Study of the requirements of dietary cholesterol at two different growth stages of Pacific white shrimps, Litopenaeus vannamei
Springer Science and Business Media LLC - - 2019
Wei Zhang, Qihui Yang, Beiping Tan, Fengmei Wang, Xiaohui Dong, Shuyan Chi, Hongyu Liu, Shuang Zhang, Hualang Wang
Two 8-week feeding experiments were conducted to investigate the cholesterol requirements of Litopenaeus vannamei at two different growth stages—with initial body weights of 0.61 ± 0.00 g (juvenile) and 4.25 ± 0.00 g (subadult). Six diets containing cholesterol (C) 0.03% (FM-fish meal), 0.09% (0.05% C), 0.14% (0.1% C), 0.27% (0.2% C), 0.47% (0.4% C), and 0.90% (0.8% C) were prepared with red fish ...... hiện toàn bộ
Amino acids composition and protein quality evaluation of marine species and meals for feed formulations in cephalopods
Springer Science and Business Media LLC - - 2012
Jesús Cerezo Valverde, Silvia Martínez-Llorens, Ana Tomás Vidal, Miguel Jover, Carmen Rodríguez, Juán Estefanell, Joan I. Gairín, Pedro Miguel Domingues, Carlos J. Rodríguez, Benjamín García García
The amino acid composition and protein levels of three species of cephalopods (Octopus vulgaris, Loligo gahi and Todarodes sagittatus), the natural diets of common octopus (O. vulgaris) and different kinds of meals were determined in order to optimise the content of these nutrients in artificial feeds. Arginine, leucine and lysine were the most abundant essential amino acids in cephalopods, while ...... hiện toàn bộ
Enhanced disease resistance in the Indian snakehead, Channa punctata against Aeromonas hydrophila, through 5 % feed supplementation with F. benghalensis (aerial root) and L. leucocephala (pod seed)
Springer Science and Business Media LLC - Tập 23 - Trang 1127-1140 - 2014
Vipin Kumar Verma, Kumari Vandana Rani, Neeta Sehgal, Om Prakash
Ficus benghalensis and Leucaena leucocephala are perennial trees commonly known for their wide medicinal use in India. Immuno-stimulatory effect of F. benghalensis (aerial root) or L. leucocephala (pod seeds) 5 % powder as supplementary ingredients in the artificial fish feed of Indian spotted snakehead, Channa punctata, was compared with control group (fish fed with non-s...... hiện toàn bộ

Tự ngộ độc amoniac ở cá chép thường: Các nghiên cứu trường hợp Dịch bởi AI
Springer Science and Business Media LLC - Tập 15 - Trang 277-286 - 2007
Zdeňka Svobodová, Jana Máchová, Hana Kroupová, Miriam Smutná, Ladislav Groch
Ba nghiên cứu trường hợp về hiện tượng tự ngộ độc amoniac ở cá chép thường (Cyprinus carpio L.) được mô tả. Trong trường hợp đầu tiên, cá chép năm tuổi với hệ tiêu hóa đầy đủ được chuyển từ nước ao (22°C) sang nước máy (17°C) trong thời gian phát triển. Trong trường hợp thứ hai, cá chép có thể thương phẩm được chuyển từ vùng đánh bắt trong ao (18°C) sang ao chứa (10–12°C). Việc thu hoạch được thực...... hiện toàn bộ

Could a seasonal-like reduction in light radiation intensity affect cultured shrimp (Penaeus stylirostris stimpson) yield?
Springer Science and Business Media LLC - Tập 10 - Trang 43-55 - 2002
P. Garen, J.-L.M. Martin
Experiments were carried out to establish the effect of a simulateddecrease in daylight intensity on the yield of the cultured shrimpPenaeus stylirostris. The purpose of these experiments wasto simulate the periods in intertropical regions, which may last for severaldays, when solar radiation levels fall due to seasonal cloud cover. After 4weeks of culture, the light reduction resulted in lower sh...... hiện toàn bộ
The effect of darkness on mating and pleopodal egg production time in a freshwater crayfish, Astacus leptodactylus Eschscholtz
Springer Science and Business Media LLC - Tập 18 - Trang 843-849 - 2009
Muzaffer Mustafa Harlioğlu, Tuba Çakmak Duran
In the present study, the effect of darkness on the timing of mating and pleopodal egg production in Astacus leptodactylus was investigated. Crayfish were exposed to three different light regimes: natural day light regime (control, mean 10.04-h light/13.96-h dark); 24-h dark (24 h D); 8-h light/16-h dark (8 L:16 D). Experiments were carried out between November 2006 and January 2007 with 36 males ...... hiện toàn bộ
Counting, locating, and sizing of shrimp larvae based on density map regression
Springer Science and Business Media LLC - - 2023
Chao Zhou, Guowei Yang, Lihui Sun, Shifa Wang, Weipeng Song, Jianlin Guo
The count, location, and size of shrimp larvae are important observations for their intensive breeding, which could evaluate the culture density, growth, and yield. Recent works on the counting of dense aquatic objects in an image are mainly accomplished by the density map regression based on convolutional neural network (CNN). These regression methods only give the estimated density map and the c...... hiện toàn bộ
Pathogenicity of Edwardsiella tarda in Oreochromis mossambicus and treatment by Tamarindus indica seed extract
Springer Science and Business Media LLC - Tập 29 - Trang 1829-1841 - 2021
Mrinal Seth, Natrajan Chandrasekaran, Amitava Mukherjee, John Thomas
The occurrence of fish diseases contributes to massive economic loss to the aquaculture industry. Edwardsiella tarda, a known pathogenic organism in Oreochromis mossambicus, infects several freshwater fishes. The present study attempts to find an effective treatment against E. tarda infection using natural plant-based bioproducts. Tamarindus indica seed extract was used to study its antibacterial ...... hiện toàn bộ
Compound Chinese herbal extract (RMCP) supplementation improves defense against Aeromonas veronii infection in Chinese mitten crab Eriocheir sinensis
Springer Science and Business Media LLC - Tập 31 - Trang 2281-2295 - 2023
Huihua Zhou, Chunlei Gai, Jie Liu, La Xu, Haipeng Cao, Jian An
Chinese herbal medicinal preparations are considered promising immunoprophylactic agents in aquaculture. Yet the protection of Chinese mitten crabs Eriocheir sinensis against Aeromonas veronii infection using Chinese herbal medicinal preparations is still unknown. In this study, a 45-day feeding trial was carried out to examine the defense ability against A. veronii infection in E. sinensis fed di...... hiện toàn bộ
