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
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
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

Status of a commercial sea scallop enhancement project in Iles-de-la-Madeleine (Quebec, Canada)
Springer Science and Business Media LLC - Tập 5 - Trang 259-266 - 1997
G. Cliche, S. Vigneau, M. Giguere
The main objective of the REPERE (REcherche sur le Petoncle a des fins d'Elevage et de REpeuplement) research programme, initiated in the Iles-de-la-Madeleine in 1991, was to enhance natural sea scallop (Placopecten magellanicus) populations which were greatly reduced by overfishing. Sea bed seeding was chosen as the best approach to achieve this goal. In 1992, after two years of scientific resear...... hiện toàn bộ
Diet and fish choice of Eurasian otters (Lutra lutra L.) in fish wintering ponds in Hungary
Springer Science and Business Media LLC - Tập 15 - Trang 393-402 - 2007
József Lanszki, Zsuzsanna S. Pallos, Dénes Nagy, Grace Yoxon
The diet composition and fish preference of piscivorous Eurasian otters (Lutra lutra) were studied in two fish farm systems in Hungary using spraint (otter faeces) analysis during two wintering periods. The primary food source of otters in both fish farms was fish (97–99% of biomass). The main fish prey was small-sized, below 100 g in weight (96% in both areas), while fish prey above 500 g compris...... hiện toàn bộ
Integrated system for bioremediation of Nile tilapia rearing effluent and astaxanthin production by Haematococcus pluvialis
Springer Science and Business Media LLC - - 2024
Laenne Barbara S. de Moraes, Géssica Cavalcanti P. Mota, Bruna A. Bernardino da Silva, Carlos Yure B. Oliveira, Juliana Ferreira dos Santos, Alfredo Olivera Gálvez, Ranilson de Souza Bezerra
Haematococcus pluvialis is a microalga that can reduce the levels of inorganic and organic components in effluents, in addition to production of the high-value carotenoid astaxanthin. The present study proposed an integrated system for the simultaneous treatment of effluent from a Nile tilapia recirculation system and astaxanthin production using the microalga H. pluvialis. Cultures were developed...... hiện toàn bộ
