Quality of Meat and Some Meat Products Manufactured at SC Ferma Zootehnica SRL Baia Mare

During a period of 6 months beginnings with October 2016 until March 2017, were analysed meat products such as: Haiducesc smoked chest, Premium jambon, as well as semi-smoked assortments: Pork salami, Pintea salami and Pancetta salami obtained at SC. “Ferma Zootehnică” SRL Baia Mare. The results are reported at 100 g of product and were as follow: Haiducesc smoked chest: 31.87% water, 3.2 g salt, 2.51 mg nitrites; Premium jambon: 32.16% water, 3.38 g salt, 2.78 mg nitrites; Pork salami: 53.2% water, 2.13 g salt, 2.32 mg nitrites; Pintea salami: 51.8% water, 2.21 g salt, 2.95 mg nitrites; Pancetta salami: 46.08% water, 2.21 g salt, 2.04 mg nitrites. The obtained values fit in the allowed limits of the European norms STAS 6352/1-88 and 6353-85, therefore the products obtained are very good quality.

Physical–chemical parameters and the level of heavy metals in cow milk in the Baia Mare area

Heavy metals are important pollutants in the environment and can cause problems for the organisms, and the bioaccumulation of heavy metals in the food chain can have adverse effects on human health. Regulations on the legally accepted amounts of heavy metals in food and in the body are very precise. The purpose of this paper was to evaluate the level of heavy metals in cow milk from different localities in the Baia Mare area, considered a very polluted area. The physical–chemical parameters and heavy metals in milk were determined. The determination of heavy metals in milk was performed by inductively coupled plasma mass spectrometry or ICP– MS used to identify and quantify the Pb, Cd, Cu, and Zn elements. The highest concentrations of Pb were observed in samples collected in Firiza locality with an average value of (43.22±0.62) (μg/L) and the lowest concentrations are for the samples analyzed in Săcălăşeni (11.53±0.33) (mg/L) (μg/L). Cd in milk did not show very large variations between localities, so the lowest concentrations were recorded in Săcălăşeni (4.32±0.13) and the highest ones were observed in the locality Firiza (10.93±0.39) (μg/L). The highest concentrations were observed for the Zn in milk, with an interval between (2255.20±7.14) (μg/L) in Săcălăşeni and (3855.80±5.11) (μg/L) for the analyzed samples from Firiza. Keyword: milk, fat, proteins, Zn, Cd, Cu, Pb.

A new record of Ratan goby - Ponticola ratan (Nordmann, 1840) (Pisces: Gobiidae) in the Black Sea, Romanian coastal waters

In August 2015 we managed to capture a specimen of ratan goby ( Ponticola ratan) in the Romanian coastal waters of the Black Sea, near the locality of Sf. Gheorghe (Tulcea County). This is the 7 -th signaling for this species in Romanian coastal waters. The previous 6 specimens were recorded in the period 1960-1993, between Mangalia (ConstanA£a County) and Sulina (Tulcea County). The species was identified by means of meristic characters (number of scales on medial line, number of spiny and soft rays), and morphological particularities (cycloid scales on the nape area and pectoral fin joint). Also, the measurements made, confirmed that the ratio between the head length and total length, which was 33% (TL=8.70 cm vs. Head Length=2.61cm). Another morphological character, specific to this species, is the lower jaw, which exceeds in length the upper jaw. Being a Ponto-Caspian endemite, with low population along the Bulgarian and Romanian coastline, we considered it important to point out this new record. Noting that, being known the trend of sporadic migration of this species, would not be excluded that global warming causes a shift from its normal distribution area, from northern and northeastern (Black Sea) to south-west. Therefore, future research may bring more notifications regarding this species in south-western area of the Black Sea

Correlations Between Age of Rainbow Trout (Oncorhynchus Mykiss) Female and Their Fertility Indices

From the perspective of economic efficiency and the increase of productivity and product quality in romanian trout farms, we propose to do an analysis of the impact of breeding age in rainbow trout females and its effects on fertility indices.

Morpho-Histological Peculiarities of Oro-Pharyngeal Cavity of Rainbow Trout (Oncorhynchus mykiss, Wallbaum 1792)

To conduct life phenomena, living organism made materials and energy exchange with the environment. Essentially, standing of substance and energy needs is satisfied through processes of nutrition. The digestive system of fish have some peculiarities, both in terms of shape and the presence or absence of couple anatomical segments, depending on the species diet. Oro-pharyngeal cavity represents the first segment of the digestive tract in fish (Al Abdulhadi, 2005) and its structure contains multiple items: opening mouth, oral cavity, teeth, tongue and the pharynx (Stăncioiu, 2006). Other authors (Nicolae, 2007) consider teeth and tongue as constituent elements of oral cavity, and are not considered separate units of oro-pharyngeal cavity. Whatever of this classifications, most authors agree delimiting the oro-pharyngeal cavity, above the lips, and posterior by the last pair of gill arches (Bud, 2007). Rainbow trout (Oncorhynchus mykiss, Walbaum 1792) is one of the most exploited species of culture, both in Romania and worldwide. Several studies have been made on anatomical and histological structure of the various organs and body forming apparatus, but we consider they are insufficient. In this case, the authors of this paper aim to characterize in terms, morphological and histological, the first segment of digestive system, oro-pharyngeal cavity. These studies are made reasoned, for optimization of growth and nutrition technologies and increase the economic efficiency in aquaculture. For it, must be correlated several aspects of nutrition, ensure optimal environmental conditions, anatomic and histological structure of digestive tract and circulatory, respiratory and excretory systems.
