The study aims to determine the type of vegetation that composes mangrove forests and their zoning patterns, to know the composition of mangrove vegetation types and to determine the level of mangrove forest diversity. This study was determined based on the characteristics of the research location ranging from those close to residential areas to those located close to the beach. The method used is systematic sampling which consists of nine observation blocks and each block is divided into four circular research plots. There are 9 types of vegetation that compose mangrove forests in Wambona Village, Wakorsel District, i.e. Avicenna alba BI, Bruguiera hainnessi, Bruguiera gymnorrhiza (L.) Lamk, Ceriops tagal (Perr), Rhizophora mucronata Lamk, Rhizophora stylosa Griff, Sonneratia alba J.E. Smith, Caseolaris sonneratia (L.) Engl. and Bruguiera parviflora (Roxb.) Important Value Index (IVI) of mangrove vegetation in Wambona Village, Wakorsel District namely; 300% for tree level, pole, stake and 200% for seedling level. Diversity of mangrove vegetation types in Wambona Village, Wakorsel District as a whole is in the moderate category (moderate stability) with each tree 1.54, pole 1.57, stake 1.49 and seedling 1.64.

One of the factors that affect the growth of tiger shrimp is the quality of feed. Nutrient content in feed such as protein, carbohydrate and fat, generally used as a parameter of feed quality. Feed consumed by shrimp is not all digested, one of which depends on the enzymatic ability of the shrimp digestive tract. The use of probiotic bacteria in addition to having the ability to reduce colonies, inhibit the growth of pathogenic bacteria, and neutralize water quality, probiotic bacteria can help digestibility of the intestine. The aim of this research is to know the growth and survival of post larvae of shrimp (Penaeus monodon Fabr.) Through the provision of probiotics with different doses. The research was conducted at Balai Fish Fishing Hall of Muna Regency, Southeast Sulawesi, Indonesia. Post larva shrimp tiger (PL-20) of 120 tails, maintained for 28 days. The tested treatment was probiotic dose 5 ml (treatment A), dose 10 ml treatment B), dose 15 ml (treatment C), and without probiotics (control). Probiotics are given every 7 days on water maintenance media using a pipette (0.5-20 ml scale). Weighing results showed relatively high post-larva shrimp larvae growth of 400.00% (treatment B); 291.67% (treatment C); of 233.33% (treatment A) and equal to 58.33% (Control). Variation analysis result showed that giving of probiotic with different dose gave real effect (P<0,01) to relative growth of postlarva prawn weights (P. monodon Fabr.). Provision of probiotics has no significant effect on postlarva tiger prawn survival rate (P. monodon Fabr.). The survival rate of post larvae of tiger shrimp during the study was in the range 66.67-83.33%.
