The constant and accelerated increase of world fish production through the expansion of fisheries and the development of aquaculture has also generated a higher interest in animal welfare. In the present, is proven that the fish welfare is a factor that influences the quality of the product and the practices of capture and slaughter, which can compromise these attributes. The harvesting and suppressing life methods give to the biochemical processes of fish meat some particularities, as a result of the stressor to which it is subjected by tracking, agglomeration, space restriction and asphyxiation. In the view of all, it is important to correctly identify procedures that improve both the welfare of the fish and the quality of the product. In this review, there are highlighted some of the stunning and slaughter methods of fish used in the aquaculture or capture fisheries, focusing on the human agreed standards and international organizations. There are recommendations in this sense for operations prior to slaughter and the possibility of developing and implementing new methods, by country and species of fish. In this sense, the brain puncture stands out as a more humane method of slaughtering fish, which also improves the quality of the product.

The main component of the body: the water, alongside with many function which it has,represents a constituent in the diet of animal. There are many and various factors that influence the daily water requirements of animals: some dependent on animal: and others dependent on the environment. Water quality administered to livestock must meet the requirements for potability prerequisite to maintaining the health, externalization full productive potential and sustaining breeding. Knowing the importance of water quality consists in the negative action which can exert on the body to exceeding certain thresholds translated through: reducing water consumption simultaneously with the decrease milk production, decreased feed conversion rate and average daily gain, degradation of health status by reducing the local resistance, decrease overall body resistance, metabolic, digestive, skeletal disorders and impaired reproduction sphere translated through:decreasing fertility, abortions; elements interfering with the absorption of other essential water body, producing chronic or acute poisoning. The water composition plays essential role depending on which is supplemented or not as the case the quantity of the macro and trace minerals from feedingstuff according to the synergism or antagonism action between the minerals present.

Aim of this study was to assess the chemical status of water by point of view of the indicators parameters coming from the decentralized system of water supply (wells) and which supply the water of dairy farms performed in 63 wells from the same number of farms from 5 located in: S-E, N-W and central of Romania at the request of farmers. It has been studied the parameters that indicate the status of water acidification: pH (SRISO 10523/97); indicator parameters having as landmark the minimum list of parameters monitored by the laboratories of profile from county public health department: hardness (STAS 3326/76), iron (STAS 3086/68), CCOMn (STAS:3002/85), ammonia (spectrometry), parameters indicative of saline inclusions: chlorides (STAS 3049/88), sulfates (SRISO 10523/97). Characterization of the chemical state of water: good or poor was done after the values that define the worst condition. The limit values for each parameter are compared to those required by the L.107/1996, L.458/2002, 311/2004, O.621/2012. Were recorded values which attesting good quality status for 21 wells:[ 1 Buzău (BZ),12 Cluj (CJ),2 Mureş (MS),6 Sălaj (SJ)] and 42 wells whose water quality status it is poor (6 AB, 5 BZ,17 CJ, 7 MS). Exceeding the limits values were found at the parameters: CCOMn (CJ: 05.29±3.87mgO2/dm3, 10.59±2.04 mgO2/dm3 AB); ammonia: (AB: 0.56±0.08 mg/dm3, MS: 0.51±0.1 mg/dm3), iron (BZ: 0.85±1.05 mg/dm3, CJ: 0.37±0.47 mg/dm3, MS: 0.62±0.57mg/dm3), chlorides (AB: 330.42±208.8 mg/dm3, MS: 243.18±164.8 mg/dm3). Contamination risk score of wells in the studied areas is medium (3 point).

The study was performed at 63 wells that belongs to the decentralized system from the territory of 5 counties by Romania: AB- 7 wells, BZ-6 wells, CJ-33 wells, MS-1wells, SJ-6 wells taking into account the chemical parameters: nitrites (SRISO 6777/96), nitrates (SRISO 7890/1-98), report nitrates and nitrites in accordance with the L. 458/2002. Results reveals values of NO2: 0.32±0.08 mg/dm3AB, 0.23±0.08 mg/dm3 BZ, 0.33±0.05 mg/dm3 CJ, 0.23±0.03 mg/dm3 MS, 0.09±0.02 mg/dm3SJ, and NO3: 35.71±7.53 mg/dm3AB, 48.66±5.92 mg/dm3 BZ, 23.54±2.82 mg/dm3 CJ, 19.63±4.64 mg/dm3 MS, 31.16±5.12 mg/dm3 SJ which theoretically include waters in terms of two parameters in drinking water and good chemical states but, individual samples in terms of nutrient regime has exceedances influenced by poor cleaning, hygienisation and disinfection of wells.
