South Pacific Islands Fisheries Development Agency to determille feasibility areas of fishery developnent in the region and to assist in formulation and implementation of specific action programmes in the various island territoriese The project became operational on 22 July 1970 and as pa.rt of the project operation, FAO assigned a Marille Biologist (Cray fish) Consultant, with the following terms of reference: "To prepare a review of the existing fisheries for rock or spi.ny lobster (crayfish) in selected territories of the south and southwest Pacific, including identification of the species concerned and compilation of available knowledge of the behaviour of ari.d methods of fishing for these organisms; to indicate areas where further stu~ and research is desirable and to prepare programmes for such investigation and prelimina;ry proposals for the ratioD&l management of the available stocks~" - - The following report is based on interviews with fishermen, private industry and Governnent officers, supplemented by visits to actual or potential rock lobster areas and an assessment of habitat by diving and by aerial su.rvey. In 1969, the South Pacific Commission (SPC) and South Pacific Islands Fisheries Develop ment Agency (SPIFDA) circulated a Spi.ny Lobster Resource SW!"Vey questiom:uaire to assist in the assessment of the identity a.nd the abundance of rock lobster in ea.eh Territory. Additional observations relative to other fisher.r developments in the Pacific have also been included in this report"' In accordance with 11pecific requests for surveys by Territories, the total survey was divided into four tours and each tour carried out by the Consultant commenced a.nd terminated at No'Wl!ea, he~erl'!i of the SPIFDA. The programme was a..-ranged as follows: Tour 1 - Fiji9 Western Samoa9 American Samoa and Tonga Tour 2 - New Guinea, Solomon Islands and New Hebrides TolU' 3 - French Polynesia and the Cook Islands Tour 4 - New Caledonia. In addition, arrangements were made for Mr., Craig McDonald, a Peace Corps Volunteer~ studying rock lobsters in the United States Trust Territory, to report to the consultent in New Guinea.. 2. FIJI 2.1 SYNOPSIS OF ACTIVITIES The Consultant landed at lifa.di 9 visited suva.9 La.utoka, Western Ya.saws., Lau Group Ongea., Fu.langa.

The two main islands and those m.aller :islands in th9 ill!eediate vicinity :::eceive miuch rain - over 5 080 mm in the central and southern pa..""tsG Only about : 800 - 2 500 ::mi fall i::z, the northern and western parts (including the Ya.sawa. Group). '!'he further offshore islands of the Lau Group also experience low rainfall, and droughts are not uncOll!llllon at Komo~ Ongea and the Fulanga Islands. Most of the islands a.re of volcanic formation and consis·~ of very high peaks, the highest being Mt. Victoria ( 1 323 Cloud haJ:lgs almost permanently over these regions and rainfall is reg..tlar, resulting in many rivers draii::ting off to the coast :forming river deltas of an estuarine nature which are subject to the rise and fall of tide - about 1.5 m (1.8 m during the spring season)o The non-volcanic atolls and calcareous islands are 18ainly in the Lau Group which a...""'El US'.:tally low, about 79 m11 and receive li'o;'r,le rainw villages often suffer ';;,"ater shortages in these area.so 2o3 COASTAL FEATURES lUID ZONES The high rainfall, volcanic islands have ma:ng::roves at the water's e~., Due to fresh w"ater run off and silt content in these areas 11 coral growth is limited and there are lagoons inside the hard coralline barrier reefs some dista:.n.ce offshore o The low rainfall atolls, c~s and limestone islands have coral growth 11112ch closer to -!;he island. There is generally a coral reef platform close to the shore and a coralline algae hard outer reef on the side exposed to the major swell (generally southerly (SE.))o Where seepage through the limestone is regula.r11 e"g" off Fulanga beach.1 shallow sea grass beds a.re maintained behind the barrier reef., In other places seepage near river mouths (eogo Komo) forms beach rook by oementation of beach sandsc · Reports 11 discussions and personal obse:rration support the contention that in Fiji four species of Panulirus are present. Po renioilla:tus., These were caught mainly on the south east sides of islands on the exposed coralline algal reef e~§' living &"'!longst the surf a.lld in the surge chaJmels.
