Paiche ( Arapaima gigas ), is a colossal freshwater fish native to the Amazon basin. Its geographic distribution spans various regions, including Brazil, Peru, Colombia, and Guyana, making it a significant component of the aquatic ecosystems in this area. Beyond its ecological role, the paiche holds substantial importance as a valuable fish resource for local communities, providing sustenance and economic opportunities. This review provides a comprehensive analysis of the reproductive aspects of the paic-he, based on information published from January 2000 to January 2022. It encompasses a wide range of reproductive characteristics, including sexual differentiation, age at first maturity

The bio-logging method could be a valuable approach to studying the underwater movement of marine fish. We investigated the horizontal and vertical movement patterns of two yellowtails Seriola quinqueradiata weighing 8.7 kg and 9.5 kg with a pop-up satellite archival tag from October 2020 to January 2021 in the East Sea of Korea. Our results showed that a yellowtail migrated northward in October and November, and then shifted southward in mid-December. The average swimming depth and temperature of the fish monitored over 82 days were 24.9 ± 9.3 m (average ± SD) and 16.5 ± 1.9 ℃ , respectively, and the total traveled distance was 1,172.4 km. The fish swam significantly deeper during the daytime (33.70 ± 14.80 m) than at nighttime (20.65 ± 8.44 m) from November to December ( p < 0.05). These results suggest that the horizontal migratory route of yellowtails in accordance with the East Korea Warm Current which is the main branch of Tsushima Warm Current in the fall and early winter seasons, and showed significant diel vertical movement patterns from November to December.

Biometric evaluation and reproductive biology of Oreochromis niloticus were studied from Geray Reservoir. Between November 2021 and August 2022, 316 O. niloticus specimens were collected from this reservoir. The observed male to female sex ratio was 1:1.14, which was statistically insignificant compared with the hypothetical 1:1 sex ratio (X 2 = 1.27, p > 0.05). The length-weight relationship was curvilinear with allometric growth (b < 3) and statistically significant from the expected isometric growth pattern (b = 3). The regression equation for females was TW = 0.0264TL 2.72 (r 2 = 0.90, n = 168), males (TW = 0.0183TL 2.79 , r 2 = 0.93, n = 148), and combined sexes (TW = 0.0229TL 2.76 , r 2 = 0.91, n = 316). Gonadosomatic index (GSI) ranged from 0.8 to 1.4 (males) and 1.8 to 4.9 (females). The breeding season lasted from March to June, with a GSI peak in April. Fecundity ranged from 279 to 1,528 eggs./fish, with a mean of 1,025 eggs./fish. The correlation between absolute fecundity and length was more significant (F = 0.76TL 2.8 , R 2 = 0.94, p < 0.05) than with weight (F = 17.683TW 0.71 , R 2 = 0.92, p < 0.05). This study provides basic information on the biology of O. niloticus in the Geray Reservoir for future fishery management tools for the conservation and utilization of this valuable freshwater fish.

Obesity is a disease involving mechanisms of fat accumulation, low-grade inflammatory cytokine release, and mitochondrial dysfunction. The aim of the current study was to investigate the effects of abalone intestine extract on fat metabolism in 3T3-L1 adipocytes and high fat diet-induced zebrafish larvae. The total phenol content was highest in subcritical water extract at 210 ℃ (SW210) among hot water, ethanol, and subcritical water extracts of abalone intestine. In addition, SW210 of male abalone intestine (MASW210) most effectively controlled the lipid accumulation and expression of adipogenic or lipogenic regulators (PPAR-γ, C/EBPα, SREBP-1c, and FAS) in 3T3-L1 adipocytes. Likewise, in zebrafish larvae fed high fat, MASW210 significantly suppressed body weight, glucose levels, and lipid accumulation. The mRNA expression related to adipogenesis (PPAR-γ and C/EBPα), lipogenesis (SREBP-1c and FAS), inflammatory cytokines (TNF-α and IL-6), energy m/;.etabolism (AMPK, lepr, SIRT1, and adiponectin), and mitochondrial biogenesis (PGC-1α and CPT-1) were significantly regulated by treatment with MASW210. These results suggest that abalone intestine extract such as MASW210, are useful biomaterials for improving obesity and metabolic diseases.

Heavy metals are naturally found in the ecosystem, and their presence in the freshwater river is increasing through anthropogenic activities which pose a threat to living beings. In this study, heavy metal concentrations (Zn, Mn, Cu, Cd, Cu, Cr, Pb, and Ni) in different organs (muscle, skin, and gill) of fish from the Padma River were evaluated to quantify, and compare the contamination levels and related human health risks. The results revealed that the heavy metal concentrations in the water, surface sediments, and fish taken from the Padma River were far below the WHO/USEPA’s permitted limits. The estimated daily intake (EDI) value in muscle was less than the tolerable daily intake (TDI). The target hazard quotient (THQ) and hazard indexes (HI) were less than 1, showing that consumers face no non-carcinogenic risk (CR). CR values of Cu, Cd, Cr, Pb, and Ni ranged from 4.00 × 10 –8 to 6.35 × 10 –6 , less than 10 –4 , and total carcinogenic risk (CRt) values ranged from 9.85 × 10 –6 to 1.10 × 10 –5 , indicating some pose a CR from consumption of those fish from the Padma River. To establish a more accurate risk assessment, numerous exposure routes, including inhalation and cutaneous exposure, should be explored.

Particulate matter (PM) is a mixture of microscopic solid inhalable particles including airborne liquid droplets, and it is implicated with several diseases. The eye does not have a protective barrier among the human organs, consequently it get directly exposed to environmental substances such as PM. The scarcity of treatments for damage to the eyesight and the vision and eye structure being closely related to the structure and function of the central nervous system highlights the cruciality of novel therapeutics. In this study was conducted using in vivo zebrafish vertebrate model which is a useful model due to the conserved genes be-tween human. We found that protective effect of Octopus minor extract against particulate matter-induced adverse effects on eye development in zebrafish ( Danio rerio ) embryos by regulating antioxidant and anti-inflammatory mRNA expression.
