Cage Culture of Grouper (Lapu-lapu) Part 2
Summary
TLDRThe video discusses the feeding and growth cycle of grouper fish in aquaculture. It explains how smaller fingerlings are fed more frequently to reduce cannibalism, while larger fish, once they reach 150g, are fed only once a day to prevent waste and environmental pollution. The cycle for growing grouper to market size takes about 16 months, with the first harvest occurring at 12 months. Grouper is highly valued in Asia, providing a high return on investment despite the long cycle, making it a profitable choice for fish farming.
Takeaways
- 🐟 Feeding small fingerlings multiple times daily reduces cannibalism and supports growth.
- 🍽️ Once the fish reach 150g, they only need to be fed once daily to prevent waste and pollution.
- 📏 Feed amount should be 3-5% of the fish’s body mass, exceeding this leads to waste.
- 📦 TTI feed is preferred for its availability, quality, and timely weekly deliveries.
- 📅 The typical growth cycle for grouper to reach market size is around 12 months, but full cage harvest takes up to 16 months.
- 💰 Grouper farming is chosen for its high market price, especially in Asia, despite the long growth cycle.
- 🔁 Only 20% of the fish reach market size in 12 months, with the remainder taking 14-16 months.
- 📉 Feeding frequency and pellet size decrease as the fish grow, reducing operational costs.
- 💼 Grouper farming is highly profitable due to the high market price and lower feeding costs after reaching 150g.
- 🌍 Aquaculture parks are suitable for foreign investors, offering job opportunities and economic benefits to local communities.
Q & A
What is the recommended feeding schedule for 1-inch fingerlings?
-For 1-inch fingerlings, they should be fed as often as they are willing to eat to prevent cannibalism. Typically, they are fed fry mash since their mouths are not large enough for bigger pellets.
How should feeding be adjusted as the fish grow larger, particularly after they reach 150 grams?
-Once the fish reach 150 grams, they should be fed only once a day, usually at dusk, as they tend to purge any excess food and waste it. Feeding more frequently can lead to environmental pollution and financial waste.
What percentage of body weight should be fed to the fish?
-The fish should be fed 3% to 5% of their total biomass. More than 5% results in wasted food, which affects both the cost and the environment.
What are the advantages of using TTI feed for grouper farming?
-TTI feed is valued for its availability, good formulation, and technical support. It is distributed in the area, delivered weekly, and the company ensures timely deliveries, which prevents the need for excessive storage and reduces the risk of disease.
How long is the full growth cycle for grouper fish until harvest?
-The full growth cycle for grouper is about 16 months, with the first group of faster-growing fish ready for harvest in 12 months. Slower-growing fish take around 14 to 16 months to reach market size.
Why is grouper chosen for aquaculture despite the long growth cycle?
-Grouper is chosen for aquaculture because of its high market price, especially in Asia. While the cycle is longer than other species, the return on investment is much higher due to the higher price per kilogram.
What market price does grouper fish currently fetch in Cebu?
-In Cebu, grouper currently fetches about 485 pesos per kilogram, making it a highly profitable species for aquaculture.
How does the feeding strategy for grouper differ from other fish species?
-Unlike other species that need to be fed three times a day, grouper only needs to be fed once a day after reaching 150 grams. This reduces feed costs and increases the profit margin.
What are the benefits of setting up fish farming operations in special zones for foreign investors?
-Special zones for foreign investors are pre-selected for their suitability for fish farming, ensuring optimal growing conditions. These zones help create jobs for the local community, from cage work to potential processing plant operations, transportation, and more.
What is the broader economic impact of fish farming in the community?
-Fish farming stimulates economic activity by creating jobs not only in fish farming but also in processing, transportation, and other related industries. This economic activity benefits entire communities and helps meet global food demand.
Outlines
🐟 Feeding Techniques for Young Fingerlings and Growing Groupers
The first paragraph discusses the feeding habits and requirements for young groupers, particularly fingerlings, which are fed fry mash due to their small mouth size. The importance of frequent feeding is emphasized to prevent cannibalism. As the fish grow, the feeding frequency decreases, and groupers weighing around 150g only require one feeding per day at dusk. Overfeeding leads to waste and environmental pollution, so it's recommended to feed the fish 3-5% of their body mass. The speaker also highlights the benefits of using TTI feed, a reliable supplier in their region, which helps maintain fish health and avoid stockpiling issues.
⏳ Growth Cycle and Market Value of Groupers
This paragraph delves into the growth cycle of groupers, explaining that while about 20% of the stock reaches market size (500g) within 12 months, the full cycle for all fish to mature and be harvested can take up to 16 months. The text emphasizes that groupers are a valuable species in the market, particularly in Asia, with high returns on investment due to their premium price, despite the longer culture cycle compared to other species. The speaker also highlights that while grouper feeding takes less effort compared to other fish, the longer cycle still results in a favorable profit margin.
🌱 Economic and Social Impact of Grouper Farming
The final paragraph covers the broader economic and social benefits of grouper farming, particularly in specialized zones for foreign investors. The speaker encourages investment in this business, citing the high demand for fish and the economic activities that surround fish farming, such as processing plants and transportation. Additionally, they highlight how teaching proper fish culturing techniques can benefit local communities by creating jobs and promoting sustainable practices. The speaker emphasizes the importance of maintaining environmental standards to ensure the long-term viability of marine species production.

Highlights
Fingerlings are initially fed fry mash as their mouths are too small for larger pellets.
Feeding the fish as often as they want helps reduce cannibalism among groupers.
Once groupers reach 150 grams, they only need to be fed once a day, typically at dusk.
Overfeeding groupers leads to waste and environmental pollution, so feeding should be limited to 5% of their body weight.
Tati feed is the preferred choice due to its availability and the regular weekly deliveries.
Storing too much feed can lead to disease, so maintaining a steady supply with regular delivery is crucial.
The grouper farming cycle can take up to 16 months, with some fish growing faster and reaching market size in 12 months.
Grouper is highly prized in the Asian market, making it a valuable species for aquaculture despite the long farming cycle.
The cost of inputs like labor and cage building is similar across species, but grouper yields a much higher return due to its market price.
Feeding grouper only once per day after they reach 150 grams significantly reduces feed costs compared to other species.
Even though the farming cycle is longer, grouper farming offers a high return on investment due to lower feed costs and high market value.
Aquaculture in special zones for foreign investors ensures suitability for fish growth while providing economic opportunities.
Developing grouper farms creates jobs in both cage maintenance and other areas like processing, transportation, and feed mills.
The potential for economic growth through grouper aquaculture is significant, benefiting communities and creating sustainable jobs.
Sustainability and environmental preservation are key to maintaining successful grouper aquaculture operations.

well with with with a 1 in traditionally
you know the the 1 in or the 2in uh
fingerling is going to be handled about
the same way um with the 1-in fingerling
uh they're going to eat the the fry Mash
right in the beginning uh their mouths
are not big enough to take the the the
larger pellet so we have to give them
the size of feed that they're able to to
actually fit inside their mouth um what
what we what we like to do is feed them
as often as they want to eat uh that's
going to help with the the cannibalism
that occurs with this species if your
grouper well fed they're not going to
feed on you know the your stock Inside
the Cage so you know we like to keep
them fed you know maybe six or seven
times as many times as they will eat uh
that's what what I recommend for the
small ones um once they grow a little
bit more then you can adjust the the
feeding um probably when they're about 2
or 3 in you probably can feed them three
times in a day in the morning maybe in
the afternoon and in the evening uh what
we find is that once they reach 150 g
the they really only want to eat one
time in a day and we feed them at dawn
so uh excuse me at dusk right it's dusk
uh we feed them at about 5 PM PM once
once they're 150 g uh they really only
will eat one time in a day if you feed
them more they'll just really Purge the
food out and and and it will be waste
it's waste out of your out of your cost
and it's waste for the animal and it it
pollutes the environment so we only
really recommend one feeding a day after
they're 150 g um as far as the the
amount of food that we feed them it's a
percentage of the actual biomass and uh
we're feeding them between three and 5%
of their entire body mass so uh the way
you would calculate that is you take a a
sampling of the fish you estimate the
size and then you calculate the amount
in kilos that is inside by how many
pieces you have so you know it's it's a
ratio for sure but you know more than 5%
we're finding that it's waste you know
so the the really the recommendation for
that animal is 5% of their body weight
we we we we are using tati feed and
we're we're happy that tati feed is is
actually Distributing here in BHO nobody
else I think uh distributes high value
uh feed for for our group or um they're
the only ones in the area in bhul that
are Distributing the feed so so we're
happy to use TTI feed cuz it's available
uh we like the formulation our fish are
healthy and uh you know we we we have uh
our representative come here once a week
and he checks up on us if we need if we
need him to he always has the feet here
on time so you know they they deliver
every Tuesday to us in our area and you
know so it helps us that we don't have
to keep too much stock on hand you know
to have a regular delivery that way we
don't you know we don't incur any of the
the diseases or the problems that that
happen when you store too much food and
you're not disposing of it uh quickly
enough so you know yeah has really
helped

environmental already avail
techical support through feeding
management cage management at
management well you know the the the the
all the literature that I had read when
I originally started culturing this was
was giving a 12-month cycle um what
we've actually learned learned is that
the cycle is a little bit longer than
that uh the shooters will grow to Market
size which is 500 G in 12 months uh but
you're only seeing about 20% of your
stock of Any Given stock being being
fast Growers about 60% will grow let's
just say at a standard rate and then the
the the rest of the 20% will grow
relatively slowly
so if if you're going to talk about the
entire Cage being liquidated uh you may
see 16 months between you know when you
first stock and then when you harvest
your last one uh of course the shooters
will be first uh they'll grow relatively
quickly in 12 months uh then you'll see
somewhere 14 months and then finally the
the slowest growing ones in 16 months so
we're we're we're seeing an
actual uh cycle of about 16 months to to
empty the entire
stock uh the reason we chose grouper to
culture grouper um is because the
difference in the market price from
other fish that we have available to us
uh grouper is actually um very highly
prized not only in the Philippines but
in all of Asia um it's one of the
highest uh priced fish of of really
anything that they're pulling out or
culturing um so what what we're seeing
is that all the capital inputs are
relatively the same the labor costs are
the same you know the cost to build the
cages are the same the Nets are the same
the only difference is the the market
price of the fish at the end of the
cycle um the really the only hindrance
to to culturing grouper is the long
cycle uh you must be willing to to wait
the one year the 14 months uh before you
return but if you're thinking about a
12- month cycle you're you're going to
return higher than you would culturing
bangus or milk or excuse me of rabbit
fish or any other species it it's it's
actually we're we're seeing a pretty
high return on it uh right now the the
market price for grouper in subu
it's probably about 485 pesos a kilo um
so you know we definitely like that
market price uh we're we're seeing a
very high return on our investment here
it's just the cycle is a little bit long
you know the the the other aspect is is
the feeding the the amount of kilos that
imp pelletized feed that it takes you
know with with uh a lot of the other
species you're you're you're feeding
them three times in a day and with
grouper you know you're really only
feeding them one time in a day after
they get to 150 g so you know even
though the cycle is is longer uh the
actual return on investment is much
higher uh the profit margin is is very
nice when when you actually come to
Market with your fish so you know we for
that reason we we we like grouper for
sure
partner well you know I'd like to
encourage anybody to to to to to do this
kind of business but you know here you
know in this park it's it's suited for
foreign investors um generally uh
Filipino national can culture fish
anywhere they would choose to any
suitable place um for for a foreign
foreign National you know we're pretty
much restricted to these special zones
which is you know it's fine these areas
are pre-selected for their suitability
for growing fish
um if you have the time and also some
free Capital you know I I I think you
can multiply your Capital by doing this
business fish is fish is in demand here
I mean just like anywhere else um the
high valued species of course are are
commanding a higher price but as far as
uh you know the technical
knowledge it's easy to learn you know
it's it's nothing that you know is
beyond anyone's capacity you know for
for most of the the the people here
they're already they're already engaged
in some sort of fishing activity and
just to teach them the proper techniques
to culture the fish you know it will I
think you know will benefit not only
them but their families and their whole
communities what what we like about this
park is that once we develop it you know
there's going to be a lot of jobs here
you know for not only the people that
are actually working on the cages but if
we set up processing here there'll be
people uh working in the processing
plants uh if there's a food mill or any
other any other thing you know
Transportation um there's just lots of
economic activity that happens and
surrounds this this business so you know
the more economic activity we have the
more jobs we can create for our own
individual communities so you know I
think it's more profitable than lots of
other businesses that are that are
really being engaged in right now and
you know it's it's we're doing a good
thing we're we're growing food for the
world you know so you know you can feel
good about what you're doing you can
feel good about what what where your
money is multiplying from you can you
can there's lots of things to feel good
about you know as long as we're taking
care of our environment and making sure
that the area that we grow in stays
pristine and suitable for for production
of marine species you know the the
potential for these sites is is
incredible
