A Review of the Aquatic Environmental Fate of Triclopyr and its Major Metabolites

The purpose of this paper is to provide an overview of the aquatic environmental fate of triclopyr and its major metabolites, TCP and TMP. This review is primarily based on results of laboratory and field studies conducted by various Federal Agencies and the registrant to support the US aquatic registration for triclopyr TEA.

Framework for a pro-poor regional strategy on sustainable aquatic resources management in Asia-Pacific: a statement of understanding and recommendations

This statement was prepared by the participants of the FAO/NACA-STREAM Workshop on Aquatic Resources and Livelihoods: Connecting Policy and People, 17-19 March 2005, in Los Baños, Laguna, Philippines. This was the concluding event of the FAO Technical Cooperation Program (TCP) project entitled “Assistance in Poverty Alleviation through Improved Aquatic Resources Management in Asia-Pacific.” The purpose of the workshop was to review and share experiences of the NACA-STREAM Initiative, build consensus on the value of livelihoods approaches in aquatic resources management and poverty alleviation, and identify ways of promoting livelihoods approaches throughout the region.

Pesca experimental de corrico na zona sul da costa de Mocambique

Based on the proven existence of large pelagic fish resources in the southern coast of Mozambique, an experimental fishing trolling program has been designed to study the possibility of resources exploitation through the introduction of trolling technique on artisanal vessels (Project FAO/TCP/MOZ/5653). Although operational problems occurred, the program carried out during the year 1957, provided a collection of data and knowledge. It allowed the preparation of present paper, which could serve as an indicator for a possible implementation of this fishing method in the Mozambican artisanal sector. Sharing this study, the author expects to give a further contribution to the development of a greater pelagic fishery in the waters of Mozambique.

Two genera and species of Isopoda new to the fauna of the northern Arabian Sea

The paper is based on the new records of two genera - Lanocira Hansen and Paranthura Bate and Westwood and species L. gardineri Stebbing and P. latipes Barnard from the rocky intertidal zone of Karachi coast. Synonymes, diagnoses and geographical distribution of the genera are given. A list of known species of the genus Lanocira is provided. Both the species are described and illustrated in detail.

Effect of zinc and manganese supplementation to tricalcium phosphate rich diet for tiger puffer (Takifugu rubripes)

Effects of zinc (Zn) and manganese (Mn) supplementation to a tricalcium phosphate (TCP) rich diet for tiger puffer have been investigated. A TCP supplement to the diet decreased the growth of fish compared to the control diet with a Ca supplementation from Ca-lactate. However, addition of either Zn or Mn to the TCP supplemented diet could not improve the growth of tiger puffer. Addition of both zinc and manganese to the TCP supplemented diet improved the growth of tiger puffer.

The study of artificial propagation efficiency and fingerlings production of Coregonus lavaretus

In order to study of the artificial propagation efficiency in white fish (Coregonus lavaretus) and its fingerlings producing in IRAN, a 9 mounts study project was been done which during it, the characteristics of the matures and brood stocks fishes, the condition of their natural and artificial propagation, and the characteristics of produced frys, were been studied. Throughout the total 82 pieces caught fishes during September til February 2003, 10 pieces of them were the female brood stocks which during the catch time did not have spouse. The study of these fishes showed that there was no significant correlation between their weight and their length. The most and the least absolute fecundity of these brood stocks were 19120 and 11496 respectively. The artificial propagation was been done by 5 males and 4 females broods took which 57602 ova, with 89/2% fertilization rate, earned from them. The incubation period prolonged 55 days in 8°c. At the end of the incubation, 23913 larvae released. So the artificial propagation efficiency was calculated 41/51% in this study. Yolk sack absorption prolonged 4 days. 3 different food treatment were considered for fry breeding which contain of Brachiouns plicatilis as live food, salmon starter food as commercial food, and the mixed of equal amounts of live and commercial foods as third treatment. For each treatment, 3 repeat has been considered. Breeding duration prolonged 13 weeks throughout this period, different characteristics of fry were been studied weekly. The breeding results showed that there was very significant correlation between the weight and the length of frys. However the live food provided better results in growth and survival rate of frys during breeding initial 6 weeks. More ever, commercial food, in some characteristics, provided more acceptable results in comparing the live food after sixth week. The results of this study project showed that the artificial propagation in whitefish is possible in IRAN and the producing of its frys in order to restocking or introducing this species to the other Iranian suitable water resources is executable. Based on the earned information from this study, the suitable time for natural spawning of whitefish in IRAN (Amirkabir dam lake) determined between 10th January til 20th February.
