The blood clam, Tegillarca granosa (Linnaeus, 1758) is one of the economically important aquatic organisms. Therefore, information related to biometric conditions is crucial as preventive and responsive efforts to manage blood clams. This study aims to analyze the biometric condition of blood clams collected from the northern coast of Banda Aceh City. Blood-clam samples were collected from three locations, namely Alue Naga, Tibang, and Deah Raya. A total of 300 blood clams were observed. The biometric parameters included the distribution of length and weight classes, the relationship between length and weight, condition factors, ratios, and correlations between total weight, meat weight, and shell weight were measured. The results showed that the majority of blood clams found in Deah Raya were in the smaller length and weight classes (30-32 mm and 12,25-17,24 g) compared to those found in Alue Naga (33-35 mm and 17,25-22,24 g) and Tibang (42-44 mm and 22,25-27,24 g). Despite having identical growth patterns (negative allometric) and condition-factor values, the blood clams collected from Alue Naga had higher meat weight ratios than those collected from the other two locations. The correlation values between the weight of the meat and the total weight of the blood clams collected from Deah Raya tends to be lower than those of blood clams obtained from Alue Naga and Tibang, which are 0,55; 0,81; and 0,78, respectively. Keywords: biometric, environmental factor, Deah Raya

Sperm cryopreservation is one of the methods in preserving germplasm and avoid the extinction of native fish. The success of this technique requires proper use of protocol because each species needs a different response to certain protocols. However, very limited of works have been done in Indonesian fish; Presently, there were only 9 species of freshwater, namely; Channa striata, Chromobotia macracanthus, Barbonymus gonionotus, Mystus nemurus, Osphronemus goramy, Osteochilus hasseltii atau Osteochilus vittatus, Poropontius tawarensis, Rasbora tawarensis, and Tor soro, and one species marine fish Ephinephelus lanceolatus have been successfully developed the cryopreservation protocols. The objective of this review paper is to summarized and evaluate the best protocol for sperm cryopreservation of above species The reviewed aspects are including the type of extender and cryoprotectant, freezing process (storage time and temperature), thawing (thawing time and temperature) and observations (including the percentage of motility, viability, abnormality, fertility, and hatching rate). Keywords: Extender, Cryoprotectant, Freezing, Thawing ABSTRAKKriopreservasi sperma adalah salah satu cara untuk melestarikan plasma nutfah Indonesia sehingga dapat terhindar dari kepunahan. Keberhasilan kriopreservasi sangat tergantung pada protokol yang digunakan, karena setiap spesies memiliki respon yang berbeda terhadap protokol tertentu. Namun sayangnya sangat sedikit penelitian terkait kriopreservasi sperma ikan-ikan asli Indonesia. Sampai saat ini hanya 9 spesies ikan air tawar (Channa striata, Chromobotia macracanthus, Barbonymus gonionotus, Mystus nemurus, Osphronemus goramy, Osteochilus hasseltii atau Osteochilus vittatus, Poropontius tawarensis, Rasbora tawarensis, dan Tor soro) dan satu spesies ikan laut Ephinephelus lanceolatus yang telah tersedia protokol kriopreservasi spermanya. Oleh karena itu, penelitian ini mencoba merangkum dan mengevaluasi protokol terbaik dalam proses kriopreservasi masing-masing spesies yang tersebut diatas. Aspek yang direview adalah jenis extender, krioprotektan, proses freezing (lama penyimpanan sperma dan suhu), thawing (lama thawing dan suhu) dan data hasil pengamatan (meliputi persentase motilitas, viabilitas, abnormalitas, fertilitas dan hatching rate.Kata kunci: Extender, Krioprotektan, Freezing, Thawing
