“…The novel lipid distribution patterns demonstrated in the present study enabled us to comparatively discuss their potential functions. For example, the clown knifefish accumulated their lipids in the anal soft finrays (see Figure 8), which could be functionally similar to those observed in the inclinator muscle of fins in the Indian spiny turbot and Japanese flounder (Kaneko, Shirakami, Hirano et al, 2016;Khieokhajonkhet et al, 2014).…”

“…The oil red O staining was performed to localize lipids in fish crosssections according to previous reports with slight modifications (Kaneko, Shirakami, Hirano et al, 2016;Khieokhajonkhet et al, 2014). Briefly, stock solutions of oil red O were prepared by completely dissolving 0.5 g of oil red O (Merck) with 100 ml isopropanol (Ajax FineChem) using a magnetic stirrer.…”

“…For example, torafugu ( Takifugu rubripes ) stores their lipids almost exclusively in the liver even when overfed (Ando, Mori, Kakamura, & Sugawara, ; Kikuchi, Furuta, Iwata, Onuki, & Noguchi, ), whereas steelhead trout ( Oncorhynchus mykiss ) and salmon ( Salmo gairdneri ) preferably depot their lipids in skeletal muscle (Sheridan, ; Sheridan, Allen, & Kerstetter, ). Japanese flounder has many adipocytes in the inclinator muscle of fin of both ocular and blind sides, suggesting that these sites are the energy reserve during continuous and aerobic movement of the fin (Kaneko, Shirakami, Hirano et al, ; Khieokhajonkhet, Kaneko, Ohara, Shirakami, & Ushio, ). Such lipid accumulation patterns in teleost fish are more diverse than in other vertebrates (Sheridan, ), especially within the skeletal muscle.…”

“…Such lipid accumulation patterns in teleost fish are more diverse than in other vertebrates (Sheridan, ), especially within the skeletal muscle. However, to our knowledge, there are only three reports on body lipid depot using whole body fish cross‐sections (Kaneko, Shirakami, Hirano et al, ; Khieokhajonkhet et al, ; Wu et al, ). Lipid distribution patterns should be investigated for each species in order to improve the efficiency of aquaculture.…”

“…The mechanism underlying lipid deposition and mobilization has been an important research topic in the aquaculture field because the lipid deposition pattern is related to flesh quality (Regost, Arzel, Cardinal, Laroche, & Kaushik, 2001) and the yield rate of aquaculture products, and also because lipid accumulation patterns in teleost fish are more diverse than in other vertebrates (Sheridan, 1988), especially within the skeletal muscle. However, to our knowledge, there are only three reports on body lipid depot using whole body fish cross-sections (Kaneko, Shirakami, Hirano et al, 2016;Khieokhajonkhet et al, 2014;Wu et al, 2015). Lipid distribution patterns should be investigated for each species in order to improve the efficiency of aquaculture.…”

Lipid distribution pattern is an important trait, which is related to flesh quality and the yield rate of aquaculture products. Here we investigated lipid distribution patterns by oil red O staining for nine economically important fish in Thailand. The most remarkable feature was that Siluriformes species had a thick layer of subcutaneous lipids, possibly to compensate the evolutionary loss of scales. In addition, we found several other characteristic staining patterns: (1) dotted stains at the boundary of red and white muscles and along the subcutaneous tissue in crystal‐eyed catfish, (2) double lines of staining along the subcutaneous layer in crystal‐eyed catfish, (3) dotted stains along the horizontal septum lines in hybrid catfish, (4) pronounced retroperitoneal fat accumulation in Nile tilapia and red tilapia, (5) pronounced fat accumulation in the inclinator muscle of the fins in Indian spiny turbot, (6) intense staining under the scales of common carp and (7) three dotted stains in soft finrays in clown knifefish. Although lipid distribution patterns are known to be affected by environmental conditions, the observed species differences suggest the strong genetic control of lipid distribution. This trait should be considered as a target of selective breeding especially for Siluriformes, in addition to commonly used parameters such as growth rate and disease resistance.

Aquaculture is one of the most developing sectors worldwide, and it contributes to enhancing the global production. The application of natural feed additives is an external source of aquaculture production due to the ban on antibiotics as a growth promotor as well as their harmful effects on the host, and costeffectiveness. Even consumer concerns those antibiotics can cause the water quality and growth instead of growth promoters of natural feed additives to improve the aquaculture production. The role of feed additives is to control the pathogenic microbes, enhance their growth, immune stimulation, and ensure water quality. For these reasons, several types of dietary feed additives are used in the livestock sector, such as essential oil, essential fatty acid, probiotics, prebiotics, symbiotic, and exogenous enzymes, but here, the feed additives of probiotics' most relevant applications in the aquaculture field in terms of modes of action such as strengthening the immune response, competition of binding sites, production of antipathogenic substances, and growth performance competition for nutrition are described. These additives are considered to be useful for their specific medicinal properties and eco-friendly metabolism in the digestive system. This review describes the role of various feed additives and their relevance to aquaculture production quality.
