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.

The northern Arabian Sea Isopod fauna is keyed out, excluding the gulfs fauna. Some terrestrial species are also included. Previous accounts and recent collections from Pakistan mainly at Karachi have turned up 7 suborders, 18 families, 76 genera and 12 1 species. There 5 are new records from Pakistan. For each species, there is an illustration and information of its reporter from the area and on its host, if parastic. The source of illustration is also given.
An illustrated key to the Malacostraca (Crustacea) of the northern Arabian Sea. Part 3: Euphausiacea

The key includes twenty-one species of euphausiids belonging to two families and six genera. The key was prepared following Brinton (1975). Since several authors attributed a fundamental importance to thelycum in systematics of euphausiids therefore the available figures of thelycum are also included.

Rubrifloradilactone C (4), a novel bioactive nortriterpenoid, along with four other nortriterpenoids (1-3, 5) were isolated from Schisandra rubriflora. The structure of 4 was determined by extensive NMR spectral analysis, computational evidence by using t

The key deals with the Decapoda, Anomura of the northern Arabian Sea, belonging to 3 super-families, 10 families, 32 genera and 104 species. With few exceptions, each species is accompanied by illustrations of taxonomic importance; its first reporter is referenced, supplemented by a subsequent record from the area. Necessary schematic diagrams explaining terminologies are also included.

Three species of caligid copepods (Siphonostomatoida) belonging to genus Hermilius Heller, 1865 were recovered from the giant marine catfish, Arius thalassinus Ruppell, taken from the Persian Gulf. They are H. pyriventris Heller, 1865; H. longicaudus n. sp.; and H. longicornis Bassett-Smith, 1898. H helleri Pillai, 1963 is proposed to be relegated to the synonym of H pyriventris. A key to the eight species of Hermilius is provided.

Socio-economic Monitoring (SocMon) is an approach and set of tools for conducting socio-economic monitoring of changes in coastal communities. Key considerations included: importance of local partnerships; government and civil society partnerships; emphasis of adapting SocMon to local needs and priorities; capacity building; engaging with local stakeholders; inter and intra-regional collaboration; importance of language; and importance of language.

The paper provides key for the identification of the East African marine fishes. Just like in most determination keys this one is based on the "either-or" principle, i.e. there is a single alternatIve at each point. A specimen either fits all the characters recorded, or fails to conform to one or more characters and you should then proceed to the next number, keeping this up until the fish to be identified does fit all the characters.
