“…Increased glucogenesis and glycogenolysis may have contributed to the observed rise in glucose levels as well as inhibition of glycogenolysis and glycogenesis during stress [ 39 ]. These findings are similar to the responses of other fish treated with organophosphorus pesticides such as grass carp exposed to endosulfan [ 40 ]. During the study period, glucose level was found to be decreased after exposure (14, 21, and 28 days) to malathion in both treatments (T2 and T3) compared to the control group (T1).…”

An experiment was conducted to assess malathion-induced hematological responses of Barbonymus gonionotus (silver barb) and its recovery patterns in malathion-free water. Fish (45 days old) were exposed to two sublethal concentrations, namely, 25% and 50% (i.e., 3.78 and 7.56 ppm) of LC50 (15.13 ppm) of malathion for 28 days, followed by a postexposure recovery period for the same time. The hematological parameters were examined after 1, 7, 14, 21, and 28 days of exposure as well as after the postexposure recovery time. Except in the case of the control group (0% of malathion), the obtained results revealed that malathion exposure resulted in significantly ( p < 0.05 ) higher prevalence and severity of micronucleus and lower values of Hb, PCV, and RBC and significantly higher values of WBC in a concentration- and time-dependent manner. The values of blood glucose, MCV, MCH, and MCHC showed mixed trends during the experiment. During the recovery period, all blood parameters (micronucleus, glucose, Hb, PCV, RBC, WBC, MCV, MCH, and MCHC) partially recovered, which means that the recovery period was not long enough for the organisms to recover from the previous exposure. The study thus confirms that hematology is a sensitive indicator for fish to detect toxicity caused by different chemicals. Changes in these parameters can provide useful information about environmental conditions and risk assessment of aquatic organisms.

The present study was conducted to assess the effect of oxytetracycline hydrochloride (OTC) in rohu, Labeo rohita, with graded doses viz., 80 (1×), 240 (3×), 400 (5×) and 800 (10×) mg kg −1 fish biomass day −1 respectively through feed. Four hundred and fifty healthy rohu juveniles (20 ± 0.12 g) were fed for 30 days followed by 10 days of withdrawal period. Each 10 days intervals, five fish were randomly sampled for blood, serum and tissue for estimation of growth, non-specific immune parameters, enzymatic activities and retention of OTC in muscle tissue. The results showed that there was no significant difference (p > .05) on growth in the treated fish compared with the control. Respiratory burst activity, myeloperoxidase activity, bacterial haemagglutination and haemolysis activities were enhanced significantly (p < .05) on 10 th and 20 th day in the fish fed with 80 and 240 mg kg −1 biomass day −1 respectively during the feeding trial compared with the control. Lactate dehydrogenase and alkaline phosphatase activity increased significantly (p < .05) in the fish fed with 400 and 800 mg kg −1 biomass day −1 respectively compared with the control. Liquid chromatographymass spectrometry/mass spectrometry study of muscle tissue reveals that OTC was retained in muscle tissue in a dose dependent manner and significantly (p < .05) lowest level (0.44 ± 0.03 ppb) was observed on 40 th day in the treated fish fed with 80 mg kg −1 biomass day −1 . Hence, 80 mg kg −1 fish biomass day −1 of OTC may be adhered in L. rohita for treating the fish through feed with 10 days of withdrawal period.

“…A study on carp showed that the supplementation of Zn in feed could improve protein concentration in blood and intestine (Chupani et al, 2017;2018), while on giant freshwater prawn, the supplementation of Zn was reported to improve growth, survival rate, and immunity (Muralisankar et al, 2014;. Fish feed with 20 mg/kg Zn produced the highest weight and SGR and was significantly different among other treatments (P<0.05) (Mondal et al, 2020).…”

ABSTRACT The aim of this study was to determine the optimum level of Zinc (Zn) enrichment in Artemia sp. nauplii as a live feed to improve bone formation and growth of climbing perch Anabas testudinieus larvae. The study consisted of four different Zn enrichment levels (0.0, 0.05, 0.1, and 0.15 mg/mL) in Artemia sp.nauplii. The enrichment was performed for 12 hours with the nauplii density of 1 ind/mL. Climbing perch larvae with an average initial length of 1.65 ± 0.15 mm were fed four times daily with the enriched nauplii. For the first 5 days, all larvae were fed with rotifer followed by feeding with enriched Artemia nauplii ad libitum. The results showed that the application of Artemia sp. enrichment at 0.1 mg Zn/mL influenced the bone formation, increased the growth, and improved the fish survival of climbing perch larvae. Feeding with 0.1 mg/mL Zn enriched Artemia nauplii could be recommended as a strategy to improve the bone formation and growth performance of climbing perch larvae. Keywords: Anabas testudineus, Artemia sp., climbing perch, live feed, zinc ABSTRAK Penelitian ini bertujuan menentukan dosis optimum pengayaan seng (Zn) pada naupli Artemia sp. terhadap pembentukan tulang dan peningkatan pertumbuhan larva ikan betok. Penelitian dilakukan selama 18 hari dengan empat dosis pengayaan Zn yang berbeda (0, 0,05, 0,1, dan 0,15 mg/mL) pada naupli Artemia. Pengayaan dilakukan selama 12 jam dengan kepadatan naupli 1 ind/mL. Larva ikan betok dengan ukuran panjang awal rata-rata 1.65 ± 0.15 mm diberi pakan naupli yang diperkaya sebanyak 4 kali sehari. Pada lima hari pertama, semua larva diberi pakan rotifer, diikuti dengan pemberian naupli Artemia yang diperkaya secara ad libitum. Hasil yang diperoleh menunjukkan bahwa pengayaan naupli Artemia sp. dengan Zn 0,1 mg/mL berpengaruh terhadap pembentukan tulang belakang dan dapat meningkatkan pertumbuhan serta meningkatkan kelangsungan hidup larva ikan betok. Pemberian naupli Artemia dengan Zn sebanyak 0.1 mg Zn/mL dapat direkomendasikan untuk perbaikan pembentukan tulang dan pertumbuhan larva ikan betok. Kata kunci: Naupli Artemia sp., ikan betok, pakan alami, seng
