Culture Conditions Affect The Nutritional Value Of The Copepod Acartia Tonsa, Arne M. Malzahn, Nicole Aberle-Malzahn, Katherina Schoo, Maarten Boersma

Journal of Agricultural and Marine Sciences

Live feed are still necessary for the rearing of larval stages of several fish species, especially marine ones. Compared to Artemia, copepods are of superior quality. This is based on a suite of traits like size, movement, and nutritional value. Copepods are for example usually high in protein and fatty acids. Essential fatty acid profiles reflect to a large degree the fatty acid supply, which provides the opportunity to manipulate fatty acid profiles of, amongst others, copepods. By manipulating nutrient supply of the algae Rhodomonas salina we were able to double essential fatty acid concentrations in naupliar and copepodit life …

Ashwagandha: Is It Safe? A Review Of The Clinical Evidence., Thomas Brendler, Elizabeth Williamson

Oxford ICSB

Over the last decade, ashwagandha (Withania somnifera (L.) Dunal, AS) has been brought under increasing scrutiny regarding its safety for the use in food supplements, culminating in a recent recommendation for an Article 8 procedure according to Regulation (EC) No 1925/2006 in the European Union (EU). Once executed, this could lead to a ban of the use as an ingredient in food supplements. One of the regulators’ concerns is the purported lack of clinical safety data combined with evidence for what may constitute a safe daily dose. In this overwiew we assess evidence stemming from 96 clinical trials conducted over …

A Review Of Observations Made On Select Parameters Of The Camel Immune System, Eugene H. Johnson, Khalid R. Al-Habsi, Rashid M. Al-Busaidi Apr 2025

A Review Of Observations Made On Select Parameters Of The Camel Immune System, Eugene H. Johnson, Khalid R. Al-Habsi, Rashid M. Al-Busaidi

Journal of Agricultural and Marine Sciences

Despite the camel’s long historical interaction with man there is only a limited number of studies available pertaining to the immunobiology of this species. This is unfortunate as the camel has evolved into an animal capable of not only surviving under extreme environmental conditions but also into one that is relatively resistant to a great number of infectious diseases. Accordingly, it is of interest to understand the various components operative in the camel immune system, as a potential basis of manipulating the immune response of other domesticated animals to respond to disease-causing agents in a similarly effective fashion. Recent research …

Habitat Preferences Of Juvenile Abalone (Haliotis Mariae Wood, 1828) Along The Dhofar Coast Of Oman And Implications For Conservation, Schalk Willem Petrus De Waal, Mohammed Balkhair, Ali Al-Mashikhi, Salem Khoom Apr 2025

Habitat Preferences Of Juvenile Abalone (Haliotis Mariae Wood, 1828) Along The Dhofar Coast Of Oman And Implications For Conservation, Schalk Willem Petrus De Waal, Mohammed Balkhair, Ali Al-Mashikhi, Salem Khoom

Journal of Agricultural and Marine Sciences

Surveys were conducted along the eastern Dhofar coast of Oman to investigate densities and habitat preferences of juvenile Haliotis mariae (< 3 cm SL). Average density was 0.62 m-2 (SD 0.56); average urchin density was 3.4 urchins m-2 (SD 3.9). Relationships between juvenile abalone densities and small boulders (<30 cm in diameter (Ø)) tested significant (p = 0.049), as did those between juvenile abalone and urchin densities (p = 0.031). Selectivity (w) and standardized (B) ratios quantifying the relative probability of selection by juvenile abalone for different categories of resource available were calculated. For the studied area B values tested significantly different for (p = 0.004) the different habitats, urchins, boulders <30 cm, 30> <50 cm, and >50 cm Ø, respectively. B values were highest for urchins (6 times that for small boulders), and for boulders <30 cm Ø (double that for boulders 30> <50 cm Ø). B values for boulder habitats decreased as boulder size increased. Urchin utilisation by juvenile abalone as shelter ranged between geographic areas from a minimum of 15.5% to a maximum of 47.6%. The proportion of total habitat that is preferred by more than 97% of juvenile abalone found, including urchins and boulders < 50 cm Ø, comprises 29% of surveyed substratum. While the role urchins play on wild juvenile H. mariae has not proved vital, it is definitely significant. Although juvenile densities are low and are not currently limited by the availability of suitable habitat, it is crucial to identify and conserve those microhabitats that support recruitment of H. mariae. The abundance of these areas should be among the criteria used in selecting protected conservation areas.

Old Ways In A Changing Space: The Issue Of Camel Pastoralism In Dhofar, Ali Tigani Elmahi

Journal of Agricultural and Marine Sciences

In the Arabian Peninsula, the Dhofar region is rich in camels. This national wealth has always been administered by traditional nomadic pastoral management, which must have evolved in Oman with the introduction of camels as domesticates in prehistoric times. In this region, camels have always depended on the free grazing system which is governed by tribal territoriality. Today, Dhofar is experiencing an extensive process of development. Land value has increased immensely, to the extent that it cannot be used for camel pastoralism. Furthermore, traditional camel management has always been directed to meet requirements of a subsistence economy. It has never …

Hematophagous Flies In Dhofar (Sultanate Of Oman): A Limiting Factor And A Potential Pathogenic Vector, Ali Tigani Elmahi Apr 2025

Hematophagous Flies In Dhofar (Sultanate Of Oman): A Limiting Factor And A Potential Pathogenic Vector, Ali Tigani Elmahi

Journal of Agricultural and Marine Sciences

In Dhofar, pastoralists take certain precautionary measures against hematophagous flies: Haematobia minuta Bezzi, Musca crassirostris Stein and Forcipomyia (lasiohelea) whitcombei Boorman. Through their feeding on domesticated animals, these flies impede pasturing in certain areas during the rainy season (Khareef); hence they act as a limiting ecological factor and a custodian of the flora. The possibility that these flies could be potential pathogenic vectors has not been investigated in Oman, although in other parts of the world they are recognized as carriers of disease agents. The paper draws attention to this issue in Dhofar.
