1. Evaluation of indigenous molluscicides in water against schistosomiasis vectors - Makanga, B.; Monkiedge, A.; Obbo, C.J.
Seven varieties of indigenous Phytolacca dodecwulra L'Herrit (Phytolaccaceae) were field-tried for molluscicidal potency. Varieties (U96) and (U95) collected from Kabarole and Kabale respectively were the most potent with LD90 equal to 2.54 and 6.46 mg.t-· respectively. Water bodies ranging between 4,770 and 347,510 Iitres in Kibimba rice fields were treated with up to 50mg.t-· Snails kills were monitored every three months and 92 - 100% mortality rates were realized. HPLC fingerprints revealed the two P. dodecandra varieties to contain highest concentration of the active principle, oleanoglycotoxin- A or lemmatoxin - A.

2. Marine Vertebrates and Low Frequency Sound: Technical Report for LFA EIS - Croll, Donald A.; Tershy, Bernie R.; Acevedo, Alejandro; Levin, Phil
Over the past 50 years, economic and technological developments have dramatically increased the human contribution to ambient noise in the ocean. The dominant frequencies of most human-made noise in the ocean is in the low-frequency range (defined as sound energy below 1000Hz), and low-frequency sound (LFS) may travel great distances in the ocean due to the unique propagation characteristics of the deep ocean (Munk et al. 1989). For example, in the Northern Hemisphere oceans low-frequency ambient noise levels have increased by as much as 10 dB during the period from 1950 to 1975 (Urick 1986; review by NRC 1994). Shipping...

3. Survey of veterinery [sic] drug residues, environmental contaminants and mycotoxins of cultured shirmp [sic] in Iran - Motalebi Moghanjoughi, Abbasali
Economical achievement of optimal growth in developing countries may lead to sustainable poverty reduction. Agricultural activities play an important role in economy and human being welfare, which leads to establishment of food security and quality. Aquaculture products in developing countries share 51.4 percent of total agricultural production.7—percent in developed countries. Therefore undoutedly food production by means of quality and quantity has to be increased .The history of shirmp production goes back to 500 years ago. Today 50 countries of the world produce shirmp .In Islamic Republic of Iran shrimp production started since 1992 in the coastal region of Persian Gulf....

4. Food safety through HACCP - Adan, R. I. Y.

5. Epidemiology of bilharzia (Schistosomiasis) among fishing communities of Lake Victoria - Kadama, A.B.; Magumba, K.M.; Balirwa, J.S.; Kyangwa, I.J.; Odongkara, K.
The study was done in six districts of Mukono, Jinja, Iganga, Bugiri, Busia and Kalangala. At both mainland shoreline and islands, 271 adult respondents were randomly selected from 17 landing sites of Lake Victoria over a four months period between October 2000 and January 2001. A questionnaire was administered for symptoms of schistosomiasis and samples of stool, urine and blood were taken from respondents. Stool and urine were analysed for schistosome eggs and blood. Blood was analysed for increased eosinophils. Snail samples were collected from various depths along the shoreline of study sites identified and screened for schistosome cercariae.

6. Facing the challenges in aquaculture through biotechnology - Ayson, Felix G.

7. Polymerase chain reaction (PCR) in disease diagnosis - de la Pena, Leobert D.

8. Fish health: What is a diagnosis?

9. Isolatin [sic] the bacteria produced biactive [sic] metabolits [sic] cytotoxic compound in order to prduction [sic] anticancer substance in the coral regin [sic] the Persian Gulf (Larak Island) - Safaeian, Shila
In the present investigation the marine bacteria isolated from corals, sponges sea water and sediments of coral regions in the larak Island located in the Persian Gulf and were examined for ability to produce cytotoxic metabolits in order to use as an anticancer compounds. Cytotoxic effect were isolated bacteria from different samples and were examined by Artemia Cytotoxic Bioassay test, in which 4.5 percent of sea waters, 12 percent of sediments and 28 percent of marine invertebrat showed cytotoxic activity, using Brine Shrimp Bioassay test. Streptomyces S-2004 isolated from soft coral specified as Sinularia erecta had LC50=0.5mg/m1 in Brine Shrimp...

10. Future drugs from the sea
The article presents several marine chemicals that are likely candidates for future drugs. There sources and applications were also discussed.

11. Nereistoxin
The article discusses Nereistoxin, a toxin isolated from marine annelids, its pharmacological and agricultural applications are discussed in the article.

12. Toxicity test: Sponge toxin on tilapia fry
The research was conducted to determine the toxicity of extracts from five Philippine species of marine sponges on tilapia Oreochromis niloticus fry. It was found out that the most potent was the methanol extract of Dysidea herbacea, it kills with the least toxin and at the shortest time.

13. Folk medicine and horticulture
The article discusses the uses of marine organisms in folk medicine and in horticulture in the Philippines. Commonly used marine organisms are the different varieties of seaweeds, sea urchin, sea cucumber, turtle, crocodile and fishes such as grouper and rabbitfish.

16. Recommendations on the effects of aquaculture on public health
The paper presents some recommendations on the effects of aquaculture on all persons affected by and involved in aquaculture, and to other users of waters in [which] aquatic organisms are farmed or which are affected by aquaculture: the farm workers, handlers and processors, sellers and consumers of aquaculture products.

17. Adopt sustainable development principle in aquaculture
The inadequate planning and inefficient management of coastal aquaculture has resulted into serious socioeconomic consequences. These are the displacement of rural communities which traditionally depended on mangroves due to large-scale mangrove conversion for shrimp and fish farming, land subsidence caused by excessive pumping of groundwater for use in aquaculture, financial losses due to disease outbreaks, and public health consequences due to red tide. In order to maximize the socioeconomic benefits of coastal aquaculture the adoption of the principles of sustainable development is recommended. Sustainable development is the management and conservation of natural resource base and the orientation of technological and...

18. Indigenous traditional technical knowledge of disease cure and prevention through fish consumption - Pandey, B.N.; Singh, R.; Kumar, D.; Pandey, P.N.
Our knowledge regarding ethno-medico zoology is scanty and scattered. The present work is an endeavour to collect information on indigenous traditional knowledge (ITK) of disease cure through fish consumption, prepare a consolidated report on this aspect and to document our ITK so that in the long run after due verification (by Medical experts), such ITK can be patented. We also suggest for the recognition of the age old tribal medicine and establishment of a national research institute for tribal medicines at suitable place for the welfare of all the human beings.

19. Cloning and expression of zebra fish ferroportin and investigating its influence on anemia - Rafiee, Aras
Iron is required for many microbes and pathogens for their survival and proliferation including Leishmania which cause leishmaniasis. Leishmaniasis is an increasingly serious infectious disease with a wide spectrum of clinical manifestations. These range from localized cutaneous leishmaniasis (CL) lesions to a lethal visceral form. Certain strains such as BALB/c mice fail to control L. major infection and develop progressive lesions and systemic disease. These mice are thought to be a model of non-healing forms of the human disease such as kala-azar or diffuse cutaneous leishmaniasis. Progression of disease in BALB/c mice has been associated with the anemia, in last days...

20. The zonation of soft-bottom sediments in Gorgan Bay (Caspian Sea) using macrobenthos as indicator of ecological health - Ghorbanzadeh Zaferani, Seyed Ghasem
In this study, in order to assess the ecological health status and zoning of soft bottom of Gorgan Bay, the spatial and temporal distribution of macrofauna and their relationship with environmental stress were investigated. Sediment samples were collected using a Van Veen grab at 22 sampling points, seasonally during 2012-2013. The averages (±SD) of the percentages of sand, silt, clay and TOM (Total Organic Matter) in the sediment samples were determined (44.4± 15, 53.4 ± 14, and 2.2 ±2.2 and 7.2% ± 1.6, respectively). Our results showed that mean (range) of Al, As, Cu, Fe, Ni, Pb and Zn in...
