Infection of Hysterothylacium aduncum (Namatoda: Anisakidae) in farmed rainbow trout (Oncorhynchus mykiss Walbaum, 1792)

Farmed rainbow trout (Oncorhynchus mykiss) were examined for anisakid nematodes at fish farms in Elazıg city, Turkey. A total of 439 fish (246 from fish farm ponds and 193 from net-cages) were monthly investigated in the period from February 2000 to May 2003. Only the endoparasite, hysterothylacium aduncum (Nematoda: Anisakidae) was recorded in the digestive tract of the 91 cultured rainbow trout, O. mykiss fed with...

Assessment of rural and experimental dairy products under dryland farming in Sudan

Rural dairy processing situation in western Sudan (North Kordofan) was first assessed through a structured questionnaire. Some rural dairy products were sampled and assayed for bacteriological and chemical composition. The objectives were to investigate traditional dairy products and evaluate their nutrients composition and hygienic situation. Laboratory cheese making trials were then conducted to study the effects of...

Evaluation of fuel wood marketing in Adamawa State, Nigeria

The falling of trees for fuel wood (energy) consumption cuts across most rural and urban communities in sub-Saharan Africa. However, this activity denies the existence of forest trees and wood is burnt to produce carbon dioxide which is linked to climate change. In this paper, fuel wood marketing in Adamawa State, Nigeria is evaluated. Both descriptive statistics and gross margin (GM) analysis were used to evaluate...

Molecular weights and tanning properties of tannin fractions from the Acacia mangium bark

The bark of Acacia mangium was smashed and extracted by acetone solution, and the extract was then degreased by petroleum ether. The degreased solution was extracted by diethyl ether and ethyl acetate successively. In this way, the tannin of A. mangium was divided as diethyl ether fraction, ethyl acetate fraction, and water fraction, respectively. The molecular weight of these tannins was measured by gel permeation...

Photosynthesis, ion accumulation, antioxidants activities and yield responses of different cotton genotypes to mixed salt stress

This study analyzes the effects of soil salinity on photosynthetic character, osmoregulation, content of pigment, K+/Na+ ratio, lipoxygenase and antioxidants activities in functional leaves during the flowering and boll-forming stages of two cotton cultivars, namely, CCRI-44 (salt-tolerant) and Sumian12 (salt-sensitive), grown under different soil salinity conditions. In the control plants, non-significant differences...

The study of implementation and evaluation of an alternative agricultural extension presentation system

In Taiwan, to deal with the global competitive pressure, agricultural extension improvement will play an important role. The agricultural extension workers not only need to have professional agricultural knowledge but also have good presentation skills for extension activities, especially for training courses. However, a good presentation for extension activities depended on a well-designed material. This study intends...

Response of Marantaceae and Pteridophytes potted plants for purification of formaldehyde polluted air

Ten plants from Marantaceae families and ten plants from Pteridophytes were tested for their abilities of removing formaldehyde (FDH) in the air. Each of the plants was placed in a 1.0 ×1.0 × 0.8 m glass box filled with FDH for seven days with the initial concentration as 15 mg m-3. These plants such as Neottopteris nidus cv. Volulum, Calathea lubbersiana showed the most resistant ability to FDH damage;...

An econometric approach to ascertain sorghum supply response in Zimbabwe

Despite failures of government policy to stimulate sustained growth in sorghum production in the face of increased climatic shocks on maize, there have been very little efforts to understand sorghum response to policy incentives. The main purpose of the paper was to determine how sorghum farmers responded to changes in price and non-pricing policies. The major sources of the data were the ZIMSTAT, FAOSTAT,...

Different expression of S-locus cysteine-rich protein (SCR) alleles in self-incompatible and self-compatible Brassica napus breeding lines and cultivars: Can be SCR/SP11 used as a selectable marker in breeding?

There are several approaches available for hybrid breeding in oil seed rape, Brassica napus, as cytoplasmic male sterility (CMS), genic male sterility (GMS), self-incompatibility (SI), and chemical hybridizing agens (CHA). In comparison with others, SI is regarded as one of the most valuable strategies in hybrid breeding. Unlike self-incompatible (SI) B. rapa and B. oleracea, two ancestor species, B. napus is naturally...

Biochemical and nutritional properties of baobab pulp from endemic species of Madagascar and the African mainland

The fruit of baobab (Adansonia sp.) is well known in Africa both for its medicinal properties and social uses. It is a very promising tropical fruit although it has been little investigated and exploited in Madagascar. One of the major challenges, in Africa, in the last years has been to establish the baobab as a commercial crop with an economic value. In order to know if Malagasy baobab fruits have the same potential,...
