“…The present study also revealed a positive correlation in the growth rate of cobia with higher saline conditions during summer months, but no such correlation was observed in the case of Asian seabass. In contrary, higher growth and feed conversion efficiency in Atlantic halibut were recorded by Imsland et al (2008) at 16 ppt salinity. Wu (1995) emphasised the importance of environmental impact assessment (EIA) for sustainable development of mariculture industry.…”

(Linnaeus, 1766) in relation to the water and sediment quality of marine farm at Karwar for two consecutive crops (2012-13 and 2013-14) were analysed. No significant variation was observed in the specific growth rate (SGR) of both the species between the crops. But within a crop, variations were observed in the SGR and absolute growth rate (AGR) of both the species (p<0.05). Specific growth rate of cobia was 0.75 and 0.78 % day -1 in 210 days of culture for the years 2012-13 and 2013-14 respectively. Physico-chemical parameters of water at cage and reference sites did not vary significantly, except for ammonia-nitrogen and nitrate-nitrogen levels at cage site between and within the crops. No significant variation was observed in total bacterial and Vibrio loads of water in cage site between the crops but significant variation was observed within the crop. The results revealed that temperature (r = +0.61 for 2012-13 and +0.63 for 2013-14) and salinity (r = +0.6 for 2012-13 and +0.5 for 2013-14) played a major role on SGR of cobia during both the crops with higher AGR recorded during summer months. In case of Asian seabass, no significant impact of temperature and salinity on SGR was noticed during the experimental period.

“…Several studies indicate that oligohaline water (<5 ppt) for fresh water fish (Wang et al, 1997;Altinok and Grizzle, 2001;Fashina-Bombata and Busar, 2003;Luz et al, 2008;Kangombe and Brown, 2008;Overton et al, 2008) and isosmotic water (10 to 15 ppt) for marine fish (Imsland et al, 2001;Rubio et al, 2005;Resley et al, 2006;Arjona et al, 2008;Imsland et al, 2008) cause more rapid growth. In isosmotic water, food uptake and growth rate increases.…”

“…There are various studies on the effects of these factors on growth (Clarke et al, 1981;Wang et al, 1997;Swanson, 1998;Altinok and Grizzle, 2001;Imsland et al, 2001;Moustakas et al, 2004;Wuenschel et al, 2004;Engstrom-Ost et al, 2005;Resley et al, 2006;Imsland et al, 2008;Kangombe and Brown, 2008;Kearney et al, 2008;Luz et al, 2008;Overton et al, 2008;Arjona et al, 2009). Nowadays, it is known that salinity affects fish growth rate but how it influences it is not totally understood.…”

The effects of four different salinities (SW, 50% SW, 100% SW and 150% SW) on specific growth rate, weight gain, food intake and survival of goldfish and crucian carp were investigated for 20 days. Both species were respectively adapted to water source, which has salinity of 8 ppt in the experimental unit for one month and then transferred to SW (8 ppt), 50% SW (12 ppt), 100% SW (16 ppt) and 150% SW (20 ppt) experimental treatments. Four goldfish fish and three crucian carp fish were placed in each aquarium. They were fed with commercial feed (Tetra Pond) to satiation twice a day and individually weighed at weekly interval. The final weight of the goldfish reared in the SW (938 ± 486 mg) and 50% SW (723 ± 269 mg) was significantly larger than that of fish reared in the 100% SW (475 ± 114 mg) and 150% SW (106 ± 318 mg). The specific growth rate was the highest in the SW (SGR: 0.53 ± 0.270% day-1) and the lowest in the 150% SW (SGR: 0.06 ± 0.195% day-1). Food intake was higher in the first three treatment groups (10.33 ± 0.572; 10.86 ± 0.917; 10.17 ± 0.767 g, respectively) than in the 150% SW (7.75 ± 1.612 g). Survival was not significantly different in the four salinity treatments (81.20 ± 23.94 ton 100.00 ± 0.00%). The final weight of the crucian carp breeding in the SW (860 ± 220 mg) and 50% SW (848 ± 394 mg) were significantly higher than the other two treatment groups. It was the worst in the 150% SW (-15 ± 903 mg). Specific growth rate was higher in the SW (SGR: 0.22 ± 0.040% day-1) and 50% SW (SGR: 0.30 ± 0.103% day-1) than the other two treatment groups. It was the lowest in the 150% SW (-0.06 ± 0.300% day-1). Food intake was higher in the first three treatment groups (8.70 ± 1.352; 7.25 ± 0.540; 7.06 ± 0.647 g, respectively) than in the 150% SW (5.60 ± 1.875 g). Survival was significantly influenced in the 150% SW (83.33 ± 19.24%). In conclusion, both species can be transferred to brackish water having not more than 8 ppt salinity. The maximum salinity tolerances of goldfish and crucian carp were 20 ppt. These findings are important in aquarium fish industry.

“…Lebih lanjut dinyatakan bahwa pada Salmonids, tingkat metabolik yang lebih tinggi pada saat berada di salinitas yang lebih tinggi menggambarkan cost energi yang signifikan disertai dengan penurunan tingkat pertumbuhan dan berkorelasi positif dengan perubahan konsumsi oksigen. Imsland et al (2008) menyatakan bahwa pemeliharaan yuwana Atlantik halibut pada salinitas yang lebih rendah menghasilkan tingkat osmoregulasi dan aktivitas metabolik yang lebih rendah dan selanjutnya mengurangi besarnya energi yang digunakan/dibelanjakan sehingga menghasilkan tingkat pertumbuhan yang lebih tinggi pada salinitas yang lebih rendah dibandingkan pada salinitas tinggi.…”

Salinitas di perairan menimbulkan tekanan-tekanan osmotik yang dapat berbeda dengan tekanan osmotik di dalam tubuh organisme perairan. Hal tersebut menyebabkan organisme harus melakukan mekanisme osmoregulasi di dalam tubuhnya sebagai upaya untuk menyeimbangkan tekanan osmotik di dalam dan di luar tubuh. Proses osmoregulasi merupakan salah satu proses fisiologi yang terjadi dalam tubuh ikan untuk mengontrol konsentrasi larutan dalam tubuh agar seimbang dengan lingkungannya. Ketidakmampuan ikan dalam mengontrol keseimbangan osmotik dalam tubuhnya akan menyebabkan ikan stres dan dapat berakibat pada kematian ikan. Perubahan kondisi lingkungan juga akan mengakibatkan perubahan alokasi energi yang ada di dalam badan ikan. Energi yang seharusnya untuk pertumbuhan akan digunakan untuk melakukan aktivitas metabolisme yang meningkat sebagai akibat dari perubahan kondisi lingkungan. Hal tersebut mengakibatkan terhambatnya proses pertumbuhan. Review yang dilakukan bertujuan untuk mengetahui aktivitas osmoregulasi, respons pertumbuhan, dan energi yang digunakan pada ikan yang dipelihara dalam media bersalinitas. Beberapa hasil penelitian menunjukkan adanya perbedaan tingkat metabolisme dan pertumbuhan pada ikan yang dipelihara pada kondisi salinitas yang berbeda.
