The Relationship

The relationship between oxygen consumption rate (milligrams per kilogram per hour) and sustained swimming speed (calculated from tailbeat frequency) was determined for 1.2-g juvenile coho salmon (Oncorhynchus kisutch) at 15 °C. The data are best described by the following equation: log oxygen consumption rate = 2.2 + 0.13 (body lengths-s−1). This relationship is very similar to that extrapolated for sockeye salmon (O. nerka) of the same size, thus potentially enabling researchers to utilize the extensive sockeye data base to predict metabolic rates of coho. The oxygen consumption rate during burst swimming (9 body lengths∙s−1) was also determined. The burst swimming metabolic rate (38 000 mgO2∙kg−1∙h−1) is nearly 40 times greater than the maximum sustained swimming metabolic rate.

<p><strong><em>Abstract.</em></strong><em> The aims of the study were: (1) to test oxygen consumption of Anadara granosa under sub-lethal concentrations of endosulfan, (2) oxygen consumption under sub-lethal concentrations of glifosat and (3) oxygen consumption under mixture of endosulfan and glifosat. </em><em>Complete randomlizeddesign were applied on this experiment.</em><em> Initially, the oxygen consumption was standardised against animal’s dry flesh weight. Results showed that dry flesh weight afffected significantly the oxygen consumption.  The relationship between the two variables was formulated as  y = 0</em><em>.</em><em>217 + 0</em><em>.</em><em>243x.  Based on teh relationship, the oxygen consumption was reported as mg/l/hr of 1g standard animal.  Exposure of blood cockles to various sub-lethal concentrations of pesticides showed that the oxygen consumption rates reduced as the concentrations increased.  For endosulfan, the oxygen consumption rate decreased from </em><em>(</em><em>0</em><em>.</em><em>5325 ±</em><em> 0.1556)</em><em>mg/l/hr at 0</em><em>.</em><em>05 ppm to </em><em>(</em><em>0</em><em>.</em><em>2282 ±</em><em> 0.1552 ) </em><em>mg/l/hr at 0</em><em>.</em><em>5 ppm.  Increasing glifosat from 50 ppm to 200 ppm reduced the oxygen consumption from </em><em>(</em><em>0</em><em>.</em><em>3111±</em><em> 0.1811)</em><em>to </em><em>(</em><em>0</em><em>.</em><em>2449 ±</em><em> 0.2548)</em><em>mg/l/hr.</em><em> </em><em>Accordingly, the oxygen consumption decreased from </em><em>(</em><em>0</em><em>.</em><em>3376±</em><em> 0.972)</em><em>mg/l/hr to </em><em>(</em><em>0,2841±</em><em> 0.2057)</em><em>mg/l/hr</em><em> </em><em>when concentrations of mixture endosulfan + glifosat mixture increased from 0</em><em>.</em><em>005 + 50 ppm to 5 + 200 ppm.</em></p><p><strong><em>Keywords:</em></strong><em> pesticide</em><em>; </em><em>endosulfan</em><em>;</em><em> glyphosate</em><em>;</em><em> Anadara granosa</em><em>;</em><em> bioassay</em><em>;</em><em> oxygen consumption</em></p><p><strong> </strong></p><p><strong>Abstrak.</strong><strong> </strong>Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi sublethal endosulfan, glifosat, dan secara bersama-sama terhadap konsumsi oksigen kerang darah (<em>Anadara granosa</em>). Metode eksperimental dengan rancangan percobaan Rancangan Acak Lengkap (RAL) diterapkan dalam penelitian ini. Hasil penelitian menunjukan bahwa berat tubuh mempengaruhi laju konsumsi oksigen dengan hubungan <em>y = 0,217+0,243 x</em>, sehingga hasil pengukuran laju konsumsi oksigen dinyatakan sebagai mg/l/jam per 1 gram berat kering kerang standar. Pemaparan terhadap konsentrasi sublethal menunjukkan bahwa laju konsumsi oksigen menurun seiring dengan meningkatnya konsentrasi masing – masing pestisida maupun campurannya.  Untuk endosulfan, laju konsumsi oksigen menurun dari (0,5325± 0,1556) mg/l/jam pada 0,05 ppm menjadi (0,2282 ± 0,1552) mg/l/jam pada 5 ppm.  Untuk glifosat, laju konsumsi oksigen menurun dari (0,3111± 0,1811) mg/l/jam pada 50 ppm menjadi (0,2449 ± 0,2548) pada 200 ppm, sedangkan untuk campuran endosulfan + glifosat, laju konsumsi oksigen menurun dari (0,3376± 0,972)  mg/l/jam pada 0,005 + 50 ppm menjadi (0,2841± 0,2057) mg/l/jam pada 5 + 200 ppm.  Kisaran konsentrasi sublethal ini sangat mempengaruhi konsumsi oksigen kerang darah (<em>Anadara granosa</em>) yaitu laju konsumsi oksigen akan menurun jika konsentrasi endosulfan dan glifosat ditingkatkan. </p><strong><em>Kata kunci</em></strong><em>: pestisida; endosulfan; glifosat; Anadara granosa; bioassay; konsumsi oksigen</em>

Microbial efficiency in a meromictic reservoirIndices of microbial efficiency (expressed as oxygen consumption and carbon dioxide release) were determined in the water column of the meromictic Piaseczno Reservoir (in an opencast sulphur mine), which is rich in sulphur compounds. Phytoplankton abundances were low in both the mixolimnion (up to 15 m depth) and monimolimnion (below 15 m depth). In summer and winter, carbon dioxide release was 3-fold and 5-fold higher, respectively, in the monimolimnion than in the mixolimnion. Laboratory enrichments of the sulphur substrate of the water resulted in a decrease in oxygen consumption rate of by about 42% in mixolimnion samples, and in the carbon dioxide release rate by about 69% in monimolimnion samples. Water temperature, pH and bivalent ion contents were of major importance in shaping the microbial metabolic efficiency in the mixolimnion, whilst in the monimolimnion these relationships were not evident.
