Pertumbuhan merupakan pertambahan ukuran sel atau organisme yang berlangsung secara kuantitatif atau terukur. Sementara perkembangan (diferensiasi) adalah proses menuju kedewasaan pada organisme, merupakan perubahan dari keadaan sejumlah sel membentuk organ-organ yang mempunyai struktur dan fungsi yang berbeda. Pertumbuhan juga dapat diartikan sebagai perubahan ukuran suatu organisme yang dapat berupa berat atau panjang dalam waktu tertentu. Terdapat dua macam pertumbuhan yaitu ...

Age seaweed seedlings reflects the level of productivity of seaweed to grow and evolve, including the ability to optimize the process of photosynthesis. Seaweed seedlings obtained from breeding centers should aged 20-25 days to provide maximum growth. Seaweed seedlings were too young to need a period of adaptation in advance and still relatively vulnerable to changes in water quality. Whereas ...

The movement of water is the main ecological factors that control the conditions of sea grass communities. Currents and waves have a considerable influence on the aeration, nutrient transport and stirring the water. Stirring the water acts to avoid large temperature fluctuations (Trono and Fortes, 1988). Another role of the currents is to avoid the accumulation of silt and epiphytes ...

Salah satu cara untuk mengukur kecerahan air dilakukan dengan menggunakan keping Secchi (Secchi-disk), yaitu sebuah keping bulat dengan garis tengah 20 cm yang terbuat dari seng dan dicat putih atau hitam-putih yang diberi pemberat. Alat tersebut diturunkan ke dalam air sampai tidak tampak, kedalamannya diukur, kemudian diturunkan lebih dalam lagi. Selanjutnya keping tersebut diangkat kembali dan apabila keping hampir tampak ...

Strain is a group of organisms that are members of a species that has special characteristics but do not be a descendant or variation separately. One factor the emergence of diversity in a species is geographic isolation. Geographic isolation causes offspring have different characteristics from the parent due to the interaction between the genotype and the environment. Seaweed Kappahycus alvarezii ...
Read More »Seaweed Growth Rate Calculation
The growth of seaweed categorized in somatic growth and physiological growth. Somatic growth is growth as measured by weight gain, long thallus while the physiological growth seen by reproduction and koloidnya content. The growth rate is calculated according to the weight gain of the seeds planted and expressed as a percent per day. Growth rates necessary to forecast production at ...
