dc.description.abstract The present study aimed to assess the pisciculture status in Gaza strip. Field surveys and questionnaire interviews (n = 160) were applied to collect data concerning pisciculture sector. The present study revealed that five pisciculture projects ranging from 1200 to 5000 m2 are functioning in Gaza strip. Five farmed fish species; Oreochromis hybrids, Oreochromis niloticus, Sparus aurata, Mugil cephalus and Clarias gariepinus have been cultured. Beach wells are the main water source for most projects. The fish fry of Sparus aurata and the fish feedstuffs have been imported from the Palestinian teritories occupied. Marine fishes have been preferred by 42.5% of respondents over farmed ones due to health and taste standards. Most respondents (81.9%) confirmed the lack of marketing operations and electronic advertising of framed fishes. The findings pointed out that 98.1% of respondents confirmed certain challenges facing pisciculture in Gaza strip. Financial, technical, scientific, political and policy-making problems are functioning, with the fuel and electricity shortages are main problems. Two types of water samples were collected and analyzed for some physicochemical parameters. Concentrations of Cd, Cu, and Pb were determined in pond waters as well as in the white muscles of 40 samples of the three local farmed fish species: Oreochromis niloticus, Oreochromis hybrids, and Sparus aurata, using atomic absorption spectroscopy. pH, conc. of nitrate, nitrite and ammonia were ranging from 7.01-7.69, 11 - 41 mg/l, 0.11 - 0.17 mg/l, 0.1 - 0.19 mg/l respectively in all water samples and this values doesn’t exceed the international maximum standard limits. Electrical conductivity, alkalinity, total dissolved solids, hardness and chloride were ranging from 1743 - 55000 μs/cm, 147 - 360 mg/l, 1115 - 34100 mg/l, 100 - 7512 mg/l, 400 -19380 mg/l respectively and this values exceed the international maximum standard limits. The concentrations of both Cd and Pb in V the water samples were ranging from 42.1 – 92.57, 48.5 – 96.2 μg/l respectively, and in fish samples were ranging from 0.59 – 2.08, 4.16 – 10.36 μg/g wet weight respectively, this values exceed the international maximum standard limits, compared with the concentration of copper which ranging from 109.7 – 183.2 μg/l in water and 0.08 – 1.41 μg/g wet weight in fish, this values doesn’t exceed the international maximum standard limits. Pisciculture projects are a promising sector in Gaza strip. Cooperation between the different parties regarding the fisheries resources including the pisciculture should be raised in a sustainable fashion. en_US
