Artificial fertilization and generating families for a selective breeding programme of large yellow croaker (Larimichthys crocea)
International Aquatic Research - Tập 9 - Trang 161-167 - 2017
Xinxiu Yu, Changwen Wu, Hans Magnus Gjøen
Large yellow croaker is an important marine aquaculture species in China. The aim was to determine an appropriate protocol of artificial fertilization for family construction in the breeding programme based on two trials. In trial 1, luteinizing hormone-releasing hormone A3 (LHRHA3) was injected once, with a dosage of 2 μg/kg for females and 1 μg/kg for males. The latency time was in the range of ...... hiện toàn bộ
An overview of Cladoceran studies conducted in mine water impacted lakes
International Aquatic Research - Tập 10 - Trang 207-221 - 2018
Jaakko Johannes Leppänen
Mine-fed waters have been rigorously studied, but most of the ecological research on mine water has been conducted in riverine systems. Lakes, however, are known to recover from pollution more slowly than riverine systems and, thus, the impacts of mine water on lakes are equally interesting. One of the most important biological components in lakes are the Cladocera, an order of crustacean zooplank...... hiện toàn bộ
Development of a system for measuring calcitonin in the stingray Dasyatis akajei (a cartilaginous fish): the possible involvement of stingray calcitonin in gonadal development
International Aquatic Research - Tập 11 - Trang 267-276 - 2019
Takashi Takagi, Toshio Sekiguchi, Yuichi Sasayama, Atsuhiko Hattori, Takushi X. Watanabe, Yoichiro Kitani, Yoshiaki Tabuchi, Hajime Matsubara, Ajai K. Srivastav, Tran Ngoc Hai, Thumronk Amornsakun, Nobuo Suzuki
To elucidate the physiological role of calcitonin (CT) in stingrays (cartilaginous fish), an enzyme-linked immunosorbent assay (ELISA) system using a specific antibody against stingray CT has been developed. Synthetic stingray CT was subcutaneously injected into mice four times—once every 2 weeks—together with an adjuvant. We purified the IgG antibody fraction using the protein A affinity chromato...... hiện toàn bộ
Thermal preference, tolerance, and thermal aerobic scope in clownfish Amphiprion ocellaris (Cuvier, 1830) predict its aquaculture potential across tropical regions
International Aquatic Research - Tập 11 - Trang 187-197 - 2019
Gabriela Velasco-Blanco, Ana Denise Re, Fernando Díaz, Leonardo Ibarra-Castro, Maria Isabel Abdo-de la Parra, Luz Estela Rodríguez-Ibarra, Carlos Rosas
The clownfish Amphiprion ocellaris is widely distributed in the coral reef ecosystems of tropical and subtropical regions of the West Indo Pacific, an area that hosts economically valuable species, and, thus, a suitable candidate for warm water aquaculture. This study determined the preferred temperature, critical threshold limits, represented by critical thermal maximum and critical thermal minim...... hiện toàn bộ
Characterization of Vibrio parahaemolyticus isolated from farmed sea bass (Dicentrarchus labrax) during disease outbreaks
International Aquatic Research - Tập 5 - Trang 1-11 - 2013
Sadok Khouadja, Faouzi Lamari, Amina Bakhrouf
Vibrio parahaemolyticus was isolated from the internal organs of diseased sea bass (Dicentrarchus labrax) cultured in a marine cage farm and an inshore fish farm in the summer 2010. All strains isolated from diseased sea bass were tested for virulence by intraperitoneal injection. The isolates (n = 6) were pathogenic for sea bass. Only bacterial strains showing haemolytic activity were virulent. L...... hiện toàn bộ
Outbreak of growth anomalies in coral communities of Qeshm Island, Persian Gulf
International Aquatic Research - Tập 7 - Trang 151-156 - 2015
Pavriz Tavakoli-Kolour, Javid Kavousi, Hamid Rezai
Reports on the outbreaks of coral diseases are on the rise, stating that diseases are considered to be one of the main drives in the decline of global coral reefs. In this study, the outbreak of growth anomalies (GAs) in coral communities of the south of Qeshm Island in the Persian Gulf is reported. Despite a previous report on the localized GAs on a few colonies, this is the first report of GA ou...... hiện toàn bộ

Hemolymph osmotic, ionic status, and branchial Na+/K+-ATPase activity under varying environmental conditions in the intertidal grapsid crab, Gaetice depressusd
International Aquatic Research - Tập 4 Số 1 - 2012
Takeshi Nanba, Hideya Takahashi, Tsukasa Abe, Waichirou Godo, Maho Ogoshi, Hirotaka Sakamoto, Naoaki Tsutsui, Tatsuya Sakamoto
Abstract Osmo- and ionoregulatory abilities were examined in the intertidal grapsid crab, Gaetice depressus, transferred from normal seawater (30 ppt) to low (10 ppt) or high (50 ppt) salinities for 2 and 10 days, in addition to animals kept out of water for 2 days. The results of the hemolymph osmotic and ionic status indicate ...... hiện toàn bộ
Effects of dietary fishmeal substitution with corn gluten meal and poultry meal on growth rate and flesh characteristics of Chinook salmon (Oncorhynchus tshawytscha)
International Aquatic Research - Tập 11 Số 4 - Trang 325-334 - 2019
Katarina H. Doughty, Shawn R. Garner, Mark A. Bernards, John Heath, Bryan D. Neff
Abstract There is considerable interest in developing diets that maintain growth performance and market appeal for salmon aquaculture while relying less on fishmeal as a major ingredient. Here, we compared growth rate, survival, fat content, tissue colouration and carotenoid levels (astaxanthin) in Chinook salmon (Oncorhynchus tshawytscha...... hiện toàn bộ
Growth performance, feed utilisation and biological indices of Tra catfish (Pangasianodon hypophthalmus) cultured in net cages in pond fed diets based on locally available feed resources
International Aquatic Research - Tập 8 - Trang 309-321 - 2016
Chau Thi Da, Torbjörn Lundh, Jan Erik Lindberg, Håkan Berg
The feeding experiment was conducted to evaluate the efficacy of locally available feed resources for Tra catfish (Pangasianodon hypophthalmus) cultured a series of 21 hapa net cages installed in the earthen pond during a 4-month period. The reference diet contained fish meal as the main crude protein (CP) source, whilst in the seven test diets 20–100 % of the fish meal CP was replaced with CP fro...... hiện toàn bộ
