In irder to increase natural population stocks, a sea cucumber cultivation project was attempted in the Karimunjawa Islands (Java Sea, Indonesia). Since continuous production of larvae is essential to such a project, this portion of the research focuses on methods of inducing the sea cucumber Holothuria scabra to spawn and monitoring the development of resulting larvae. Four different types of environmental manipulation were used to try and induce spawning; artificial fertilization (using manually extracted eggs and sperm), thermal shock (raising the temperature of the spawning medium), desiccation (partially drying out) and treatment with potassium chloride (KCL) solutions of various concentrations. The development of the resulting larvae was carefully observed. Results indicate that thermal shock, desiccation and potassium chloride (KCL) are all effective in stimulating the sea cucumber Holothuria nobilis to spawn. Thermal shock gave the best result with both male and female spawning and 90% larvae development. Using a stocking density of 300 larvae/ liter in 10 liter aquaria, larvae was successfully raised up to pentactula stage. Regardless of the method used to induce spawning, fertilizer eggs development into auricularia larvae at 31 hours and 30 minutes. These larvae then metamorphosed into doliolaria and pentactula larvae at day 13 and 26. Mortality of all stocks at the pentactula stage was probably due to lack of provision of settlement substance.

Significant changes in pH, both acidic and alkaline, can disrupt water quality. Furthermore, it will affect the life of aquatic biota. The purpose of this study was to determine the effect of increasing pH on heavy metal concentrations of Cu and Cd (quantitative) in shellfish bodies and on the level of damage to the gills and mantle shells (qualitative) by scanning electron microscopy. The research was conducted at the Integrated Marine Science Laboratory, UNDIP Semarang. Heavy metal analysis was carried out at Wahana Laboratorium Semarang. The scanning electron microscopy process was carried out at the Electron Microscopy Unit, Faculty of Medicine, UNAIR Surabaya. The results of the heavy metal analysis both Cu and Cd showed that pH 9 had the highest heavy metal content, namely Cu = 0.33 mg / kg while Cd = 0.57 mg / kg. Whereas for pH 7, the lowest heavy metal concentration was obtained for Cd = 0.35 mg / kg, but for the lowest Cu was found at pH 8 of 0.21 mg / kg. The differences were seen in the SEM results of gills and mantle ph 7 and 9. Observations on mantle epithelial cells and gill filaments with a magnification of 75 and 1000X showed that at pH 7 the epithelial cells had regular folds, the distance between the barriers was clear and the size was normal. Whereas at pH 9 it has irregular folds, the distance between the bulkheads is hollow and perforated. The gill filaments of pH 7 have a smooth filament structure and clear between the filaments.

Vaname shrimp is one of the most profitable export commodities in Indonesia. However, the shrimp meat undergoes rapid quality degradation when shipped without any preservatives. This is an issue since the preservatives commonly found on the market are formalin-based. This study aims to discover a natural preservative solution by utilizing microbes. The objective of the study is to discover natural preservatives made of symbiont microbe in sea cucumber's intestinal organ by antimicrobial activity screening. Sea cucumber samples were collected from Bandengan waters of Jepara. There are 3 symbiotic microbe form intestinal cucumber that can inhibit the growth from Bacillus cereus and Pseudomonas aeruginosa. These three microbes are Listeria sp., Staphylococcus sp., and Rothia sp. Consequently, tested microbial samples were prepared into a consortium microbe and were tested further as a preservative agent for shrimp with a positive control parameter (cooling). The observations conducted in this study include organoleptic properties, acidity, total colony, proximate test (protein, water, ash, fat, and carbohydrate contents), and Total Volatile Base-Nitrogen (TVBN). The results found 3 active isolates are synergic one to each other as a bacterial consortium. Acidity test of sample extract treatment measured a pH of 7.44, compared to the non-treatment result of 7.14. Organoleptic test results of the shrimp indicated that the shrimp was acceptable for consumption. Proximate test of the treatment did not show a significant difference compared to the positive control treatment. Total colony and TVBN test on treated samples resulted in 48 x 105 CFU/ml and 39.62 mgN% respectively, whereas a similar test on non-treatment sample showed 119 x 105 CFU/ml and 45.31 mgN% respectively. It was concluded that the extract of sea cucumber symbiont microbe consortium showed potency in preventing meat quality degradation in shrimp, although treatment by freezing still produces a better result.
