“…However, the increased culture density, the international trading of fish stocks and the lack of approved drugs have increased the impact of parasitic diseases (Sitjà-Bobadilla, 2009;Rigos and Katharios, 2010). Enteromyxum leei is a myxosporean enteric parasite seriously affecting Mediterranean sparid cultures (Palenzuela, 2006;Sitjà-Bobadilla and Palenzuela, 2011).…”

“…The impact of the disease is not limited to direct mortality, but also to weight loss, poor conversion efficiency, delayed growth and reduced marketability (Golomazou et al, 2004;Palenzuela, 2006;Rigos and Katharios, 2010). In addition no prophylactic or palliative treatments are available.…”

“…In recent years, epitheliocystis disease outbreaks have increased due to the introduction of new species and to the expansion of aquaculture. At present, it is considered a serious disease with a major potential impact on aquaculture production systems (Rigos & Pantelis 2010). Epitheliocystis has been described as early as 7 dph in cultured sharpsnout sea bream larvae (Katharios et al 2008), with mortalities reaching 100% at 25 dph, and Venizelos & Benetti (1996) described epitheliocystis disease at the metamor phosis stage (28 to 42 dph) of the Pacific yellowtail Seriola mazatlana.…”

Aquaculture of cobia has gained popularity in the last decade, and this species is now farmed in several countries in Latin America and Asia. Despite recent improvement in production techniques that allowed the expansion of the industry, little is known about the diseases that affect cobia during the larviculture stage. In this article we investigated the cause of mass mortalities occurring 13−20 d post-hatching in 3 cycles of cobia larviculture. Wet mounts from diseased larvae gills revealed the presence of cyst-like basophilic inclusions. DNA from the cysts was extracted and PCR amplified using the 16S rRNA gene universal primers for prokaryotes. The amplified products were sequenced and analyzed using BLAST, finding a similarity of 99% with Endozoicomonas elysicola, a Gram-negative bacterium. Confirmation of E. elysicola was conducted by designing a specific probe for in situ hybridization. Specific primers were also designed for diagnostic purposes. This is the first report of epitheliocystis in cobia larvae and also the first report of E. elysicola as an epitheliocystis-causing agent.

Wet-mount analysis and histopathology of gills from diseased fish showed characteristic lesions of epitheliocystis. In this article we present the first description of epitheliocystis causing severe mortalities in cobia larvae. MATERIALS AND METHODS AnimalsCobia larvae were produced and reared at CENI-ACUA's laboratory in Punta Canoas Bolivar, Colombia. Mature breeders were held in captivity at CEINER (Center for Research, Education and Recreation) and fertilized eggs were shipped to CENI-ACUA. Larviculture was performed in circular larval rearing tanks (6−7 t) under flow-through production according to published protocols (Benetti et al. 2008). BackgroundDuring cobia larviculture at CENIACUA, 3 independent cycles presented with sudden events of mortality starting at 13 to 22 dph. The first signs were detected in Outbreak A at 13 dph, in Outbreak B at 22 dph and in Outbreak C at 15 dph. Mortalities started 12 h after the initial symptoms appeared, reaching almost 100% by 7 d. After the first outbreak, screening was initiated on 9 dph animals by wet mount and histopathology of gill tissue in order to detect early pathological signs of the disease. HistologyMoribund larvae from the 3 outbreaks were anesthetized using clove oil and necropsied. Whole larvae were fixed in neutral 10% buffered formalin for 24−48 h, embedded in paraffin, sectioned and stained with hematoxylin and eosin as described by Faulk et al. (2007). Selected sections were also analyzed by Gram-Twort staining (Ollett 1951). Each larva was examined, and the severity of the disease was determined with a grading system based on...

The aim of this review is to provide an update of Seriola spp. farming in the world, excluding yellowtail (S. quinqueradiata), and to identify strengths and weaknesses of these species as candidates for aquaculture diversification in different areas of the world. Farmed Seriola species other than yellowtail are yellowtail kingfish (S. lalandi) in Japan and Australia, longfin yellowtail (S. rivoliana) in the United States, greater amberjack (S. dumerili) in Japan, the Mediterranean and more recently Vietnam, and Pacific yellowtail (S. mazatlana) in North and Central America. Candidate countries for Seriola spp. farming development are China (although there are no published production statistics to date), New Zealand and the Canary Islands. The main bottlenecks for further expansion of Seriola spp. farming appear to be disease impact, lack of genetic improvement programs and incomplete knowledge of nutrient requirements.Extensive experience from Japan, where the success of Seriola spp. farming has been based on an integrated system between producer associations, research institutes and central government, it is clear that the aforementioned technical bottlenecks need to be addressed within a framework of medium-term public policies supporting aquaculture development.Key words: Aquaculture diversification, Amberjack, Carangids, Seriola dumerili, Seriola lalandi, yellowtail Page 2 of 38 URL: http://mc.manuscriptcentral.com/brfs Email: sandra.shumway@uconn.edu 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 Reviews in Fisheries Science IntroductionDiversification is an urgent need for aquaculture (Teletchea and Fontaine, 2014) and new candidate species must be highly appreciated by consumers so to get high prices on the market. Seriola spp., belonging to the Carangidae family, are one such group of fish with exceptional consumer acceptance. The species within this family with the longest history of commercial farming is yellowtail (Seriola quinqueradiata Temminck & Schegel, 1844) which has been farmed in Japan since the 1960's (Masumoto, 2002). Seriola spp. farming in Japan initially relied on collection of wild juveniles, caught in Spring and grown until they reached market size (2-5 kg) (Masumoto, 2002). lalandi) has the second highest production volume within Seriola species, with an annual production estimated at 4558 tonnes in Japan in 2013 and 3000-4000 tonnes (expected to increase in the near future to ≥5000 t) in South Australia (Miller et al., 2011) (Fig. 1).Yellowtail kingfish is a temperate and subtropical epipelagic species naturally occurring in the Australasian region, Southern Japan and East China Sea. It has a good adaptability to cage culture conditions. Seriola lalandi is currently farmed in Japan (Nakada, 2008; Shiraishi et al., 2010), New Zealand (Kolkovski and Sakakura, 2004, Camara and Symonds, 2014 Symond...
