Copper (Cu) is an essential element for various vital biological processes, but a comprehensive systematic review focusing on Cu metabolism, deposition, nutritional functions, and toxicity in fish is lacking. We found dietary Cu requirements for fish are 2–22.6 mg/kg, but information for some economically important species is lacking. Waterborne Cu can influence the absorption of dietborne Cu, emphasizing

Influence of geographical origin and shell positions on nacre color and thickness in mabé pearl oysters Pteria penguin Aquaculture (IF 4.5) Pub Date : 2024-03-26 Tracy Aisea, Gunawan Muhammad, Asep Sahidin, Akira Komaru
To examine variations in nacre color and thickness in oysters obtained from Tonga and Japan, a novel approach with a focus on their potential for mabé pearl production was used. Detailed analyses of color and microstructure revealed that the middle position of the right-valve nacre (position 1) primarily showed a reduction in yellow pigmentation. This was indicated by a decrease in the yellowness index

Influence of salinity on rainbow trout (Oncorhynchus mykiss) smolt development and postsmolt performance Aquaculture (IF 4.5) Pub Date : 2024-03-26 Enrique Pino-Martinez, Pablo Balseiro, Håkon F. Kvittingen, Cindy Pedrosa, Marnix Gorissen, Sigurd O. Handeland
Rainbow trout aquaculture has large potential for growth, but requires better understanding of aspects like smoltification and its effect on trout performance after seawater transfer. The present study examined the effect of three different salinities (fresh water, 3–5 ‰ and 15–16 ‰) on smoltification and growth of rainbow trout (70 ± 10 g) reared under constant light between March–June 2018; it also

Assessment of patho-physiological responses, gill histopathology and SEM analysis in common carp (Cyprinus carpio) exposed to varied doses of chloramine-T: A potent chemotherapeutic agent Aquaculture (IF 4.5) Pub Date : 2024-03-26 Rizwan Ahmad Dar, Syed Shariq Nazir Qadiri, Feroz Ahmad Shah, Shabir Ahmad Dar, Nazia Ahad, Asifa Wali, Ashwani Kumar, Mansoor Ahmad Rather, Bilal Ahmad Bhat
Chloramine-T (Cl-T) is a chemo-therapeutant used at aquafarms to control fish mortalities associated with bacterial and parasitic infections in freshwater aquaculture. It is also effective as a disinfectant against a wide range of viruses known to cause disease in fish. However, a very little information is available on the patho-physiological alterations in common carp () exposed to different doses

Reassembly and biotic sources of carapace bacterial community of Portunus trituberculatus after host molting Aquaculture (IF 4.5) Pub Date : 2024-03-26 Weichuan Lin, Jiameng Chen, Ce Shi, Changkao Mu, Chunlin Wang, Yangfang Ye
Crustaceans molt repeatedly during their development, which leads to frequent reassembly of their associated microbial communities. However, the reassembly of the carapace bacterial community (CBC) and its sources remain largely unclear. Here, these concerns were explored by investigating the succession pattern, assembly processes, and biotic sources of CBC of the swimming crab after host molting.

Determination of optimal temperature, salinity, and stocking density combinations for larval growth and survival of diploid, triploid, and tetraploid Fujian oyster (Crassostrea angulata) Aquaculture (IF 4.5) Pub Date : 2024-03-26 Yuanxin Liang, Xianchao Bai, Chengxun Xu, Qi Li
For nurseries, thriving larvae mean higher incomes. Three factors - temperature, salinity and stocking density - are critical to the success of larval rearing. However, the effects of these three factors on the performance of diploid, triploid and tetraploid larvae have not yet been comprehensively investigated. In this study, the combined effects of temperature (T, 12.0–35.0 °C), salinity (S, 10.0–38

Climatic events and disease occurrence in intensive Litopenaeus vannamei shrimp farming in the Mekong area of Vietnam Aquaculture (IF 4.5) Pub Date : 2024-03-26 Ngan Thi Thanh Le, Claire W. Armstrong, Eivind Hestvik Brækkan, Arne Eide
As recurrent disease outbreaks impart economic adversity across the global shrimp farming sector in general, and in Asia in particular, clarifying determinants of outbreak susceptibility carries significance for sustainability in economic growth and social and environmental prospects. This study employs logistic regression to assess the probability of disease occurrence in intensive white leg shrimp
