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.

beach is a local tourism site which is located in Tasikmalaya, West Java.
Marine debris is the problem for improving the tourism development in that
location. International Coastal Cleanup (ICC) concept had been introduced to
local people and local tourists. There was several important points obtained
from this introductory activity. First, the concept was able to improve people
and tourists understanding of coastal cleanness. Second, it has improved people
awareness of marine debris. Third, continuity of this program and extra cleanliness
tools are needed in order to develop this local tourism.

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.
