Night Time Pond Viewing




ALOHA: Our Luau was a tremendous success. members and guests began arriving about 4:00pm. They were greeted with a lei and signed in. most dressed in Hawaiian shirts and blouses and were ready to party ! !. Pam Spindola`s backyard was the perfect setting for this event.Tiki torches, Island music and the food ? to die for.! ! Pupus started the evening with spring rolls, beef skewers teriyaki and shrimp won tons that was just for starters. Our meal was Kalua pork, and boneless breast of chicken teriaki style plus all the goodies that make a great meal.


It was a warm evening but not that bad to spoil a good time. I have to give special thanks to the folks that made this happen, Carol Simoes our vice- president, Pam Spindola, Bob Stumpf and Connie Freihoff. I know these folks worked as a team and spent hours in the planning. I have found that when its done and over a feeling of satisfaction for a job well done takes over. I think these folks got the same vibes.

And now the dancers , 4 girls to guys and a drummer. I looked at the members and guests and saw smiling faces. The dance review had very color full costumes and the girls were lovely. They entertained us for about an hour with different costumes and Island visits. All I can say it was money well spent and i hope you all enjoyed yourselves.


Your president,
Louie Hernandez, Mahalo

About Koi

These are answers to commonly asked questions on Koi:


1. Maximum life span is over 200 years in exceptional cases; average life span is usually 25-35 years.

2. Maximum length is about three feet. Koi will reach 18 inches in three to four years, depending on the pond size, food and water conditions.

3. We feed our fish once or twice per day depending on the season. Koi can go ten or more days without food without harm. They will eat almost anything, but we feed them pellets that are specially formulated for Koi. These pellets come in different sizes and varieties. Koi can also be fed dried or fresh shrimp, lettuce, cooked rice or cooked oats.

4. Some of our fish are imported from Japan by air freight. The rest of our stock are the results of our own breeding operations here in California. Koi are transported in plastic bags with water and oxygen and packed in cardboard boxes.

5. Our ponds are not heated, but the water is constantly aerated and filtered. Our filters are cleaned regularly even though the pond water appears to be clear.

6. The selling price of Koi is determined by size, body shape, color, pattern, and availability.

7. Koi can withstand a wide range of temperature, but sudden changes in temperature are not good for them. They can survive under the ice in extreme cold as long as the water does not freeze solid. Koi are less active and eat less in cold water.

8. Some individual fish just inexplicably die, but overall, Koi are remarkably hardy and healthy fish, much more so than goldfish or tropicals. Chlorine or chloramines in the city water and windblown insecticides are very dangerous to Koi. Smaller Koi have a much higher mortality rate than larger Koi and are more susceptible to diseases and changes in environment.

9. Koi get along well with goldfish and other tropical fish, as long as the other fish are not aggressive or small enough to eat.

10. Koi can be kept in aquariums as well as ponds. Aquariums need good filtration and aeration systems. A filter utilizing carbon is recommended for aquariums.

11. Koi are not live bearers but lay thousands of eggs in a single breeding. Koi must be at least three to four years old and of sufficient size before they breed. Koi require special water conditions and environment before breeding. The eggs and baby Koi must be separated from the adult Koi or they will more than likely be eaten. The baby Koi hatch in about 3 to 7 days depending on the weather. The survival rate for baby Koi is less than 50%.

12. There are several color varieties of Koi, each with a different name. Koi with more than one color are unique in that there are no two that look exactly alike.

13. Raising Koi can be a fascinating and relaxing hobby. For the avid Koi enthusiant, there are Koi shows in which Koi compete according to their size and class.

14. For more information on Koi, ponds, and water gardens the following books are recommended. AKCA books can be order by phone from the AKCA Book Store at 800.646.1685.
