“…Cobia are typically produced in near‐shore sea cages, in recirculating aquaculture systems and ponds, being cultured principally in Asia, Central America, and more recently in Brazil (Benetti et al, ; Liao et al, ). Although relatively few studies have been published concerning the nutrition and feeding of cobia (Estrada, Yasumaru, Tacon, & Lemos, ; Fraser & Davies, ), most existing commercial feeds in Brazil are still either based on the use of low‐cost trash‐fish‐based diets or on the use of high‐protein dry pelleted feeds.…”

“…Fishmeal is commonly considered to represent the best dietary protein source for carnivorous fish, and the development of economical and sustainable feeds will be necessary to keep aquaculture at current growth rates, meeting the worldwide demand for marine products. To reduce the use of fishmeal in cobia feeds, plant ingredients have been tested to replace fishmeal (Estrada et al, ). Chou et al () have confirmed the possibility of replacing up to 40% of the dietary fishmeal with soybean meal without compromising growth and feed utilization.…”

Three studies were conducted with juvenile cobia, Rachycentron canadum: (Study 1) a 10‐week feeding trial within floating net cages to test the nutritional efficacy of different dietary feeding regimes (trash‐fish control diet, a semimoist diet, an in‐house dry formulated diet, and a commercial cobia feed); (Study 2) a 10‐week feeding trial within an indoor water‐recirculating tank‐based system to test the nutritional efficiency of different potential dietary fishmeal replacers (poultry byproduct meal, soy protein concentrate, feather meal), a diet without taurine supplementation, and a commercial cobia feed; and (Study 3) estimation of the essential amino acid (EAA) requirements of cobia based on EAA whole‐body composition in fast‐growing cobia fed a trash‐fish‐based diet. Fish performance in terms of growth and feed efficiency was the greatest within the outdoor net‐cage feeding trial, with fish fed the control trash‐fish‐based diet exhibiting the best performance. Although fish growth was poorer within the indoor feeding trials, fish performance was similar for most diets, with apparent crude protein digestibility coefficients of over 75% being obtained in all experimental diets in both feeding trials. The estimated EAA requirements of cobia obtained during this study were similar to those reported for other similar marine carnivorous fish species.

“…In this study, we aimed to test for the combined effects of a simulated MHW and PUA on cobia (Rachycentron canadum) larvae and juveniles, one of the major marine aquaculture species (Estrada, Yasumaru, Tacon, & Lemos, 2016;Klinger, Levin, & Watson, 2017;Liao et al, 2004;Nhu et al, 2011), especially in countries around the South China Sea (Liao et al, 2004). More importantly, we tested whether both stressors interact to modulate each other's effects (Crain et al, 2008;Darling & Côté, 2008;Folt, Chen, Moore, & Burnaford, 1999).…”

“…At present, specific information on the etiology of "choke point diseases" (those constraining aquaculture production), particularly during cobia grow-out in sea cages, is predominantly lacking. Within sea cages, young cobia can be decimated by diseases variously linked to the occurrence/infection by an array of viruses, bacteria, and metazoan parasites (e.g., Shaffer and Nakamura, 1989;Chen et al, 2001;Liao et al, 2004;Bunkley-Williams and Williams, 2006;Lowry and Smith, 2006;Ogawa et al, 2006;Chu et al, 2013;McLean et al, 2013;Estrada et al, 2015). Although these symbionts are not documented to cause disease among wild cobia, they take on pathogen status when environmental conditions and fish physiological status are appropriate for the onset of disease.…”

Endocarditis associated with blood fluke infections (Digenea: Aporocotylidae: Psettarium cf. anthicum) among aquacultured cobia (Rachycentron canadum) from Nha Trang Bay, Vietnam

We herein diagnose blood fluke (Digenea: Aporocotylidae) infections in sea cagereared cobia (Rachycentron canadum) from Nha Trang Bay, Vietnam, using morphology, nucleotide sequences, scanning electron microscopy, and histopathology. This is the first report of this blood fluke beyond the Gulf of Mexico and contributes to our understanding of the disease implications of aporocotylid infections among marine aquacultured fishes. Blood flukes were morphologically identified as Psettarium cf. anthicum by having the combination of an extremely elongate body with rows of straight, ventrolateral tegumental spines and a sinistral posterolateral protuberance, an H-shaped intestine with asymmetrical posterior ceca, a lobed ovary, an ootype posterior to the male genital pore, and an extensively convoluted uterus located between the ovary and ootype. A comparison of the large subunit ribosomal DNA (28S), small subunit ribosomal DNA (18S), and internal transcribed spacer 2 (ITS2) derived from blood flukes infecting cobias in Nha Trang Bay and Gulf of Mexico revealed 5 (99.5% similarity in 28S), 3 (99.8%, 18S), and 12 (98.9%, ITS2) nucleotide differences between the geographic isolates. Adult blood flukes pierced the endocardium and penetrated the spongy myocardium or lesioned endocardium of the cobias from Nha Trang Bay. The associated heart lesion comprised fibro-granulomatous endocarditis with accompanying endocardial thrombi, including focal effacement of the endocardium adjacent to thrombi, hyperplasia of endocardial cells yielding a thickened endocardium within which adult flukes resided or fluke remnants were located, clusters of large epitheliod granulomas within thrombi and within the basal endocardium, and minute granulomas in spongy myocardium enclosing probable blood fluke eggs. These pathological alterations suggested that heavily-infected cobia may suffer reduced cardiac output via thrombi blocking normal blood flow and emboli causing infarcts. Acute mortality may be likely for heavily-infected cobias during periods of high cardiac output, e.g., during feeding in a sea cage, if concomitant with, or resulting in, circulation of emboli. The lesioned endocardium may reduce efficiency of respiratory gas exchange to cardiac myocytes as well as impair endocardial cell immune function.
