چکیده

Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian tepung bunga marigold pada pakan komersil terhadap kecerahan warna ikan guppy. Penelitian dilaksanakan selama 50 hari, dengan metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 kali ulangan, yaitu: P1 (kontrol), P2 (tepung 0,5%), P3 1%), P4 (Tepung 1,5%). diawali pembuatan marigold, dicampurkan pelet sesuai perlakuannya. Pakan selanjutnya diuji secara biologis guppy dibudidayakan. Parameter diukur berat mutlak, panjang laju pertumbuhan spesifik, rasio konversi pakan, kelangsungan hidup, kandungan karotenoid, warna. Data dianalisis ANOVA dilanjutkan uji Duncan. Hasil menunjukkan bahwa penambahan dapat meningkatkan mempengaruhi hidup (SR) (P<0,05), namun tidak berpengaruh (FCR) (P>0,05). Penambahan sebesar 1,5% (P4) karotenoid 13,80 µmol/g, didukung oleh nilai redness (a*) 31,37, yellowness (b*) 37,68, lighteness (L*) 28,25, hue 58,15, tingkat 93%±0,06.

Social networks in the guppy (Poecilia reticulata).

Social network theory is used to elicit details of the social structure of a population of free-ranging guppies, Poecilia reticulata. They were found to have a complex and highly structured social network, which exhibited characteristics consistent with the 'small world' phenomenon. Stable partner associations between individuals were observed, a finding that fulfils the basic prerequisite for ...

Aerial Jumping in the Trinidadian Guppy (Poecilia reticulata)

Many fishes are able to jump out of the water and launch themselves into the air. Such behavior has been connected with prey capture, migration and predator avoidance. We found that jumping behavior of the guppy Poecilia reticulata is not associated with any of the above. The fish jump spontaneously, without being triggered by overt sensory cues, is not migratory and does not attempt to capture...

Studies of In Vitro Embryo Culture of Guppy (Poecilia reticulata)

Different with other fishes, the guppies (Poecilia reticulata) is ovoviviparity, which retain their fertilized eggs within the follicle throughout gestation. The synchronously growing diplotene oocytes store nutrients in droplets and yolk, before their maturation and fertilization. The lecithotrophic strategy of development entails the provisioning of embryos with resources from the maternal yo...

Mechanisms underlying shoal composition in the Trinidadian guppy, Poecilia reticulata

Free-ranging groups are frequently assorted by phenotypic characters. However, very little is known about the underlying processes that determine this structuring. In this study, we investigate the mechanisms underlying the phenotypic composition of shoals of guppies (Poecilia reticulata) in a high-predation stream in Trinidad’s Northern Mountain Range. We collected 57 entire wild shoals, which...

Avoidance Learning and "Personality" in the Guppy (Poecilia reticulata)

The authors examined the relationships between 2 "personality" dimensions (Approach and Fear Avoidance) and 2-way active avoidance learning performance in the guppy (Poecilia reticulata). Contrary to expectations (based on prior rodent studies), higher fearfulness facilitated both earlier appearance and acquisition of the shuttlebox avoidance responses, especially in the less exploratory and ac...
