Advancing production of marine fish in the United States: Olive flounder, Paralichthys olivaceus, aquaculture

Abstract

The potential for marine aquaculture development in the United States is significant and recent factors have highlighted the benefits of developing a shortened seafood supply chain to service domestic markets. Marine finfish in particular hold tremendous potential as technological advancements, improvements in production efficiencies, and market forces have aligned to create opportunities for growth within this sector of the aquaculture industry. Olive flounder, Paralichthys olivaceus, also commonly known as the Japanese flounder or hirame, is a candidate species for the U.S. aquaculture industry, which has a demonstrated track record of culture success and high market value. Although cultivation of the species is novel to the United States, olive flounder has been produced commercially for decades in other regions, notably Korea and Japan. With a number of favorable production characteristics, including a relatively short growout time compared with other flatfish species, an efficient food conversion ratio, and a wellestablished market presence, the species has been shown to be commercially viable. This study examines the opportunities for olive flounder to be developed in the United States, while also discussing the potential for land-based recirculating aquaculture systems culture of this species in

Assessment of Safety, Effects, and Muscle-Specific Accumulation of Dietary Butylated Hydroxytoluene (BHT) in Paralichthys olivaceus

“…Likewise, another study with BHA also reported a decrease in triglyceride levels with a corresponding increase in dietary BHA inclusion [ 49 ]. A possible reason for such observations with triglyceride levels has been attributed due to the antioxidant activity of BHT, which may alleviate the abnormal intracellular events involved in lipid metabolism [ 30 , 32 , 33 ]. Furthermore, considerable changes in the hematological parameters of aquatic species have been reported following exposure to different stress conditions caused by pollutants, diseases, and hypoxia [ 50 ].…”

“…Olive flounder aquaculture ranked first in terms of production volume and economic value (43,813 metric tons and US $369 million in 2021) in the Republic of Korea [ 28 , 29 ]. Owing to its excellent taste, high market demand, and rapid growth rate, the olive flounder is also considered an ideal candidate for US land-based aquaculture [ 30 ]. The nutrient requirements of this species have been well defined, and commercial feeds are locally available and exported to other countries.…”

Fish Meal Substitution Effects with the Combined Animal Proteins in the Feeds of Olive Flounder (Paralichthys olivaceus) on Growth Performance, Feed Availability, and Disease Resistance against Streptococcus iniae

“…Values (mean of triplicate ± SD) in the same column sharing the same superscript letter are not significantly different (p > 0.05). 1 Feed efficiency (FE) = weight gain of fish/feed consumption. 2 Protein efficiency ratio (PER) = weight gain of fish/protein consumption.…”

“…Olive flounder (P. olivaceus) is an endemic fish species distributed from the Western Pacific Ocean to Japan's Kuril Islands and the South China Sea and is a popular flat fish in Eastern Asia, particularly in the Republic of Korea [1]. It is a predatory fish that feeds primarily on mysid crustaceans during its larval and juvenile stages and preys on vertebrates such as wild fish as it grows [2].…”

Temperature induces metabolic reprogramming in fish during bacterial infection

“…Flounder (alternative names: Japanese flounder, olive flounder) is a species of marine teleost extensively cultured in Asia, in particular China, Japan, and Korea, and is extensively used as an experimental model in the studies on fish disease ( 9 – 13 ). The physiologically suitable temperatures of flounder range from 14°C to 23°C ( 14 – 16 ). In farmed flounder, edwardsiellosis is one of the most severe diseases, which occurs more frequently at high temperatures and can lead to mass mortality in numerous fish species farmed worldwide ( 17 – 20 ).…”
