The EC Water Framework Directive and monitoring lakes in the Republic of Ireland

The authors of the article explore and discuss the effects of implementing the EC Water Framework Directive (WFD) in the Republic of Ireland. They also summarise some of the findings from a survey of 31 lakes sampled regularly between March 1996 and December 1997. The lakes were sampled regularly for a range of physico-chemical and biotic variables that probably would be important for monitoring programmes implemented under the WFD. The authors discuss problems of monitoring lake types with varying seasonal patterns.

An account of fisheries development in the Republic of Djibouti with notes on the growth and mortality of three species of groupers

A brief description of fisheries development in Djibouti is given, with emphasis on the major constraints that have to date limited the increase of fishing effort. Estimates of L sub( infinity ) obtained through Wetherall plots are presented for three important demersal species caught off northern Somalia and landed in Djibouti: the groupers Cephalopholis sonnerati, Epinephelus chlorostigma and E. areolatus (Fam. Serranidae). These are combined with estimates of the growth performance index O' to calculate K values, subsequently used for the construction of length-converted catch curves. The estimate of mortality thus obtained suggests that these stocks are lightly fished.

A comparative note on the modus operandii of reservoir development in Republic of China and India

Principles adopted by China for the development of reservoir fisheries are discussed. Production of some of reservoirs of China with that of India is compared. The reasons for obtaining higher production in China have been recognised as: emphasis on utilization of all resources for food production; direct feeding; use of selected varieties of fast growing carps; keeping 15 pigs per hectare of water area for application of pig void and application of manure; production of fingerlings at the reservoir sites enclaving coves and bays; grading and removing obstructions from bottom; rational harvesting and stocking and improvement of reservoir shore areas as a whole. Some of these measures which could be implemented in Indian conditions are briefly described.

Invertebrate communitites of lakes Mutanda, Mulehe, Kayumbu and Chahafi and their role in fishery production

Kisoro is a small district (734 km2 ) located in the highland areas of south western Uganda; bordering with Rwanda in the south, Democratic Republic of Congo in the west and Kabale District in the north and the east. The district contains four medium- to- small lakes namely: Mutanda (26.4 km2 ), Mulehe (4.1 km\ Kayumbu (2.2 km2) and Chahafi 1.0 km2). These lakes support small subsistence fisheries for a largely agricultural local population. They are, therefore, locally important as a source of animal (fish) protein, income and employment to the riparian human communities. The fish species include tilapiine fishes: Oreochromis niloticus, 0. leucostictus, Tilapia zillii; Clarias carsoni (Nsonzi), Barbus spp, Cyprinus carpio (Common carp) and the red shrimps

Developments in transgenic fish in the people's Republic of China

In the People's Republic of China, genetically modified (GM) fish are being developed primarily to produce desirable alterations to growth rates or feed-conversion efficiency. Up to the present, no transgenic fish have been commercially approved for human consumption. This review introduces advances in the People's Republic of China in transgenic fish studies, biosafety studies of fast-growth GM fish, and the regulation of GM fish.

A new genus and species of freshwater monostiliferous hoplonemertean (Nemertea, Enopla) from the People's Republic of China

A new genus and species of freshwater monostiliferous hoplonemertean, Limnemertes poyangensis gen. et sp. nov., from Poyang Lake, People's Republic of China, is described and illustrated. The taxon is compared and contrasted with previously described freshwater hoplonemerteans. This is the fourth species of freshwater nemertean to be described from China and the first recorded from Poyang Lake.

Records of enchytraeidae (Clitellata) from the People's Republic of China

Eleven species of terrestrial and aquatic Enchytraeidae are reported from southeastern China. Fridericia multisegmentata and Enchytraeus athecatus are new to science, while most of the others are recorded from the country for the first time.
