri, Kristin M. Kleisner

Summary: This study develops a comprehensive resilience framework to examine fishery systems across ecological, socio-economic, and governance dimensions, distilling and defining 38 attributes that confer climate resilience. The directionality and mechanism of these attributes depend on specific context, capacities, and scale, with evidence of interdependencies among them. However, meaningful quantification of the attributes' contributions to resilience in fisheries remains a challenge, as most studies focus on the ecological dimension.

Farming the Ocean - Seaweeds as a Quick Fix for the Climate?

M. Troell, P. J. G. Henriksson, A. H. Buschmann, T. Chopin, S. Quahe

Summary: Seaweed farming has been promoted as a climate solution, but the carbon sink function is diminished due to consumption and alternative applications. Seaweeds can reduce greenhouse gas emissions through carbon offset and potentially through reducing enteric methane emissions from ruminants and bioenergy production. However, further research is needed to understand seaweeds' carbon cycling and contributions.

Effects of herbal extracts (Foeniculum vulgare and Artemisia annua) on growth, liver antioxidant capacity, intestinal morphology and microorganism of juvenile largemouth bass, Micropterus salmoides

Guanglun He, Hao Sun, Ruisheng Liao, Yexin Wei, Tingting Zhang, Yongjun Chen, Shimei Lin

Summary: This study investigated the effects of Foeniculum vulgare extract (FE) and Artemisia annua extract (AE), either alone or combined, on the growth, liver antioxidant capacity and intestinal flora immunity of Micropterus salmoides. The results showed that diets supplemented with AE or a combination of FE and AE significantly enhanced the growth and feed intake of largemouth bass. Furthermore, the use of these medicinal herb extracts increased antioxidant enzyme activities and decreased oxidative damage in the liver. AE also affected the intestinal bacterial structure, increasing beneficial bacteria and reducing potentially pathogenic bacteria.

Summary: The study found that adaptation measures currently focus more on enhancing ecological resilience rather than social resilience in the context of climate change, indicating a greater emphasis on management adaptation. In addition, social adaptation measures are more responsive and used outside the context of climate change, with a lack of centralized planning and organization in the implementation of stakeholder adaptations.

Summary: This study evaluated the feasibility of using methanotroph bacteria meal as a fishmeal substitute in largemouth bass diets. The results showed that an inclusion level of 129 g/kg of the bacteria meal did not significantly affect the growth performance of the fish. However, higher inclusion levels negatively affected intestinal morphology and inflammatory cytokine gene expression.
