Trochus sp was gastropod which is a herbivore. Have a natural habitat in coral reefs of the Indo-Pacific waters. In addition to consumption, shell Trochus sp. has the highest economic value which caused the demand is high, and resulting the reduction in natural populations. Trochus sp including one of protected species in Vietnam. Basic information about the ecology and reproductive biology of Trochus sp can provide the knowledge to assure the survival and availability of these organisms in nature. Trochus sp plant-eating animals, and eat green plants and red algae (Cyanophycae and Phaeophycae). They also looking in benthic area for diatoms and benthic foraminifera (Asano 1944). The Natural habitat of Trochus sp in the coral reefs, usually found in the area of ​​reef flat. Maximum density found in reef areas are facing the wind but can also be found on the coral reefs that are at lower limit of the wind, in the intertidal zone and subtidal zone in shallow water (Kitutani and Yamakawa 1999). The maximum depth of Trochus sp to growing was to 10 m, although they can also be found at a depth of 25 m (Bertram 1998). Trochus have spawning at the high tide, with external fertilization and performed at night (nocturnal spawning). According to Sims (1988), Trochus spawn approximately three to five times a year. Small Trochus can growth faster than adults. The higher of Trochus growth rate is in the dry season (March to October) compared to the rainy season (November to March).

WorldView-2 sensor, which was launched in October 2009 represents a new achievement in geographic information systems, especially in the marine field. Differences WorldView-2 sensor with sensor-owned satellite that has gone before is located on four new band that has the coastal band, yellow band, red edge band, and near-IR 2 band. Coastal band sensors are specifically designed for applications in the littoral zone or shallow sea. This is very helpful in mapping the depth or bathymetry. This is not only important for navigational purposes but also in seeing the shipping processes of coastal disaster mitigation planning and even in coastal areas such as tsunami and storm surge. This paper gives an overview of how the application of WorldView-2 imagery for mapping shallow sea bathymetry can be done based on methods and approaches that has been already available for the other sensor.

Fish and invertebrate aquatic animals are very sensitive to cyanide exposure. Free concentration in the environment can reduce the ability to swim and inhibit reproduction of many species of fish. Another adverse effect is pathology, sensitivity the nature of predators, impaired respiratory system, disorders of osmoregulation and different growth patterns. The networks that depend anaerobic respiration, such as primary liver and nervous system was also affected. Fundamental changes where associated with toxin by hydrogen cyanide (HCN) is distinguished in three categories, the sensors, motor and interneuronal depends on how much damage is take. HCN may cause cell death or survival but there is damage in small sections of dendrites or axons, so that shrinkage or loss of entire functions. In fish it will lose swimming ability for a moment, and when in large doses cause of death.

The aim of this research was to determine the copepod daily feeding to Dunaliella salina and Chlorella sp because the research of copepod daily consumption to the phytoplankton in the sea was a part of discovering the water productivity. The determination was needed in the laboratory experimental method, in order to qualifying the biomass and energy transfer of sea food web / chain. The observation based on the laboratory experimental method and conducted in the Hatcehery and Laboratory of Alga, Marine Station, Teluk Awur Jepara. Four treatment were applied during the observation, i.e.: A. D.salina 20 litre; B. D.salina  2 litre; C. Chlorella sp 20 litre; D. Chlorella sp 2 liter. The copepod grazing rate was determined base on parameter of cell phytoplankton/ ml/ hour/ copepode. There were 4 series observation. The observations were done for 36 hours with 3 hours interval. The data collected was arranged as copepod daily consumption and analyzed using MAXIMS Analysis Models. The highest copepod daily grazing rate was 88.02 ± 44.18 cell phytoplankton/ ml/ hour/ copepod for D.salina on 20 liter volume of media. While the lowest one 50.16 ± 43.99 cell phytoplankton/ ml/ hour / copepod for Chlorella sp on 2 liters volume media. The Copepod daily grazing model tends to form a constant model for D.salina on 20 liters of media and proportional model for 2 liters volume of media. The Chlorella sp on 2 liters volume of media graze by the copepod showed the same model for constant and proportional model. The water quality of the media remained in tolerance range to support the grazing rate of copepod to the phytoplankton during the research.
