Abstract

Nutritional quality of lupin based shrimp (Penaeus monodon) aquaculture feeds was evaluated in terms of pellet water stability. Two series of water stability experiments were carried out to study the effects of lupin meal inclusions as an dietary protein alternative for fish meal (Experiment 1) and soybean meal (Experiment 2) on percentage dry matter and protein leachings of the compounded test diets.  Increasing the replacement levels of dietary fish meal with lupin meal resulted in significant decrease (P<0.05) of pellet water stability over the 480-minute immersion period. A significant improvement in water stability with the increase of the soybean meal replacement levels with lupin meal up to 50% was found, however, further increase above 50% substitution level resulted in reduced water stability of the diets. It is  concluded that lupin meal can not totally replace either fish meal or soybean meal in shrimp formulated diets and a 50% replacement level of dietary fish meal or dietary soybean meal with lupin gives a promising good result in terms of pellet water stability for P. monodon diets.

Abstract

A screening among 4"C-culturable isolates obtainedfom dcep~sea water of Nankai Trough from a depth of approximately 4,000 m resulted in a total of 5 psychrophilic bacteria showing no growth at 20° C. Phylogenetic characterization based on l6S ribosomal DNA sequence analysis showed that the isolates belonged to the genus Colwellia, Moritella, and CNPT-3, which could be assigned to Psychromonas.

Abstract

Tourism is a multi-discqalinary activitjy that touches almost every aspect of human endeavor. In view of its international character and its role in the development of the national economy, an attempt has been made to study the economic, socio-cultural and environmental impact of tourism on regional development in developing countries such as the Philippines. Tourism development is an economic and industrial activity involving many individuals, firms, corporations, organizations and associations. It is economically important as it provides a source of income and employment, brings in infra-structural improvements and helps in regional development. (Negi, 1990) For a province such as Guimaras Island tourism development is a powerful tool needed in ‘ solving sonic of the provincial problems. Furthermore, in some cases, it contributes to the national economy by developing and revitalizing the economic condition more quickhi than other industries. Many sectors ofthe community benefitjrom the injection of additional wealth that tourism brings

Abstract

This experiments was conducted as response to the serious negative impact of shrimp aquacultres into the environment. The shrimp-Gracillaria polyculture system was hypothesized to reduce excess pollutant in the shrimp pond. Variation in Gracillaria density was used as treatments. Two important aspects are discussed in this paper, that are the effect on shrimp productivity and efficiency in carbon energy conversion into harvestable products. There were significant evidences that the shrimp-Gracllaria polyculture system increase the sizes, total biomass, survival and growth rate of shrimp. The density of Gracillaria was positively correlated with all of those parameters. The carbon energy conversion was also significantly affected by Gracillaria density. The carbon energy conversion into harvestable products was more efficient if Gracillaria density was increased.

Abstract

A wave runrup height on a coastal structure with sloping face is one ofthe considerations in the planning and design of sea—walLs or brealcwaters. In this paper, a wave run—up height on rock slopes of a coastal structure is presented using the empirical approach based on incident waves entering coastal structure. A height and increasing level of wave run-up hom incident wave amplitude are presented on rock slopes of a coastal structure with various angle of structure slopes and various water depths. The influence of incident wave height and wave period on the wave run-up height are described through the correlation analysis, and the probability distribution of wave run-up height is described as a Weibull distribution.

Abstract

Milkfish brackishwater pond (tambak bandeng) in “Sumbersari” can be divided into three types: (a) fry pond; (b) brackishwater pond type 1; and (c) brackishwater pond type 2. Milkfish brackishwater pond cultivation is profitable, especially when the area is large. The idea of cultivating giant tiger shrimp (udang bago) in the brackishwater pond by using a mixed (campuran) method appears to generate considerable additional income for those who practiced it.
