An investigation was carried out to study the effects of single and double injection of given dose of pituitary gland (PG) on the breeding performance viz., ovulation response, fertilization, and hatching of climbing perch, Anabas testudineus was tested. Pituitary gland dose of 1.2 mg/100g was used in this experiment. Twenty female fish was arranged into two treatments: T1 and T2, each with 10 replications. In T1, the entire dose was administered in a single injection and in T2 the same dose was given in two equal injections three hr apart. The experiment was laid in completely randomized design (CRD). It was found that administration of PG in split doses (double injection) had no additional advantages (ovulation 100%, fertilization 81.56% and hatching 72.68%) over the single injection (ovulation 100%, fertilization 83.03% and hatching 75.48%) treatment. Similarly, the ovulation time of the fish did not vary significantly in either single or double injection of PG (single injection 7.12 hr; double injection 7.20 hr). The results demonstrated that splitting of pituitary gland dose (double injection) has no additional advantages on breeding performance of A. testudineus. Therefore, single injection may be preferred over the second injection for breeding of this fish. Key words: Breeding, pituitary gland (PG), fertilization, hatching J. bio-sci. 14: 57-60, 2006

ABSTRACT Ivy gourd is an underutilized vegetables found in the North of Minas Gerais State-Brazil. It is mainly consumed raw as salad. Pickling fruits can enhance the commercial exploitation of this species. However, no information on the processing techniques of the ivy gourd fruits in Brazil is found in literature. The objective of this study was to evaluate the quality parameters in the production of pickled ivy gourd. The treatments consisted of three bleaching times (3, 6 and 9 minutes), using a completely randomized design, with seven replicates. We evaluated the traits: instrumental analyzes of pH, color, total titratable acidity, soluble solids, texture and sensorial affective tests. The pH is within the indicated range (below 4.5) and the bleaching time influenced the color and texture alteration since the sample under 3-minute bleaching presented a greater tendency for green and greater firmness. For the sensory analysis, no significant difference related to sensory scoring was noticed; in relation to mode value, we concluded that the 6-minute sample was more preferable, though. For titratable total acidity and soluble solids analyses, no significant differences between the samples was noticed, considering that both parameters were within the standard when compared to other literature. We concluded that heat treatment influenced only the texture and color intensity and the preserved product showed good acceptability.
