The purpose of this study was to determine the yield and type of catch, the comparison of the number of catches and the efforts to manage electronic FADs on Gill Net fishing gear. This research was conducted in Bulukumba waters from February to March 2017. Data collection was carried out by direct observation of fishermen in Bulukumba waters. The samples used in this study were FADs installed by fishermen in the waters of Bulukumba as many as 20 locations. Based on the research results, fish catches with electronic FADs ranged from 98 to 131 fish per fishing trip with a total catch of 2,324 fish. Meanwhile, the usual FAD catches ranged from 51 to 84 fish per fishing trip with a total catch of 1,313 fish and the highest type of fish was selar, followed by male mackerel, Selar bentong, white Kuwe, Layang, Barracuda, selangat and Mata goyang. The ratio between the catch and the use of electronic FADs was 64%, while the regular FADs were 36%. Considering that FADs are an effective tool in collecting fish, a sustainable management strategy is needed, including by (1) community based management, (2) limiting fishing efforts, (3) stopping the addition of shallow marine FADs. , (4) use of fishing gear with large mesh sizes and (5) prioritize the use of deep sea FADs.

Abstract Kasa island, with an area of 52.80 Ha, was declared a KBA in the Wallacea region with the staut of wildlife sanctuary and Ocean Tourist Reserve because of its particular biodiversity and its service to the environment. This research aimed to determine the social, biophysical potential and the threats to the region, as well as to explore a collaborative management. The methods used included survey, spatial analysis of the vegetation and Focus Discussion Groups (FDG). The results showed a variety index level of 1.37%. The dominant tree species were belo hitam, salamuli daun besar and kayu besi pantai. The belo hitam species had the highest INP. The wildlife sanctuary is the habitat of the Gosong Maluku bird (Eulipoa and Megapodis), an endemic species called Gosong Maluku (Euliopa wallacei). Other species include Gosong Kelam (megapodius freycinet). The coastline with its white sand and natural ocean is a tourist attraction with development potential. The strategy which needs to be developed is by using strengths to take advantage of opportunities so they can overcome weaknesses and threats. the strategies developed are as follows: Collaborative Management; Strengthening The Capacity of Local Community and Formulation of regional policy regarding Kasa Island management

The sustainable management of BNR biosolids requires a holistic approach which integrates BNR liquid treatment processes, on-site sludge handling processes and off-site biosolids reuse/disposal. A market focussed biosolids reuse/disposal strategy is a key element of the sustainable management of BNR biosolids. A methodology for preparing a biosolids management strategy is presented. BNR biosolids has a number of characteristics which affect biosolids management. These include: potential for mutrient release, dewaterability, and the need for biosolids stabilisation. Current practices for sludge handling and stabilisation in Australian BNR plants are also discussed.

The use of partially resistant cultivars should become an essential component of a sustainable management strategy of potato late blight, caused by Phytophthora infestans. It is therefore important to determine to what extent P. infestans populations can be selected for increased aggressiveness by potato cultivars with different levels of partial resistance. To this end, we sampled P. infestans populations from France and Morocco, chosen as locations where late blight occurs regularly but which differ in the distribution of potato cultivars. Cross-inoculation experiments were used to determine the aggressiveness of all populations to potato cvs. Bintje (prevalent in France but not grown in Morocco) and Désirée (popular in Morocco but cultivated to a very small extent in France). French populations were more aggressive on cv. Bintje than on cv. Désirée, irrespective of the site they were sampled from. Their aggressiveness increased between early and late samplings, suggesting that both cultivars selected for increased aggressiveness during epidemics. By contrast, Moroccan populations were more aggressive on Désirée, regarded as partially resistant in Europe, than on Bintje, highly susceptible under European conditions. These data indicate that P. infestans populations adapt to locally dominant cultivars, irrespective of their resistance levels, and can therefore overcome polygenic, partial resistance. This adaptive pattern may render partial resistance nondurable if not properly managed.
