Effects of replacing fish oil with palm oil in diets of Nile tilapia (Oreochromis niloticus) on muscle biochemical composition, enzyme activities, and mRNA expression of growth-related genes
Fisheries and Aquatic Sciences - Tập 22 - Trang 1-9 - 2019
Due to the continuous demand for fish coupled with decline in capture fisheries, there is the need to increase aquaculture production to meet the demand. Aquaculture is faced with high cost of feeding since fish oil and fish meal are expensive. In view of this, there are calls to explore alternatives that are cheap and reliable. This study on Oreochromis niloticus was conducted to evaluate the eff......
Estimation of primary production of the waters around rack oyster farm at Wando, Korea
Fisheries and Aquatic Sciences - Tập 21 - Trang 1-7 - 2018
To establish a comprehensive management strategy, as part of the optimization of cultural practice for an oyster rack culture system, we used a numerical model to estimate the primary production in the waters on the eastern coast of Wando island, South Korea. The estimated primary production ranged from 17.12 to 1052.55 mgC m−2 day−1 (204.22 ± 224.75 mgC m−2 day−1 in average). Except for the times......

Taurine supplementation in diet for olive flounder at low water temperature
Fisheries and Aquatic Sciences - Tập 20 - Trang 1-8 - 2017
The objective of this study was to examine the effect of dietary supplementation of taurine for juvenile olive flounder (Paralichthys olivaceus) at low water temperature (16.4 ± 0.36 °C). Fish meal (FM)-based diet was used as the control diet. Four other experimental diets were prepared by adding taurine to FM-based diet at 0.25, 0.50, 1.00, and 1.50% (T1, T2, T3, and T4, respectively). Each exper......
First record of a reticulated toadfish, Arothron reticularis (Tetraodontiformes: Tetraodontidae), in Korea
Fisheries and Aquatic Sciences - Tập 23 - Trang 1-5 - 2020
A single specimen of Arothron reticularis (398 mm in total length), belonging to the family Tetraodontidae, was collected in the coastal waters off Hansan island using a set net in May 2019. The morphological characteristics of the specimen are as follows: large eyes and mouth, white spots on the body, and a white line surrounding the eyes in an annular shape. A result of maximum likelihood tree s......
Molecular cloning of metal-responsive transcription factor-1 (MTF-1) and transcriptional responses to metal and heat stresses in Pacific abalone, Haliotis discus hannai
Fisheries and Aquatic Sciences - Tập 20 - Trang 1-13 - 2017
Metal-responsive transcription factor-1 (MTF-1) is a key transcriptional regulator playing crucial roles in metal homeostasis and cellular adaptation to diverse oxidative stresses. In order to understand cellular pathways associated with metal regulation and stress responses in Pacific abalone (Haliotis discus hannai), this study was aimed to isolate the genetic determinant of abalone MTF-1 and to......
Effects of incubation temperature on the embryonic viability and hatching time in Russian sturgeon (Acipenser gueldenstaedtii)
Fisheries and Aquatic Sciences - Tập 21 - Trang 1-8 - 2018
Russian sturgeon (Acipenser gueldenstaedtii) is an emerging candidate species in the Korean aquaculture domain owing to its highly valued caviar. Although the embryonic development of this species was previously described, the complete image data on the morphological differentiation of developing embryos have not been yet fully available. Further, with the viewpoint of larval production in hatcher......
Identification of sex-specific SNPS in burbot Lota lota using RAD sequencing: conservation and management applications
Fisheries and Aquatic Sciences - - 2019
The development of sex-specific genetic assays in a species provides both a method for identifying the system of sex determination and a valuable tool to address questions of conservation and management importance. In this study, we focused on the identification of single nucleotide polymorphisms (SNPs) that differentiate genetic sex in burbot Lota lota. Burbot are the only true freshwater represe......
Padina boryana, a brown alga from the Maldives: inhibition of α-MSH-stimulated melanogenesis via the activation of ERK in B16F10 cells
Fisheries and Aquatic Sciences - Tập 23 - Trang 1-9 - 2020
The present study investigates the potent skin whitening ability of ethanol extract from the brown alga, Padina boryana (PBE) which was collected in the shores of Fulhadhoo Island, the Maldives, and its specific pathways of action. The effect of PBE which contains a rich amount of polyphenols was evaluated using B16F10 murine melanoma cells and provides insight to the underlying mechanisms with re......
Protein variation and involvement of insulin-like growth factor during embryonic development in the olive flounder Paralichthys olivaceus
Fisheries and Aquatic Sciences - Tập 21 - Trang 1-5 - 2018
Insulin-like growth factors (IGFs), along with IGF-binding protein and IGF receptor, are well-known regulators in the growth and survival of vertebrates. In this study, we investigated the involvement of IGFs and protein variation during embryonic development of the olive flounder (Paralichthys olivaceus). Morphological stages were divided into six main developments as blastula, gastrula, cephaliz......
