Rebuilding coastal fisheries livelihoods after the Tsunami: key lessons from past experience

Fishing communities around the Indian Ocean were severely affected by the December 2004 tsunamis. Programs for rebuilding coastal fisheries livelihoods need to address the pre-tsunami situation that was characterized by overfishing and degraded natural resources. Adopting appropriate strategies to ensure sustainable livelihoods will require community involvement, as well as cross-sectoral, integrated planning and management at ascending government levels. Key recommendations from the WorldFish Center study Sustainable Management of Coastal Fish Stocks in Asia are presented to encourage discussion and debate.

A compiled key to the recent Stomatopoda of the Indo-West Pacific region

A taxonomic key is presented of the Stomatopoda (family Gonodactylidae) of the IndoWest Pacific Region.

A compiled key to the recent Stomatopoda of the Indo-West Pacific region

An identification key is given for the Stomatopod family Lysiosquillidae occurring in the Indo-West Pacific region.

An illustrated key to the Malacostraca (Crustacea) of the northern Arabian Sea. Part 1: Introduction

The key deals with the Malacostraca from the northern Arabian Sea (22 degree 09'N to 10 degree N and 50 degree E to 76 degree E). It is compiled from the specimens available to us and those which are in the literature. An introduction to the class Malacostraca and key to the identification of subclasses, superorders and orders is given. Al the key characters are illustrated. Original references with later changes are mentioned. The key will be published in parts not necessarily in chronological order.

An illustrated key to the Malacostraca (Crustacea) of the northern Arabian Sea. Part 2: Stomatopoda

The key deals with 40 stomatopod species belonging to 17 genera and 9 families. Each species is accompanied by illustrations of the key characters. For each species the first reporter is referenced. A schematic diagram is given explaining terminology.

Fishes of Ceylon: a catalogue, key and bibliography

A knowledge of the specific composition of Ceylon fish fauna is essential to any programme of development of commercial fisheries, or the study of Ceylon's ichthyology and the need for cataloguing it has been keenly felt for many years. The need for cataloguing the whole of Ceylon's flora and fauna was stressed by the Natural Science Section of the Ceylon Association for the Advancement of Science during its 1952 annual sessions and it was then that the writer agreed to help satisfy this need by compiling an up-to-date check list of species of two families of fishes, the Clupeidae and the Carangidae, which are important in the beach seine fishery which he was studying at that time. In the course of this work it was decided to expand the check-list to make it comprehensive of all species of fish that have been recorded from Ceylon to date and to supply keys for their identification. This has involved a screening of the pioneer works of Bennet (1834) and Day (1878-1889) and the many subsequent references to Ceylon fish scattered through various scientific journals and other publications, some of them long out and now almost unobtainable.

Some key concepts in fisheries research and management, with emphasis on Mozambique

Some basic concepts of fishery economics and management, and fish population dynamics are recalled, as presented during a course held at the Instituto de Investigaçāo Pesqueira from 23 February to 15 March 1988 in Maputo, Mozambique. Also, some basic elements of length-based stock assessment are reviewed, with emphasis on their implementation through the “Compleat Elefan" package, used extensively during this course, when the participants analyzed their data and wrote first draft of manuscripts incorporating the results of these analyses. Some problems relative to sampling and to seasonal growth oscillations are discussed with special reference to conditions in Mozambique.

Restricted water exchange in the Negombo Lagoon on the west coast of Sri Lanka

Salinity, fresh water and sea level data from the Negombo Lagoon with respect to oceanic sea level and salinity data were considered. The open ocean spring tidal range was 0.57 m, whereas the neap tidal range was 0.10 m. In lagoon, the corresponding spring tidal range was 0.13 m and neap tidal range is 0.05 m. The lagoon tide was strongly choked because of the restricted inlet channel, through which only a limited water exchange could take place over a tidal cycle. Mean water exchange and the residence times for variable fresh water supplies were calculated. These calculations were based on fortnightly measurements of salinity and river discharges in 1993. During this year, salinity varied from 30-5‰ depending on the river inputs which were 20-225 m³ sˉ¹. Corresponding residence times varied from 11-2 days and the tide is dominated the exchange during low discharges of freshwater.
