How can metabolic rate be measured in a goldfish?

Without sophisticated devices, this is tough to measure.\n\nUsing a metabolic calculator you can quantify input and output over time for the fish. If you have the devices to measure output from the water and monitor to to collect it all.\n\nYou can also do blood draws to meature serum levels of metabollic indicators.\n\nFor a more simple 'rule of thumb' approach, you could make a graph of food consumption per gram of fish at certain calculated temperatures. You would find that at the low and higher ends they consume more. At the lowest and highest ends trhey consume less and in the middle they consume the average of them all. It would be a bumpy bell curve. But that is not directly measuring metabollic rate.

Your Basal Metabolic Rate (BMR) is a measure of physiological and biochemical activity keeping you alive. It is usually measured in terms of oxygen consumption since the oxygen you take in is used to respire glucose to provide energy to drive the metabolic processes. The BMR is sometimes called Resting Metabolic Rate because the measurement is made when you are not doing anything other than keeping alive.\nDietary influences upon metabolic rate are unimportant, but exercise dramatically increases the rate. You can't eat or not eat anything that has any significant effect upon metabolic rate (unless you starve - a bad idea).\nYour metabolic rate is adjusted automatically in response to energy demand usually because of exercise/physical activity.\nThe only safe way to reduce body weight is to reduce the amount of energy-food (fat, starch & sugar) in a healthy, balanced diet. Exercise will contribute to weight loss (& have many other significant benefits) but it is eating less energy-food that is the most important.

I would like to bring to your attention a new concept in ADD testing. An objective physiological measure of ADHD has been elusive. However, research has shown that when an ADD person tries to sit still, do a boring task, or concentrate- they actually enter stress as measured by electro dermal activity. Measuring electron flow in a circuit the body operates largely by a series of electrical impulses which have been shown to follow certain pathways and measure changes in the electrical resistance or the ability of the tissue to conduct electricity. This marker is positive in the majority of ADD clients tested. Then GSR biofeedback may be used to improve the stress result. A protocol using this valid objective physiological marker has just been published in a video- "Guide for GSR Biofeedback Techniques for the Natural ADHD Practitioner".\n\n\n\nhttp://www.opednews.com/articles/life_a_jasonmar_060608_new_concept_in_testi.htm\n\nPod-cast interviews \nhttp://www.theadhdspecialist.com/gsraudio.html\n\nhttp://www.theadhdspecialist.com/gsraudio2.html\n\nResources/ books videos- published on helping ADHD naturally\n\n Screening test concept for ADHD with GSR biofeedback techniques \nhttp://www.amazon.com/gp/product/9659025149/

THere are a lot of ways. Entire textbooks are dedicated to this. Almost any way you can think of. IN terms of energy, bloodflow, chemical composition, excretion body composistion hormones....

I couldn't possibly tell you about your fish.  However, I CAN tell you that your question is in the wrong section.  Try posting it in PETS>Fish...you might get a better response.  This section is for HUMAN illnesses and conditions!

I used to keep fish. Goldfish to start with, along with Black Mollys, then got into tropical fish and then a salt water tank. It's a lot of work though, and can take up a lot of space, especially with a bigger tank and the equipment needed for a bigger tank. You want them to have enough space so they're not overcrowded.\n\nGoldfish are pretty easy and there are many ready-to-feed foods (flakes for example) for goldfish in pet stores. Get a book about goldfish (or other fish) or do research on line. Online might be best as the information would likely be more current.\n\nOther examples of "easier" fish and what they eat are:\n\n"GUPPY (Poecillia reticula):\nMiddle America: Prolific breeders. Males are very colorful. Active and peaceful. Livebearer.\nFoods: Flake Food. \n\nBLACK MOLLY (Poecillia sphenops):\nMexico to Venezuela: Suitable for beginners. Active, peaceful, eat algae. Prefers hard water. For propagation, breeding traps are recommended. Livebearer.\nFoods: Flake Food. \n\nSWORDTAIL (Xiphophorus helleri):\nMexico, Guatemala: Easy to maintain, but prospers only with varied diet. Livebearer.\nFoods: Flake Food, Color Food, BloodWorms. \n\nPLATY (Xiphophorus macalatus):\nMexico, Guatemala: Essential for beginners. Brings life and color to the aquarium. Livebearer.\nFoods: Flake Food, Color Food, BloodWorms. \n\nPEPPERED CATFISH (Corydoras paleatus):\nMiddle Amazon: Peaceful, charming bottom dweller. Feels more comfortable in an aquarium with small gravel or fine sand. Will clean up leftover food from the bottom. Scavenger.\nFoods: Tablets, Granules. \n\nSUCKERMOUTH (Plecostomus punctatus):\nAmazon: Peaceful bottom dweller. Prefers to eat at night, therefore, add one Tablet per large fish before turning off the lights. Scavenger.\nFoods: Tablets, Granules."\n\n-- http://home.ivillage.com/pets/birdssmallpets/0,,30n7,00.html

the rate of photosynthesis can be determined by measuring the rate of either O2 production or CO2 uptake. For right method to determine the rate of O2 produced during photosysnthesis refer the link.\nhttp://web.grinnell.edu/courses/bio/qubitmanual/Labs/PHS/pho.html.

By measuring the Biological Oxygen demand (BOD) or the Chemical oxygen demand (COD) \n\nhttp://en.wikipedia.org/wiki/Chemical_oxygen_demand\n\nhttp://en.wikipedia.org/wiki/BOD\n\nhope these are helpful :)

i believe the thing they used is called a calorometer. it involves burning the food and measuring the amount of energy that is released during combustion.

See if there's a difference in their rate of movement in cold, normal and hot conditions.

*Total Energy Requirements (kcal/day)= Basal Energy Expenditure + Activity Energy Expenditure + Specific Dynamic Activity\n\n\nWhere:\n***Basal Energy Expenditure in males: 66+ (13.7 x weight in kg)+(5 x height in cm) – (6.8 x age in years)\n***Basal Energy Expenditure in females: 655+ (9.6 x weight in kg)+(1.8 x height in cm) – (4.7 x age in years)\n***Activity Energy Expenditure:\n(Sedentary= 400 to 800 kcal/day)\n(Light work= 800 to 1200 kcal/day)\n(Moderate work= 1200 to 1800 kcal/day)\n(Hard work= 1800 to 4500 kcal/day)\n***Specific Dynamic Activity= Basal Energy Expenditure x 0.10\n\nIf you prefer avoiding calculation just use a Total Energy Requirements calculator on-line:\nhttp://www-users.med.cornell.edu/~spon/picu/calc/beecalc.htm

Don't worry. you can buy a physiology book. then buy a dead animal,  then anatomise it. just do it ,  success belong to you.  good luck!

You could try to provide environmental conditions similar to the ones in their natural habitat. Some fish are nocturnal and will be sleep-like in the presence of daylight, or viceversa. \nThere are also anaesthetics for fish, such as clover oil or MS-222. You should consult an animal physiologist before administering them, though.

Whichever you can do for the longest at the highest heart-rate.  Thats the best way to determine how many calories you are burning.  But you can't beat swimming.
