Squid Ink

If you prepare squids for your food, do not squeeze out and wash away their ink because it contains an anti-cancer substance.

This is the conclusion drawn by a group of Japanese scientists on the medicinal value of squid ink.

They discovered that squid ink contains mucopolysaccharide which is "involved in the healing of scars and formation of cartilage."

For more information, please read the excerpt below.

"A research group led by Hajime Matsue at the Aomori Prefecture Industrial Technology Center first announced in 1990 that squid ink contains substances with tumour inhibiting activity. The group has continued to pursue influential research since then. According to report by Matsue et al., while they were initially researching a mucopolysaccharide known as chondroitin sulphate (contained abundanly in cartilage and elsewhere), they noticed that mucopolysaccharides are also present in squid ink. Moreover, they showed that these were previously undiscovered types of mucopolysaccharide. Mucopolysaccharides, major components of cartilage, skin, and others, normally bond with protein to created a complex called proteoglycan, and are involved in the healing of scars and formation of cartilage.

"On measuring the tumour inhibition activity of this newly discovered mucopolysaccharide-peptide complex in squid ink, it was clearly found to have the effect of curing cancer. The experiment... was conducted as follows. One million cancer cells were injected into the abdominal cavity of a number of mice. Then the mucopolysaccharide-peptide complex from squid ink was injected tinto the abdominal cavity at the rate of 0.2mg per mouse two days later, four days later, and six days later. The progress of recovery from the cancer was then observed. zmice that had received no treatment at all died 2-3 weeks. But those treated with the mucopolysaccharide-peptide complex showed a 65% rate of recovery. Moreover, it was also proved that this mucopolysaccharide-peptide complex had hardly any direct toxicity towards the tunour cells, but that it activated the macrophage of the mice. Although it would be too hasty to draw the conclusion that eating squid ink cures cancer, it is beyond doubt that squid ink contains substances with outstanding bioactivity. Further research is therefore expected to develop in future."

Here is another study on squid ink that confirms this early study of Hajime Matsue.

"The anti-tumor activity of a new type of peptidoglycan isolated from squid ink was shown to have a cure rate of 64% for Meth A tumor from BALB/c mice. The ink delipidated in acetone, which contained the peptidoglycan at 0.1% (w/w), was administered to tumor-transplanted mice so as to examine the anti-tumor activity. One-fifth of the tumor-bearing mise was cured with 3 injections (1 mg/head) of the acetone delipidated squid ink or a prolongation of survival was observed in the treated animals, Heat treatment at 100 degrees C for 10 min did not affect the anti-tumor activity of the delipidated ink, its potentiality being preserved. The acetone-extractable fraction of the ink also brought about a similar cure rate for Meth A tumor. The delipidated ink enhanced the phagocytic activity of macrophages but no direct cytotoxicity was observed for the Meth A tumor cells. Hence it may be said that the anti-tumor activity of the delipidated ink was mainly due to the augmented cellular immunity in vivo." (Sasaki J. et al.)

If this is true, then many Filipinos would benefit from this discovery since the Philippines is producing a lot of squid. And squid is one commodity that has been a favorite among Filipinos.

Below is the Philippine squid production through the years, both from commercial and marine municipal waters.

The productions of squids from the municipal fishing areas from 1950 to 1976 are not available.

This writer failed to get the production of squid from 2002 and above.

Guimaras Strait: Focusing on Fish Production

By Melchor F. Cichon
September 13, 2006

The oil spill in Guimaras Province has been the talk of the town since the oil spill tragedy on August 11, 2006.

And people all over the world have been following this.

So what is the big deal about this incidence particularly to Filipinos?

As of September 9, 2006, according to the Ligtas Guimaras group, of the four municipalities of Guimaras, only the municipality of Buenavista has not been affected by the oil spill. Of the 40 barangays of Guimaras, 26 have been affected that also include 4,533 families and 22,665 persons.

Let us also focus on the fish production of Guimaras Strait.

Guimaras Strait is located between the provinces of Guimaras and Negros Occidental, and one of the most productive fishing grounds in the Philippines.

How this oil spill will affect the fish production of this fishing ground, we cannot at the moment say anything, except to pray that the damage will not be tremendous. For sure, some of the foods of fishes found in this fishing grounds like planktons will be killed by the toxin found in oil slick. With less food would mean less fishes that will strive in the area.

If we look at the productions of Guimaras Strait since 1953 (that is the oldest record this writer could get) up to 2000, we can say that Guimaras strait has been producing tons of fishes. The online news report in the BAR Chronicle vol. 5, no. 4, April 1-30, 2004) states that the average total annual fish production of Guimaras is 50, 000 metric tons.

Here is the part of that news item:

"The study (three-year project entitled, Ocean Color for Sustainable Fisheries (OCSF) funded by the Bureau of Agricultural Research of the Department of Agriculture (DA-BAR ) ) also identified the most productive fishing grounds that have an average of annual fisheries production of 50,000 metric tons and above. These are the: Moro Gulf, East Sulu Sea, Visayan Sea, South Sulu Sea, Visayan Sea, Bohol Sea, and Guimaras Strait. These areas contribute to one-half of the total annual fish production in the country. " (The title of the study supplied)
For a clearer view of the annual fish production of Guimaras Strait from 1953 to 2000, I patiently copied the commercial annual fish production of Guimaras Strait from the Philippine Fisheries Statistics and the Philippine Fisheries Profile since 1953 to 2000. This is what I got:

What are the fishes found in Guimaras Strait?

Based on the Fisheries Statistics issued by the Bureau of Fisheries and Aquatic Resources, these are some of the commercial fishes and other aquatic resources in this fishing ground:

Barracuda,Cavalla,Clams,Cockles,Crevalle,Dolphin fish,Flounders, Flying fish,Fusilies,Glassfish, Goatfish,Goby,
Grouper,Jacks,Jelly fish, Lizard fish, Marine turtle,Milkffish,Mojarra, Moonfish, Moray, Mullets, Mussels, Scallops, Oysters, Perchlet, Scads, Sea bass, Sea catfish, Sea cucumber, Sea perches, Sea urchins, Seaweeds, Shads,Sickle fish, Siganids, Sillago, Slipmouth, Snappers, Spade fish, Sponges, Surgeon fish, Threadfin, Wrasses, and other aquatic plants.
