“…It is an important item in local fisheries, and its introduction has been considered for aquaculture activities (Sampaio 2006). Several studies have been conducted to improve the larviculture of O. argentinensis; and this knowledge of larval rearing has also stimulated the establishment of protocols for its use in ecotoxicologial assessment (Sampaio and Minillo 1995;Sampaio et al 2006).…”

“…High nitrate level leads to the rapid growth of unwanted lives and the reduction of dissolved oxygen. Fishes exposed to a higher nitrate concentration may have decreased hemoglobin concentration because nitrate converts hemoglobin into metahemoglobin that reduces the transportation of oxygen in aquatic animals (Sampaio et al, 2006). Figure 4b and Figure 4c reveal the concentration (mg/l) of PO4 3and SO4 2in our study area.…”

In Bangladesh, aquaculture has become an extensive practice, and over 12% of the population is involved in it. It is well-recognized that water quality determines the metabolic and physiological activities of fishes and negatively affects fish production. However, both groundwater and surface water resources in many places are affected by various pollutants. This research was conducted to assess the suitability of pond water for aquaculture in Sonadanga and Kotwali thanas in Khulna City Corporation Area of Bangladesh using spatial distribution. For doing this, samples from 23 fish cultivated ponds in those two thanas were collected for analyzing the basic physical and chemical parameters. Results revealed that only the pH of the ponds was in a favorable range (8.03 to 7.37) for aquaculture, but other water quality parameters like electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), dissolved oxygen (DO), calcium (Ca2+), magnesium (Mg2+), water hardness (WH), total iron (Fe2+ and Fe3+), sodium (Na+), chloride (Cl-), bicarbonate (HCO3-), nitrate (NO3-), phosphate (PO43-), and sulfate (SO42-) were present in excessive concentrations. The Pearson correlation among these parameters were found to be significant. Although, the water bodies in both thanas were unsuitable for fish farming, the Kotwali thana had more degraded ponds compared to the Sonadanga thana. It is recommended that the local administration should undertake necessary actions to improve the suitability of aquaculture and to conserve these water bodies in the area.

“…The flounder Paralichthys orbignyanus is the most sensitive marine fish on record with a 96 h LC 50 of 30 mg l -1 NO 2 -N [39] and the dark-banded rockfish Sebastes inermis is the least sensitive fish reported, with a 96 h LC 50 of 700 mg l -1 NO 2 -N [18]. Other species show intermediary toxicity: 85 mg l -1 NO 2 -N for red drum Sciaenops ocellatus [40] and 199 mg l -1 NO 2 -N for the marine pejerrey Odontesthes argentinensis [41]. Tolerance of S. rivulatus to short-term nitrite exposure is closest to that of Siberian sturgeon Acipenser baeri having LC 50 of 130 mg l -1 NO 2 -N [16].…”

Nitrite is toxic to fishes and is often encountered in recirculation aquaculture systems. Accordingly, the nitrite tolerance of potential aquaculture candidates needs to be assessed before the fish can be farmed in land-based recirculation systems. In the present work, we studied the susceptibility of the marbled rabbitfish Siganus rivulatus to nitrite. In the first experiment, we placed fish at 0, 40, 50, 60, 70, 80, 90, 100, 110, 120 and 130 mg l-1 NO 2-N and evaluated 96 h LC 50. In the second experiment we measured survival and growth of fish reared at 0, 10, 20, 30, 40, and 50 mg l-1 NO 2-N for eight weeks. Blood parameters of fish in the various treatments were also measured and gill histology studied. Finally, methemoglobinemia in fish reared at various nitrite conditions was assessed. The NO 2-N 96 h LC 50 of S. rivulatus juveniles was 105 mg l-1. In the growth experiment, fish mortality was greater than in the control at NO 2-N concentrations 30 mg l-1 and greater. Growth in all treatments was less than in the control but there were no significant differences among treatments. Aqueous nitrite affected various hematological parameters such as hematocrit and total hemoglobin. Compared to other aquacultured marine fishes, the marbled rabbitfish is considered tolerant to environmental nitrite.
