Glyphosate Herbicide

Background: Sub-lethal toxicity bioassay experiments were conducted to determine the toxicity of glyphosate herbicide on Koi carp, Cyprinus carpio fingerlings. Koi carp fingerlings with mean length 8.06 ± 0.99 cm were obtained from a freshwater fish seed hatchery of the university.Methods: The fishes were exposed to sub-lethal concentrations i.e. 1/10th (3.6 mgL-1) and 1/5th (6.6 mgL-1) of glyphosate. Oxygen consumption rate, Ammonia-Nitrogen excretion rate, Oxygen:Nitrogen ratio and food consumption rate were recorded after every 7 days for a period of 28 days.Result: Results indicated significant decrease (P less than 0.05) in oxygen consumption in 1/10th and 1/5th of LC50 concentrations. Ammonia-Nitrogen significcantly increased in exposed fishes. Oxygen : Nitrogen ratio and food consumption rate also significantly decreased (P greater than 0.05) in treated fishes. The results indicated that glyphosate had impacts on exposed fish, hence, the need of regulation of its usage to protect non-targeted species and the environment.

By monitoring nitrogen (ammonia and urea) excretion and oxygen consumption in a continuous manner during early development (from 18 to 350 degree days) of common carp, Cyprinus carpio, we noted high rates of ammonia-N excretion (> 100 and > 50 μgN∙h−1∙103 eggs−1) and of oxygen consumption (> 1 and > 2.5 mg∙h−1∙103 eggs−1) at hatching and at the onset of free-swimming stages, respectively. There was a diurnal rhythm in metabolic activity. The relative proportions of urea-N and ammonia-N varied during early development; the mean urea-N excretion rate amounted to 21.9 ± 8.7% of total nitrogen, and there was no significant difference between embryonic and postembryonic stages. Fasted free-swimming larvae exhibited increased metabolic activity just before the onset of massive mortality (> 75 μg N∙h−1∙103 eggs−1 and > 2 mg O2∙h−1∙103 eggs−1 of nitrogen excretion and oxygen consumption, respectively). Ammonia excretion rates increased with temperature, the Q10's being 2.36, 2.33, and 3.53 during embryonic, hatching, and free-swimming stages, respectively.Key words: carp, ontogenesis, nitrogen excretion, ammonia, urea, oxygen consumption, temperature, diurnal rhythm

Abstract: This research aims to determine the optimum density in closed system transportation of milkfish juvenile. Milkfish juveniles used in the research had an average weight 1.48±0.12 g. The study consisted of several stages, namelydetermining the ability to fast fish, determining the level of oxygen consumption, determining the rate of excretion of total ammonia nitrogen and determining the optimum density in transportation for 48 hours.The treatments were performed differences in the density of 100, 150, 200, and 250 fish/L using polyethylene plastic size 35x50 cm and styrofoam size of 75 × 43 × 40 cm.The results showed the seed fish can survive and swim actively for 7 days without feeding with oxygen consumption rate as much as 2640 mgO2 and TAN excretion rate 0.1200 mg/L. The different treatment of density had an effect on the survival rate of milkfish juvenile. The optimal density for transportation of milkfish juvenile size 1.48 ± 0.12 g in a closed transportation system with a time of 48 hours is 150 juvenile/L with a 100% survival rate. At the density 250 juvenile/L, the can be done with a long time of 30 hours and resulted in a survival rate above 99%.  Keyword: Chanos chanos, Density, Transportation closed system, Survival rate, Water Quality Abstrak: Penelitian ini bertujuan untuk menentukan kepadatan optimal dan lama waktu dalam transportasi sistem tertutup benih ikan bandeng.Benih ikan bandeng yang digunakan memiliki bobot rata-rata 1,48±0,12g. Penelitian terdiri dari beberapa tahap, yaitu penentuan ketahanan ikan tanpa diberi makan, tingkat konsumsi oksigen, laju ekskresi total amoniak nitrogen dan kepadatan optimal benih ikan bandeng dalam transportasi selama 48 jam. Perlakuan yang dilakukan perbedaan kepadatan yaitu 100, 150, 200, dan 250 ekor/L dengan menggunakan plastik polyetylen (PE) ukuran 35x50 cm dan styrofoam ukuran 75×43×40 cm.Hasil penelitian menunjukkan benih ikan bandeng mampu bertahan hidup dan berenang aktif selama 7 hari pemuasaan ikan dengan tingkat konsumsi oksigen sebanyak 2640 mgO2 dan laju ekskresi TAN 0,1200 mg/L.Perlakuan perbedaan kepadataan berpengaruh terhadap kelangsungan hidup benih ikan bandeng.Kepadatan optimal untuk transportasi benih ikan bandeng ukuran 1,48±0,12 g/ekor pada sistem transportasi tertutup selama 48 jam adalah 150 ekor/L dengan tingkat kelangsungan hidup 100%. Pada kepadatan 250 ekor/L, transportasi dapat dilakukan dengan lama waktu 30 jam dan menghasilkan tingkat kelangsungan hidup di atas 99%. Kata Kunci: Ikan bandeng, Kepadatan, Kualitas Air, Transportasi sistem tertutup, Tingkat Kelangsungan Hidup
