“…However, Zhang et al (2015) reported a significant increase in the immune responses of Megalobrama amblycephala under challenge with high concentrations of ammonia. Moreover, in Carassius auratus and Anoplopoma fimbria, the expression and activity of immune-related factors of the liver were increased under ammonia exposure (Kim et al 2017;Qi et al 2017), which were consistent with the results of this study. The functions of the hepatopancreas were related to the synthesis and secretion of immune molecules (Al-Mohanna and Nott 1989), indicating that as the first line of defense with external water, the immune response of the gills was inhibited.…”

The swimming crab Portunus trituberculatus is an important farmed species in China. Ammonia-N represents a major physiological challenge for crab culture and the hepatopancreas plays a major role in physiological adaptation processes. To better understand the molecular mechanism of the crab in response to ammonia-N stress, we performed a transcriptome analysis in the hepatopancreas of P. trituberculatus challenged with ammonia-N stress (5 mg/L), using the high-throughput sequencing technology. In total, 52,280 unigenes were obtained from the hepatopancreas of P. trituberculatus, with an average length of 678 bp. Functional categorization and pathways showed some differentially expressed genes were involved in amino acid and nucleobase metabolism, energy metabolism, antioxidation, immune response, reproduction, moulting and material transport. The differential expression patterns of eight randomly selected annotated genes were validated by quantitative real-time PCR (qPCR). Results revealed a substantial number of genes modified by ammonia-N stress and a few significant ammonia acclimation pathways, which will serve as an invaluable resource for revealing the molecular basis of physiological adaptation mechanism in P. trituberculatus.

“…River water temperature (RWT) is one of the most important indicators to determine the overall health of aquatic ecosystems since it affects various physical and biochemical processes in rivers (Rice and Jastram, 2015). For example, RWT significantly impacts dissolved oxygen dynamics (Cox and Whitehead, 2009), the formation of potentially toxic ammonia (Kim et al, 2017), and the evolution and distribution of aquatic organisms (Fullerton et al, 2018). Cingi et al (2010) stressed that relatively small increases in RWT during the spawning period of Coregonus lavaretus may lead to fatal impacts on its recruitment and population persistence.…”

The bio-chemical and physical characteristics of a river are directly affected by water temperature, which therefore affects the overall health of aquatic ecosystems. In this study, long term variations of river water temperatures (RWT) in Kupa River watershed, Croatia were investigated. It is shown that the RWT in the studied river stations increased about 0.0232-0.0796ºC per year, which are comparable with long term observations reported for rivers in other regions, indicating an apparent warming trend. RWT rises during the past 20 years have not been constant for different periods of the year, and the contrasts between stations regarding RWT increases vary seasonally. Additionally, multilayer perceptron neural network models (MLPNN) and adaptive neuro-fuzzy inference systems (ANFIS) models were implemented to simulate daily RWT, using air temperature (T a ), flow discharge (Q) and the day of year (DOY) as predictors. Results showed that compared to the individual variable alone with T a as input, combining T a and Q in the MLPNN and ANFIS models explained temporal variations of daily RWT more accurately. The best accuracy was achieved when the three inputs (T a , Q and the DOY) were included as predictors. Modeling results indicate that the developed models can well reproduce the seasonal dynamics of RWT in each river, and the models may be used for future projections of RWT by coupling with regional climate models.

Starry Flounder Platichthys stellatus were exposed to dietary lead (Pb) at concentrations of 0, 30, 60, 120, and 240 mg/kg for 4 weeks. Recover period was conducted for 2 weeks after the exposure. Exposure to Pb concentrations over 60 mg/kg induced significant changes in the antioxidant responses in the liver, kidney, and gill and continued even after the depuration period in the liver (over 120 mg/kg for superoxide dismutase [SOD] activity) and kidney (at 240 mg/kg for glutathione [GSH] levels). Glutathione S-transferase (GST) activity in liver, kidney, and gill were increased by dietary Pb exposure, and recovery was observed in all groups during the recovery period. Acetylcholinesterase (AChE) activity was significantly inhibited in the brain and muscle of flounder at Pb exposure over 120 mg/kg, and no restoration was observed after the depuration period. Lysozyme activity in the plasma was significantly increased at Pb exposures greater than 60 mg kg but was restored after the depuration period. The results of this study indicate that dietary Pb exposure induces toxic effects on antioxidant responses, neurotransmitter, and immune responses of Starry Flounder.
