Abstract. Expensive protein source which mainly fish meal, experience decrease of supply from fishery
resources. Aquaculture is facing great decline in production if sustainable sources cannot be found to
lace fish meal. Apple snail (Pomacea spp) is invasive pests that now pose serious damage to rice
growers in Malaysia which was brought into the country around the early 1990's. It has been able to
adapt in Malaysia because there are no natural enemies able to prey them, also fast and quick
reproduction. Despite the damage brought by apple snail, the protein content can be up to 50%. Typical
diets for fish should contain from 32% to 45% of total protein content. Due to that, it can be a good
replacement to fish meal. This study has been conducted by producing a dry pellet with apple snail,
palm oil and flour as raw ingredient. The objective was to satisfy the fish diet by providing this new
protein source. The experimental design involves Clarias gariepinus fingerling fed on apple snail pellet
compared with commercial diet. Result shows that, there is no significant different in average of
C.gariepinus weight gain which were 2.67g in GOWEM pellet whereas commercial diet was 2.88 during
8 weeks of experiment. There was also, no significant difference in food conversion ratio (FCR),
(P.0>05) in the mean weight gain specific growth rate (SGR) and survival rate. Thus proved that apple
snail can be utilize as protein source in aqua feed.

Key Words: Apple snail (Pomacae sp.), Protein substitute in fish pellet, Invasive species,
C.gariepinus fingerlings.

Abstract. This study examines the reaction of Sea cucumber, Stichopus horrens and Aloe Vera,
Aloe barbadensis miller mixed gel on the external wound healing of animal. Sea cucumber or as well
known as Gamat in Malaysia, is one of the Holothurians that lives in marine habitat and has been widely
used by various industries such as pharmacy, cosmetics and others. The sea cucumber is reported to
have rich amount of glycine, arginine and has about 70% collagen. Hence, it has been used traditionally
to treat wound. Along with the Sea cucumber, Aloe Vera, is another one of the natural remedies that
rich in various nutrients that have been used traditionally to soothed the wound besides to promote scars
healing and else. In this study, we used both the natural ingredients to promote external wound
treatment and scars healing of the Albino mice, Rattus norvegicus. The objective of this study was to
produce a product of mixed gel containing Sea cucumber and Aloe Vera, to determine the chemical
content in the gel produced and lastly to study the effect of the gel on external wounds of Albino
laboratory mice. Gel sample have been analysed to laboratory for detection of potential hazardous
component. The result shows promising effect which takes short time to heal and does not leave scarring
on Albino's external wounds. Therefore, this formula could have a great potential to be marketed
however, some further study of suitability on different skin type, allergen reaction, the stability and expire
should be done first. Keywords: Sea cucumber; Stichopus horrens; Aloe Vera; Aloe barbadensis miller;
gamat gel; Wound healing; natura;, aqua cosmetic.
