The objective of the present study was to evaluate the

rearing of Pomacentrus caeruleus at lower salinities and further

determine the condition factor (K) and growth rate under artificial

conditions.

Materials and Methods

Fish belonging to the species Pomacentrus caeruleus were

procured from Rameshwaram and Chennai, through ornamental

fish traders. They were placed in polythene bags filled with sufficient

air and transported to Bangalore. Fishes, 120 in number were

quarantined and transferred to glass aquaria (2x1x2 ft) with a 60 l

water holding capacity. The aquaria were fitted with under water

biological filters and thermostat for maintaining water temperature.

Artificial sea water was made by dissolving 25 g of commercial sea

salt in 975 ml of water (25ppt), mixed thoroughly, allowed to settle

and then aerated for 48 hrs before use

Acclimatization at different temperatures to lower salinities :

Fish were divided into three groups of 24 each. Group 1 was used

for acclimatization at 20ºC, group 2 at 25ºC and group 3 at 30ÚC.

Initial salinity was maintained at 25 ppt. Fish belonging to each

group were divided further into four groups of 6 each based on

their length. Initial length (Total length) and weight was recorded

before the start of acclimatization process. Fish were then subjected

to the process of acclimatization to lower salinities by gradual

decrease in salt concentration. The length, weight and the body

width was recorded at 20, 15, 10 and 5ppt of salt concentration.

The temperature of water was maintained constant throughout the

experiment (48 days) and once in 2 days 30% water was changed.

Fishes were fed with boiled beef (minced heart meat) twice a day

i.e. morning and evening. Water salinity was measured using a

refractometer. pH and dissolved oxygen (DO) was maintained at

7.8-8.2 and 4.5-5.0 respectively.

    本研究的目的是評估

    在鹽度較低,飼養Pomacentrus青色進一步

    判斷病情係數(K)及增長率根據人工

    條件。

    材料與方法

    屬於的物種Pomacentrus青色的魚

    採購從Rameshwaram和欽奈,通過觀賞

    魚商。他們被安置在充滿足夠的塑料袋

    空中運送到班加羅爾。魚類,120號

    與60升隔離,並轉移到玻璃水族箱(是2x1x2英尺)

    持水能力。配備水下水族館

    生物過濾器和溫控器保持水溫。

    是由人工海水溶解25克的商海

    在975毫升水(25ppt)鹽,充分混合均勻,靜置

    然後曝氣使用48小時前

    在不同溫度下,以較低的鹽度馴化:

    魚被分為三組各24。組1被使用

    在20℃,在25ºC組和3組230ÚC馴化。

    初步鹽度保持在25個百分點。魚屬於各

    組進一步分為四組,每組6基於

    其長度。記錄初始長度(總長度)和重量

    開始前的馴化過程。然後魚

    逐步降低鹽度馴化過程中

    鹽的濃度的降低。的長度,重量和身體

    寬度錄得20,15,10和5個百分點鹽濃度。

    的水的溫度保持恆定在整個

    實驗(48天),並在2天一次,30%的水改變。

    水煮牛肉(剁碎的肉心臟)一天兩次餵食魚類

    即早晨和傍晚。水鹽度測定採用

    折射。 pH值,溶解氧(DO)維持在

    分別為7.8-8.2和4.5-5.0。
