Abstract

This study aimed to examine on some properties and to draw attention to why it cannot create an intensive stock amount of Chamelea gallina (Linnaeus, 1758) in the Gulf of Antalya in the Mediterranean coast of Turkey, Levantine Sea. Specimens of C. gallina displayed total shell legths of 6 to 32 mm, mean 14.5 mm and total weights of 0.1 to 11.44 g, mean 1.82 g. The total shell length and total weight relationship of C. gallina was calculated as TW =0.3333 * TSL 2.9894 (R² =0.9850). The mean meat yield was found as 12.10±0.9264%. A small number of C. gallina samples were collected. The majority of the collected striped venus were determined as empty shell. It was observed that the razorfish (Xyrichtys novacula) were fed with C. gallina during research. Finally, these results may draw attention the reasons why this species cannot form an intensive stock amount. It is thought that the empty shells of the striped venus can be caused from feeding of the razorfish (X. novacula) with C. gallina and environmental factor changes.Keywords: Chamelea gallina; length; weight; meat yield; mediterranean

Abstract

Rumput laut merupakan sumber daya hayati yang sangat berlimpah di perairan Indonesia. Namun demikian pemanfaatannya untuk pengolahan produk pangan sangat terbatas, terutama untuk produk pangan fungsional. Rumput laut berpotensi dikembangkan sebagai produk pangan fungsional karena mengandung zat gizi dan komponen bioaktif yang berkhasiat untuk kesehatan. Rumput laut mengandung sejumlah komponen bioaktif seperti senyawa fenolik, pigmen alami, polisakarida sulfat, serat dan komponen bioaktif lainnya yang telah diteliti berkhasiat untuk kesehatan. Untuk dapat dikembangkan sebagai produk pangan fungsional, rumput laut yang digunakan harus bebas dari cemaran logam berat dan bahan pencemar lainnya, harus mengandung komponen bioaktif dan zat gizi yang tinggi sehingga harus ada penerapan standar penanaman dan penanganan pasca panen yang baik di tingkat petani rumput laut. Selain itu Proses pengolahan pangan yang diterapkan tidak merusak komponen bioaktif yang terkandung dalam rumput laut. Optimalisasi pengolahan rumput laut sebagai produk pangan fungsional merupakan alternative pemanfaatan potensi rumput laut Indonesia yang dapat meningkatkan nilai ekonomi rumput laut dan yang lebih penting dapat menyediaakan akses pangan sehat bagi masyarakat luas.Seaweed is a living resource that is abundantly available in Indonesian water. However, its utilization in food processing is very limited, especially as functional food products. Seaweed has the potential to be developed as functional food products because it has nutrient and bioactive components that are beneficial for health. Seaweed has a number of bioactive components such as phenolic compound, natural pigment, polysaccharide sulphate, fiber and other bioactive components that has been studied to be advantageous for health. For a seaweed to be developed into functional food product, it must be free from heavy metal and other pollutant contamination, and must contain bioactive components and high nutrients, thus, a good cultivation and postharvest handling standard have to be applied in seaweed farmer level. Moreover, the food processing applied should not damage the bioactive component within the seaweed. Optimization of seaweed processing into functional food product is an alternative for seaweed potential utilization in Indonesia, which could improve the economic value of the seaweed, and more importantly it could provide access for healthy food for community.
